Semejanzas y diferencias de los tipos de cuenta
Para implementar la monitorización de los eventos sucedidos en una cuenta de tipo compensación, debemos entender la diferencia entre las
cuentas de cobertura y compensación.
Las diferencias se relacionan con la representaciónde las posiciones. En una cuenta de cobertura, podemos abrir el número que deseemos de
posiciones de un mismo símbolo, mientras que en una cuenta de compensación, solo podremos abrir una. Las cuentas de cobertura permiten
cerrar una posición con el volumen de otra que tenga dirección contraria: es el llamado cierre de posición por otra opuesta.
En este caso:
- Si el volumen de la posición opuesta es inferior al volumen de la posición a cerrar, la posición opuesta se cerrará por completo, mientras que la posición a cerrar lo hará parcialmente,
- si el volumen de la posición opuesta es superior al volumen de la posición a cerrar, la posición opuesta se cerrará parcialemente, mientras que la posición a cerrar lo hará por completo,
- si el volumen de la posición opuesta y la posición a cerrar es igual, se cerrarán ambas posiciones;
- Cada posición tiene su propio identificador de posición, que es igual al ticket de la orden abierta. Este identificador no cambia durante toda la existencia de la posición;
- Cada posición tiene su propio ticket, que es igual al ticket de la orden cuya activación ha provocado la apertura de la posición;
- si enviamos una solicitud de apertura de una nueva posición en la dirección de la posición actual, se abrirá una posición con un nuevo identificador y ticket.
En una cuenta de compensación, el trabajo con una posición en un símbolo no permite cerrar una posición con otra opuesta, pero, en una situación lejanamente parecida (al activarse una orden que tenga la dirección opuesta a la de la posición actual), esta posición puede ser parcialmente cerrada, o cerrada por completo, o cambiar su dirección:
- Si el volumen de la orden opuesta activada es inferior al volumen de la posición actual, la posición se cerrará parcialmente,
- si el volumen de la orden opuesta activada es igual al volumen de la posición actual, la posición se cerrará por completo,
- Si el volumen de la orden opuesta activada es superior al volumen de la posición actual, la posición cambiará de dirección, es decir, se dará un viraje;
- Cada posición tiene su propio identificador de posición, que es igual al ticket de la orden abierta. Este identificador no cambia durante toda la existencia de la posición;
- Cada posición tiene su ticket, que es igual al ticket de la orden cuya activación ha provocado el viraje de posición; El ticket puede diferenciarse del identificador, y en cierta medida repite los tickets de multitud de posiciones en la cuenta de cobertura;
- Si enviamos una solicitud de apertura de una nueva posición en la dirección de la posición actual, al volumen de esta se le añadirá el
volumen de la orden activada, mientras que el ticket de la posición no cambiará.
Implementando el procesamiento de eventos en una cuenta de compensación
Para implementar la monitorización de los eventos sucedidos en una cuenta de tipo compensación, seguiremos el camino sencillo: dividiremos el procesamiento de los eventos que suceden con las posiciones según el tipo de cuenta. El código resultante será mayor, pero la lógica será más comprensible, gracias a la división de la funcionalidad. Más tarde, después de la depuración y la confirmación de la estabilidad del funcionamiento, optimizaremos el código y eliminaremos todo lo sobrante.
Al añadir una nueva constante a las enumeraciones de los tipos de evento, hemos notado que la clasificación no funciona bien en algunos casos. Al aclarar los motivos de ese comportamiento, se ha esclarecido que no solo tiene valor la correspondencia de las propiedades u órdenes con la clasificación de dicho tipo, sino también su ubicación en la enumeración, independientemente de que cada constante esté enumerada. Así, si para la búsqueda no se usa alguna propiedad, no basta con omitirla y asignar los números correctos a las constantes de enumeración de los métodos de búsqueda que se correspondan con las constantes de enumeración de los tipos de propiedades: también es importante colocar las propiedades u órdenes no utilizadas en la clasificación al final de la lista de este tipo de propiedades. Para calcular el número inicial de los siguientes tipos de propiedades, el número de propiedades no usadas dentro de la cantidad de propiedades de tipo anterior debe ser restado del índice de tipos de propiedad inicial.
Para comprobar que hemos creado correctamente las enumeraciones de los métodos de clasificación, se ha añadido una pequeña función al archivo de funciones de servicio DELib.mqh:
//+------------------------------------------------------------------+ //| Display all sorting enumeration constants in the journal | //+------------------------------------------------------------------+ void EnumNumbersTest() { string enm="ENUM_SORT_ORDERS_MODE"; string t=StringSubstr(enm,5,5)+"BY"; Print("Search of the values of the enumaration ",enm,":"); ENUM_SORT_ORDERS_MODE type=0; while(StringFind(EnumToString(type),t)==0) { Print(enm,"[",type,"]=",EnumToString(type)); if(type>500) break; type++; } Print("\nNumber of members of the ",enm,"=",type); } //+------------------------------------------------------------------+
Para comprobar los componentes de la enumeración de los tipos de clasificación, deberemos introdicirlo manualmente en dos líneas de la función (no hemos encontrado un método para hacer automática la indicación de una enumeración concreta en la línea ENUM_SORT_ORDERS_MODE type=;).
Ahora, si en el manejador OnInit() del asesor de prueba llamamos esta función, se mostrarán en el diario de registro todas las denominaciones de
las constantes de la enumeración establecida y sus índices correspondientes.
Precisamente al comprobar los componentes de las enumeraciones, detectamos que se habían creado de forma incorrecta. Para corregir
este error, hemos tenido que mejorar un poco las enumeraciones en el archivo
Defines.mqh.
Solo tenemos que indicar otro orden se secuencia de las constantes en las enumeraciones: ubicamos
las propiedades no usadas en la clasificación al final de la lista de constantes de la enumeración de propiedades del objeto, y
añadimos
macrosustituciones para indicar el número de propiedades utilizadas
para la búsqueda y clasificación. Usaremos estas macrosustituciones al
calcular los índices iniciales de las propiedades en las enumeraciones de la clasificación, lo cual redundará en el cálculo de los
índices correctos de las constantes iniciales en las enumeraciones.
Asimismo, añadiremos nuevos tipos de constantes para los eventos en las
cuentas de compensación y constantes para guardar el número mágico y el símbolo
de la posición opuesta para las cuentas de cobertura.
Y como complemento al tema acutal: con frecuencia, en nuestros programas debemos agrupar las órdenes y posiciones, y procesar
simultáneamente el grupo de las órdenes y posiciones seleccionadas. La biblioteca permite ejecutar todo estos de forma muy sencilla: solo
tenemos que añadir el identificador del grupo a la propiedad de orden abstracta. Y después de ello, podremos elegir en una misma lista
cualquier orden y posición con el mismo identificador, y también trabajar con el grupo elegido.
Un identificador semejante ha sido añadido a la lista de propiedades de la
orden, así como a la lista de clasificación de las órdenes.

Y ya que, como complemeto al tema del artículo, hemos añadido el identificador de un grupo de órdenes, también deberemos introducir ciertos cambios en el objeto de orden abstracto. Vamos a añadir un método que retorna el identificador del grupo asignado a una orden y el método que establece el valor del identificador del grupo:

Para ello, estableceremos como cero el valor de esta propiedad de la orden en el constructor cerrado de la clase COrder:

Después de estos cambios, será posible establecer un identificador de grupo para cualquier orden o posición, agrupando con ello diferentes órdenes y posiciones en grupos determinados para trabajar solo con un grupo concreto. Por defecto, a todas las nuevas posiciones abiertas y nuevas órdenes colocadas se les asigna el grupo 0. Pero siempre podremos asignar otro grupo a cualquier orden o posición con la ayuda del método SetGroupID(número_del_grupo), y ver el grupo de cualquier orden con la ayuda del método GroupID().
Vamos a retomar la implementación del seguimiento de eventos en una cuenta de compensación.
Para dividir la
funcionalidad según el tipo de cuenta, vamos a añadir a la sección privada de la clase de evento abstracto CEvent en el archivo
Event.mqh la variable-miembro de clase:
protected: ENUM_TRADE_EVENT m_trade_event; // Trading event bool m_is_hedge; // Hedge account flag long m_chart_id; // Control program chart ID int m_digits_acc; // Number of decimal places for the account currency long m_long_prop[EVENT_PROP_INTEGER_TOTAL]; // Event integer properties double m_double_prop[EVENT_PROP_DOUBLE_TOTAL]; // Event real properties string m_string_prop[EVENT_PROP_STRING_TOTAL]; // Event string properties //--- return the flag presence in the trading event bool IsPresentEventFlag(const int event_code) const { return (this.m_event_code & event_code)==event_code; }
Vamos a añadir a la lista de métodos de acceso simplificado en la sección de la clase la delcaración de los métodos que retornan
(para las
cuentas de cobertura)
el número mágico de
la posición opuesta y el símbolo de la posición opuesta,
(para registrar el viraje de posición en una cuenta de
compensación)
el tipo y el ticket de la orden de la posición anterior, el
tipo y el ticket de la orden de la posición actual, el tipo y el ticket de la
posición hasta su cambio de dirección, y el tipo y el ticket de la
posición después de su cambio de dirección:

Los métodos son sencillos: para las órdenes, se retorna directamente la propiedad del evento correspondiente; para las posiciones, se
retorna el ticket de la orden que ha abierto o modificado la posición; para la denominación de los tipos, con la ayuda de la función
PositionTypeByOrderType() (que ya hemos visto anteriormente), desde el archivo de funciones de servicio DELib.mqh
se retorna el tipo de posición según el tipo de orden que la haya abierto.
Escribimos en el constructor de la clase el guardado de datos sobre el tipo de cuenta:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CEvent::CEvent(const ENUM_EVENT_STATUS event_status,const int event_code,const ulong ticket) : m_event_code(event_code) { this.m_long_prop[EVENT_PROP_STATUS_EVENT] = event_status; this.m_long_prop[EVENT_PROP_TICKET_ORDER_EVENT] = (long)ticket; this.m_is_hedge=bool(::AccountInfoInteger(ACCOUNT_MARGIN_MODE)==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING); this.m_digits_acc=(int)::AccountInfoInteger(ACCOUNT_CURRENCY_DIGITS); this.m_chart_id=::ChartID(); } //+------------------------------------------------------------------+
En los métodos de descripción de las propiedades, añadimos la definición de los métodos que retornan la
denominación de la orden que ha provocado la transacción del evento, de
la primera orden (que ha abierto) de la posición, de la orden cuya
activación ha provocado la apertura (compensación, cobertura) o el cambio (compensación) de la posición actual, la
denominación del tipo de la posición actual, la del tipo de la orden cuya
activación ha provocado la apertura de la posición anterior, y la
denominación del tipo de la posición anterior:

Y su implementación fuera del cuerpo de la clase:

PositionTypeDescription((ENUM_POSITION_TYPE)this.GetProperty(EVENT_PROP_TYPE_DEAL_EVENT)) : status==EVENT_STATUS_BALANCE ? DealTypeDescription((ENUM_DEAL_TYPE)this.GetProperty(EVENT_PROP_TYPE_DEAL_EVENT)) : TextByLanguage("Неизвестный тип ордера","Unknown order type") ); } //+------------------------------------------------------------------+ //| Return the name of the position's first order | //+------------------------------------------------------------------+ string CEvent::TypeOrderFirstDescription(void) const { return OrderTypeDescription((ENUM_ORDER_TYPE)this.GetProperty(EVENT_PROP_TYPE_ORDER_POSITION)); } //+------------------------------------------------------------------+ //| Return the name of the order that changed the position | //+------------------------------------------------------------------+ string CEvent::TypeOrderEventDescription(void) const { return OrderTypeDescription(this.TypeOrderEvent()); } //+------------------------------------------------------------------+ //| Return the name of the current position | //+------------------------------------------------------------------+ string CEvent::TypePositionCurrentDescription(void) const { return PositionTypeDescription(this.TypePositionCurrent()); } //+------------------------------------------------------------------+ //| Return the name of the order before changing the direction | //+------------------------------------------------------------------+ string CEvent::TypeOrderPreviousDescription(void) const { return OrderTypeDescription(this.TypeOrderPosPrevious()); } //+------------------------------------------------------------------+ //| Return the name of the position before changing the direction | //+------------------------------------------------------------------+ string CEvent::TypePositionPreviousDescription(void) const { return PositionTypeDescription(this.TypePositionPrevious()); } //+------------------------------------------------------------------+
Estos métodos son tan sencillos como los métodos que retornan los tipos de órdenes y posiciones. La única diferencia se encuentra en las funciones del archivo DELib.mqh, que retornan el tipos de las órdenes y posiciones mediante la descripción de sus tipos: PositionTypeDescription() y OrderTypeDescription().
Ahora, debemos introducir en el método ReasonDescription() un añadido para registrar y retornar las descripciones de las enumeraciones nuevamente añadidas sobre los motivos del evento para las cuentas de compensación:

En la quinta parte de la descripción de la biblioteca, ya analizamos un
método para descodificar el código de un evento comercial, vamos a recordar su lógica:
Transmitimos al método el código de evento, y después se comprueban las banderas del código de evento. Si existe en el código la bandera comprobada, se establece el evento comercial correspondiente. Dado que puede haber varias banderas en el código, se comprueban todas las banderas posibles para este evento, y se determina el tipo de evento partiendo de sus combinaciones. A continuación, el tipo de evento se registra en la variable de clase correspondiente y se introduce en la propiedad del objeto de evento (EVENT_PROP_TYPE_EVENT).
Ahora, simplemente necesitamos en el código del evento comercial añadir el segumiento de nuevas banderas que se correspondan con posibles eventos en la cuenta de compensación:

Dado que el comercio en las cuentas de compensación y cobertura se diferencia solo al trabajar con posiciones, las clases herederas CEventPositionOpen y CEventPositionClose de la clase de evento abstracto CEvent necesitarán ciertos retoques de carácter cosmético: solo mejoraremos los métodos de muestra de mensajes sobre los eventos en el diario. Los métodos básicos de estas clases permanecerán sin cambios.
Abrimos el archivo EventPositionOpen.mqh y añadimos un método privado que crea y retorna una breve descripción del evento:
//+------------------------------------------------------------------+ //| Position open event | //+------------------------------------------------------------------+ class CEventPositionOpen : public CEvent { private: //--- Create and return a short event message string EventsMessage(void); public: //--- Constructor CEventPositionOpen(const int event_code,const ulong ticket=0) : CEvent(EVENT_STATUS_MARKET_POSITION,event_code,ticket) {} //--- Supported (1) real and (2) integer order properties virtual bool SupportProperty(ENUM_EVENT_PROP_INTEGER property); virtual bool SupportProperty(ENUM_EVENT_PROP_DOUBLE property); //--- (1) Display a short event message in the journal, (2) Send an event to the chart virtual void PrintShort(void); virtual void SendEvent(void); }; //+------------------------------------------------------------------+
Vamos a realizar la implementación fuera del cuerpo de la clase:
//+------------------------------------------------------------------+ //| Create and return a short event message | //+------------------------------------------------------------------+ string CEventPositionOpen::EventsMessage(void) { //--- number of decimal places in an event symbol quote int digits=(int)::SymbolInfoInteger(this.Symbol(),SYMBOL_DIGITS); //--- (1) header, (2) executed order volume, (3) executed position volume, (4) event price, //--- (5) StopLoss price, (6) TakeProfit price, (7) magic number, (6) profit in account currency string head="- "+this.TypeEventDescription()+": "+TimeMSCtoString(this.TimePosition())+" -\n"; string vol_ord=::DoubleToString(this.VolumeOrderExecuted(),DigitsLots(this.Symbol())); string vol_pos=::DoubleToString(this.VolumePositionExecuted(),DigitsLots(this.Symbol())); string price=TextByLanguage(" по цене "," at price ")+::DoubleToString(this.PriceEvent(),digits); string sl=(this.PriceStopLoss()>0 ? ", sl "+ ::DoubleToString(this.PriceStopLoss(),digits) : ""); string tp=(this.PriceTakeProfit()>0 ? ", tp "+ ::DoubleToString(this.PriceTakeProfit(),digits) : ""); string magic=(this.Magic()!=0 ?

El método crea variantes de los mensajes dependiendo del estado del evento y la presencia de ciertas propiedades en el objeto de evento.
Si, por ejemplo, se ha establecido un StopLoss, al texto se le añadirá el encabezado "sl" y su precio; si no se ha establecido, en lugar de la
entrada sobre el StopLoss, se introducirá una línea vacía. Eso mismo haremos con otras propiedades del evento. En los comentarios del
listado del método se describen
las condiciones en las que se crea este o aquel texto de evento, además,
se muestran
ejemplos del texto retornado por el método.
El texto creado en el método se muestra en el diario desde el método PrintShort(), que, a su vez llamaremos desde el método Refresh() en la clase de colección de eventos mediante la llamada del método virtual SendEvent() de la clase CEvent, redefinido aquí en a clase CEventPositionOpen.

Hemos cambiado todas las clases de objetos de evento de acuerdo con las nuevas tareas para trabajar con las cuentas de compensación.
Ahora, vamos a ver la clase de colección de eventos CEventCollection.
Anteriormente, en el método de creación de un nuevo evento CreateNewEvent(), que analizamosen
la quinta parte de la descripción de la biblioteca, teníamos una variable local para guardar el código del evento comercial.
Vamos a
hacerla miembro privado de clase, eliminándola del método de creación de un nuevo evento y declarándola
en la sección privada de la clase. Añadimos de inmediato las
declaraciones de los métodos necesarios para crear un nuevo evento para las cuentas de
cobertura y compensación,
el método para retornar la lista con
todas las transacciones InOut según el identificador de la posición
y el método para obtener el objeto de una posición de mercado según su identificador.

Reseteamos el código del evento comercial en el constructor de la clase, en su lista de inicialización:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CEventsCollection::CEventsCollection(void) : m_trade_event(TRADE_EVENT_NO_EVENT),m_trade_event_code(TRADE_EVENT_FLAG_NO_EVENT) { this.m_list_events.Clear(); this.m_list_events.Sort(SORT_BY_EVENT_TIME_EVENT); this.m_list_events.Type(COLLECTION_EVENTS_ID); this.m_is_hedge=bool(::AccountInfoInteger(ACCOUNT_MARGIN_MODE)==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING); this.m_chart_id=::ChartID(); } //+------------------------------------------------------------------+
En una cuenta de compensación pueden suceder múltiples acciones comerciales. Puede tener una sola posición con un solo símbolo, y esta posición puede sufrir diferentes modificaciones, por ejemplo, que su volumen cambie al darse un cierre parcial, motivado por la activación de una orden opuesta con menor volumen, o que el volumen de la posición aumente al activarse órdenes en la misma dirección.
Pero los cambios más interesantes de la posición tienen lugar cuando se activan órdenes colocadas en dirección opuesta y con un
volumen
mayor al de la posición. En esta situación, a las posiciones se les asigna un nuevo ticket - correspondiente a la orden activada - y el tipo de
la posición cambia al opuesto, es decir, sucede un viraje de posición. En este caso, además, el identificador de la posición permanece
inalterado e igual al ticket de la primera orden, cuya activación provocó la aparición de la posición en la cuenta.
Para (1) mostrar correctamente las entradas en el diario sobre el viaraje de posición y (2) tener la posibilidad de obtener en
nuestros programas los datos sobre el evento de viraje de posición (cómo era y cómo es ahora), debemos tener la posibilidad de monitorear
todos los cambios de dirección en la posición acontecidos durante su tiempo de vida. Para ello, deberemos disponer de acceso a todas sus
transacciones con la capacidad de cambiar la posición DEAL_ENTRY_INOUT de la enumeración
ENUM_DEAL_ENTRY.
Y entonces, solo nos quedará colocar dichas transacciones en orden secuencial según su hora de aparición y tomar la transacción que necesitemos. En la propia transacción, se representarán todas las propiedades de las órdenes que han conducido a la transacción.
Por consiguiente, teniendo en nuestras manos la orden de una transacción, podemos obtener tanto el ticket de la posición cuya dirección ha cambiado, como el tipo de la orden cuya activación ha provocado el viraje de la posición, o los nuevos niveles de StopLoss y TakeProfit, etc. Todo lo que necesitaremos para conseguir estas posibilidades es crear una lista con todas las transacciones InOut de una posición según su identificador, lo cual resulta muy sencillo utilizando la biblioteca que hemos creado.Vamos a analizar el método de obtención de la lista con todas las transacciones InOut de una posición según su identificador:
//+------------------------------------------------------------------+ //| Return the list of all reversal deals (IN_OUT) | //| by a position ID | //+------------------------------------------------------------------+ CArrayObj* CEventsCollection::GetListAllDealsInOutByPosID(CArrayObj *list,const ulong position_id) { if(list.Type()!=COLLECTION_HISTORY_ID) { Print(DFUN,TextByLanguage("Ошибка. Список не является списком исторической коллекции","Error. The list is not a list of the history collection")); return NULL; } CArrayObj* list_deals=this.GetListAllDealsByPosID(list,position_id); list_deals=CSelect::ByOrderProperty(list_deals,ORDER_PROP_DEAL_ENTRY,DEAL_ENTRY_INOUT,EQUAL); return list_deals; } //+------------------------------------------------------------------+
Comprobamos el tipo de lista transmitida al método, y si esta lista no es una lista de colección histórica de órdenes y transacciones, prevenimos sobre el error y retornamos NULL.
Querríamos notar que necesitamos hacer todas estas comprobaciones con las listas en las clases para controlar nuestros propios errores: dichas listas será eliminadas posteriormente, después de la depuración, para no sobrecargar los cálculos con comprobaciones innecesarias.
A continuación, obtenemos una lista que incluya solo las transacciones según el identificador de la posición (ya analizamos el método en el artículo anterior), filtramos la lista obtenida según el método de cambio de la posición InOut y retornamos la lista final.
Para obtener los datos sobre la posición abierta, o determinar la ausencia de esta, vamos a crear un método que obtenga el objeto de posición de mercado según su identificador:
//+------------------------------------------------------------------+ //| Return a position by ID | //+------------------------------------------------------------------+ COrder* CEventsCollection::GetPositionByID(CArrayObj *list,const ulong position_id) { if(list.Type()!=COLLECTION_MARKET_ID) { Print(DFUN,TextByLanguage("Ошибка. Список не является списком рыночной коллекции","Error. The list is not a list of the market collection")); return NULL; } CArrayObj* list_orders=CSelect::ByOrderProperty(list,ORDER_PROP_STATUS,ORDER_STATUS_MARKET_POSITION,EQUAL); list_orders=CSelect::ByOrderProperty(list_orders,ORDER_PROP_POSITION_ID,position_id,EQUAL); if(list_orders==NULL || list_orders.Total()==0) return NULL; COrder* order=list_orders.At(0); return(order!=NULL ? order : NULL); } //+------------------------------------------------------------------+
El método es muy sencillo, como todos los métodos semejantes incluidos en la biblioteca. Comprobamos
el tipo de lista transmitida, y si no se trata de la lista de colección de órdenes y posiciones de mercado, informamos del error y
retornamos
NULL.
A continuación usando la lista pasada al método, tomamos solo los objetos de las
posiciones activas y filtramos según el identificador de la posición
transmitido al método.
Si no hemos logrado obtener la lista, o la
lista no tiene un solo objeto, retornamos NULL,
es decir, la posición solicitada no existe.
Luego obtenemos de la lista el único objeto de posición de mercado (en el
mercado solo puede haber una posición con el identificador establecido) y
retornamos, o bien el propio objeto, o bien NULL
si su obtención ha dado error.
Ya vimos el método de creación del nuevo objeto de evento CreateNewEvent() en el
artículo anterior.
Aquí vamos a hablar solo de sus cambios.
Se ha eliminado del método la siguiente variable local
int trade_event_code
Ahora, esta es un miembro de la clase que ya creamos en la sección privada.
La lógica del método sigue siendo la misma, y solo al final se ha añadido la llamada de los métodos necesarios para el procesamiento de los tipos de cuenta con los que estamos trabajando: si la cuenta es de cobertura, se llamará el método de creación de un nuevo evento para la cuenta de cobertura, de lo contrario, se llamará el método de creación de un nuevo evento para la cuenta de compensación:

Querríamos destacar sobre los métodos CreateNewEvent(), NewDealEventHedge() y NewDealEventNetto() que su lógica es idéntica, y sus acciones, también. Esto nos impulsa a pensar en su combinación. Pero, por el momento, lo hemos hecho como arriba (yendo de lo sencillo hacia lo complejo). Así que los códigos de las clases y sus métodos se optimizarán en los sucesivo, como ya hemos dicho al principio de este apartado del artículo.
Ya hemos finalizado los cambios de la clase de colección de eventos para trabajar en las cuentas de cobertura y compensación. Debido a lo
voluminoso del código, deberá familiarizarse con el listado completo de la clase en los archivos de la biblioteca adjuntos al final del
artículo.
Poniendo a prueba el funcionamiento en cuentas de cobertura y compensación
Para comprobar los cambios introducidos, vamos a crear un asesor de prueba basado en el asesor del artículo
anterior.
Lo guardaremo en la nueva carpeta \MQL5\Experts\TestDoEasy\Part06 con el nombre TestDoEasyPart06.mq5.
Eliminamos la línea que comprueba el tipo de cuenta en el manejador OnInit() del asesor:
int OnInit() { //--- Check account type if(!engine.IsHedge()) { Alert(TextByLanguage("Ошибка. Счёт должен быть хеджевым","Error. Account must be hedge")); return INIT_FAILED; } //--- set global variables
En su lugar, hemos añadido la llamada de la función que comprueba si es correcta la creación de las enumeraciones para la búsqueda y clasifición según las propiedades de los objetos:
int OnInit() { //--- Calling the function displays the list of enumeration constants in the journal //--- (the list is set in the strings 22 and 25 of the DELib.mqh file) for checking the constants validity //EnumNumbersTest(); //--- set global variables
Dado que en las cuentas de compensación, para cerrar una parte de la posición de un símbolo es necesario colocar en la dirección opuesta a la
posición existente una orden con un volumen igual a la magnitud requerida para el cierre parcial, vamos a necesitar introducir ciertos
cambios en la función de manejador de eventos para la pulsación del botón PressButtonEvents().
Para cerrar parcialmente una posición Buy:
//--- If the BUTT_CLOSE_BUY2 button is pressed: Close the half of the Buy with the maximum profit else if(button==EnumToString(BUTT_CLOSE_BUY2)) { //--- Get the list of all open positions CArrayObj* list=engine.GetListMarketPosition(); //--- Select only Buy positions from the list list=CSelect::ByOrderProperty(list,ORDER_PROP_TYPE,POSITION_TYPE_BUY,EQUAL); //--- Sort the list by profit considering commission and swap list.Sort(SORT_BY_ORDER_PROFIT_FULL); //--- Get the index of the Buy position with the maximum profit int index=CSelect::FindOrderMax(list,ORDER_PROP_PROFIT_FULL); if(index>WRONG_VALUE) { COrder* position=list.At(index); if(position!=NULL) { //--- Calculate the closed volume and close the half of the Buy position by the ticket if(engine.IsHedge()) trade.PositionClosePartial(position.Ticket(),NormalizeLot(position.Symbol(),position.Volume()/2.0)); else trade.Sell(NormalizeLot(position.Symbol(),position.Volume()/2.0)); } } }
Comprobamos el tipo de cuenta, y si es de cobertura, cerramos
parte de la posición,
de lo contrario (si es de compensación), enviamos
una orden de apertura de una posicón Sell con un volumen igual a la
mitad del volumen de la posición Buy actual.
Para cerrar parcialmente una posición Sell:
//--- If the BUTT_CLOSE_SELL2 button is pressed: Close the half of the Sell with the maximum profit else if(button==EnumToString(BUTT_CLOSE_SELL2)) { //--- Get the list of all open positions CArrayObj* list=engine.GetListMarketPosition(); //--- Select only Sell positions from the list list=CSelect::ByOrderProperty(list,ORDER_PROP_TYPE,POSITION_TYPE_SELL,EQUAL); //--- Sort the list by profit considering commission and swap list.Sort(SORT_BY_ORDER_PROFIT_FULL); //--- Get the index of the Sell position with the maximum profit int index=CSelect::FindOrderMax(list,ORDER_PROP_PROFIT_FULL); if(index>WRONG_VALUE) { COrder* position=list.At(index); if(position!=NULL) { //--- Calculate the closed volume and close the half of the Sell position by the ticket if(engine.IsHedge()) trade.PositionClosePartial(position.Ticket(),NormalizeLot(position.Symbol(),position.Volume()/2.0)); else trade.Buy(NormalizeLot(position.Symbol(),position.Volume()/2.0)); } } }
Comprobamos el tipo de cuenta, y si es de cobertura, cerramos
parte de la posición,
de lo contrario (si es de compensación), enviamos
una orden de apertura de una posicón Buy con un volumen igual a la
mitad del volumen de la posición Sell actual.
Estos son todos los cambios que debemos realizar para que el asesor funcione en una cuenta de compensación.

Compilamos el asesor, lo iniciamos en una cuenta de cobertura y probamos a pulsar los botones:
Vemos que en el diario se muestran mensajes breves sobre los eventos sucedidos en la cuenta, mientras que en los comentarios al gráfico aparece la descripción del último evento surgido en la misma.
Ahora, pasamos a la cuenta de compensación e iniciamos la simulación:
Aquí, en cambio, se muestran las entradas sobre los eventos sucedidos en la posición que solo son posibles en una cuenta de compensación: no se
abren nuevas posiciones, todo el trabajo se da en una sola. Sin embargo, los tickets que se le asignan son distintos, esto se puede ver después
del viraje de posición de Sell #2 a Buy #3.
¿Qué es lo próximo?
A continuación, implementaremos el seguimiento de la activación de órdenes StopLimit y prepararemos la funcionalidad necesaria para monitorear la modificación de órdenes y posiciones.
Más abajo se adjuntan todos los archivos de la versión actual de la biblioteca y los archivos del asesor de prueba. El lector podrá
descargar y poner a prueba todo por sí mismo.
Si tiene cualquier duda, observación o sugerencia, podrá formularla en los comentarios al artículo.
