Bibliothek für ein leichtes und schnelles Entwickeln vom Programmen für den MetaTrader (Teil XXXII): Schwebende Handelsanfragen - Orders unter bestimmten Bedingungen platzieren
Inhalt
Im vorherigen Artikel haben wir die Möglichkeit hinzugefügt, Handelsanfragen zu vordefinierten Bedingungen zu senden. Wenn eine bestimmte Bedingung (oder eine Reihe von Bedingungen) eintritt, wird ein Handelsauftrag zur Eröffnung einer Position gesendet. Es kann mehrere Bedingungen in verschiedenen Kombinationen aus den Listen der Konto-, Symbol- und Ereignisstatusbedingungen geben.
Handelsaufträge werden mit schwebenden Handelsanfragen versandt, wenn alle im Objekt der schwebenden Anfrage festgelegten Bedingungen erfüllt sind.
In diesem Artikel setzen wir die Entwicklung des Konzepts fort und schaffen die Funktionen, die es ermöglicht, mit Hilfe von schwebenden Anfragen mit allen Bedingungen, die für die Platzierung einer schwebenden Anfrage notwendig sind, um Pending-Orders zu platzieren.
Konzept
Das Objekt der schwebenden Anfrage enthält das Array, in dem alle seine Aktivierungsbedingungen gespeichert sind. Die Klasse zur Handelsverwaltung (d.h. ihr Timer) ermöglicht die ständige Einsicht in die Liste der schwebenden Handelsanfragen. Wenn es an der Zeit ist, eine schwebende Handelsanfrage zu aktivieren (alle vordefinierten Aktivierungsbedingungen sind erfüllt), wird ein Handelsauftrag an den Server gesendet. Seine Parameter werden von der ausgelösten schwebenden Anfrage festgelegt.
Um Positionen zu eröffnen, müssen wir nur das Auftreten bestimmter Bedingungen kontrollieren. Sobald sie eintreten, wird der Handelsauftrag zur Eröffnung einer Position an den Server gesendet.
Es gibt jedoch eine Komplikation bei der Platzierung von Pending-Orders unter Verwendung der schwebenden Anfrageobjekte: Ein Auftrag wird in einem Abstand zum Preis platziert, während eine Position zum entsprechenden aktuellen Preis festgelegt wird.
Um unter bestimmten Bedingungen mit der Platzierung von ausstehenden Bestellungen arbeiten zu können, müssen wir daher auch die Entfernung der Platzierung der ausstehenden Bestellung berücksichtigen. Daraus ergibt sich eine Frage: Beim Erstellen einer schwebenden Anfrage geben wir den Abstand einer zukünftigen Pending-Order an. ABER... ab welchem Preis? Von dem Preis, der zum Zeitpunkt einer hängigen Anfrage vorliegt? Oder von dem Preis, der zum Zeitpunkt der Erfüllung aller Bedingungen, die im Objekt der Anfrage für ihre Aktivierung festgelegt wurden, vorhanden ist? Schließlich kann sich der Preis zum Zeitpunkt der Erfüllung aller Bedingungen weit von der Ebene entfernen, auf der die schwebende Anfrage erstellt wurde, während wir den zukünftigen Preis nur in einem Fall kennen können — wenn die einzige Aktivierungsbedingung einer schwebenden Anforderung ein bestimmter Preiswert ist. In anderen Fällen ist der zukünftige Preis, von dem wir eine Order festlegen müssen, unbekannt.
Machen wir es so: Wenn wir eine schwebende Anfrage erstellen, geben wir den Abstand der Pending-Order an. Wir können den Abstand immer mit Hilfe der Differenz zwischen dem aktuellen Preis zum Zeitpunkt der Erstellung einer schwebenden Anfrage (der aktuelle Ask- oder Bid-Preis wird in den Objekteigenschaften in Abhängigkeit von der zukünftigen Auftragsrichtung festgelegt) und dem Preis der Platzierung einer schwebenden Anfrage (ebenfalls in den Objekteigenschaften der ausstehenden Anfrage festgelegt) anzeigen. Mit anderen Worten, wir sind in der Lage, einen neuen Preis für eine schwebende Anfrage zu einem beliebigen Preiswert zum Zeitpunkt der Aktivierung der schwebenden Anfrage zu berechnen oder den beim Erstellen der schwebenden Anfrage angegebenen Preis zu belassen.
Im ersten Fall wird der Auftragspreis im Verhältnis zum aktuellen Preis zum Zeitpunkt der Aktivierung der schwebenden Anfrage neu berechnet, während im zweiten Fall ein Handelsauftrag zur Platzierung einer schwebenden Anfrage im Verhältnis zu dem Preis, auf dem die schwebende Anfrage basiert, an den Server gesendet wird. Durch diese Option wird der Preis angepasst, wenn er während des Wartens auf die Aktivierung der schwebenden Anfrage ungültig wird.
Umsetzung
In der Datei PendRequest.mqh, d.h. im 'private' Abschnitt der abstrakten Objektklasse CPendRequest der schwebenden Anfrage, fügen wir die Klassenvariable zur Speicherung des Flags zur Verschiebung des Referenzpunktes für den Abstand der schwebenden Anfrage nach dem Preis:
//+------------------------------------------------------------------+ //| Abstract pending trading request class | //+------------------------------------------------------------------+ class CPendRequest : public CBaseObj { private: MqlTradeRequest m_request; // Trade request structure CPause m_pause; // Pause class object bool m_follow; // The flag of the pending order distance reference point following the price /* Data on a pending request activation in the array:
Wenn die Variable true ist, wird der Auftragspreis relativ zum aktuellen Preis zum Zeitpunkt der Aktivierung der schwebenden Anfrage neu berechnet. Andernfalls wird die Pending-Order auf den in den Eigenschaften des Objekts für schwebende Anfragen festgelegten Preis gesetzt und angepasst, falls der Auftragspreis aufgrund einer Änderung des aktuellen Preises im Verhältnis zum Preis der schwebenden Anfrage ungültig wird.
Im 'protected' Abschnitt der Klasse deklarieren wir die Methode der Platzierung von der Pending-Order zum Preis gemäß der Veränderung:
//--- Return the number of decimal places of a controlled property int DigitsControlledValue(const uint index) const; //--- Set a new value changed by the shift (+/-) for all order prices void SetAllMqlPrices(const double shift); public:
Deklarieren wir die Methode zur Anpassung der Preise für Pending-Orders im Verhältnis zum aktuellen Preis im Block der Methoden für einen vereinfachten Zugriff auf die Eigenschaften des Anforderungsobjekts im 'public' Teil der Klasse, und wir schreiben die Methoden zur Platzierung neuer Order-Preise in die Eigenschaften des schwebenden Anfrageobjekts und die Methoden zum Setzen/Empfangen des Flags für den Bezugspunkt des Order-Preises nach dem Preis:

Wir setzen im Klassenkonstruktor das Flag des Bezugspunktes für den Orderabstand nach dem Preis:
//+------------------------------------------------------------------+ //| Constructor | //+------------------------------------------------------------------+ CPendRequest::CPendRequest(const ENUM_PEND_REQ_STATUS status, const uchar id, const double price, const ulong time, const MqlTradeRequest &request, const int retcode) { this.CopyRequest(request); this.m_is_hedge=#ifdef __MQL4__ true #else bool(::AccountInfoInteger(ACCOUNT_MARGIN_MODE)==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING) #endif; this.m_digits=(int)::SymbolInfoInteger(this.GetProperty(PEND_REQ_PROP_MQL_REQ_SYMBOL),SYMBOL_DIGITS); int dg=(int)DigitsLots(this.GetProperty(PEND_REQ_PROP_MQL_REQ_SYMBOL)); this.m_digits_lot=(dg==0 ? 1 : dg); this.SetProperty(PEND_REQ_PROP_STATUS,status); this.SetProperty(PEND_REQ_PROP_ID,id); this.SetProperty(PEND_REQ_PROP_RETCODE,retcode); this.SetProperty(PEND_REQ_PROP_TYPE,this.GetProperty(PEND_REQ_PROP_RETCODE)>0 ? PEND_REQ_TYPE_ERROR : PEND_REQ_TYPE_REQUEST); this.SetProperty(PEND_REQ_PROP_TIME_CREATE,time); this.SetProperty(PEND_REQ_PROP_PRICE_CREATE,price); this.m_pause.SetTimeBegin(this.GetProperty(PEND_REQ_PROP_TIME_CREATE)); this.m_pause.SetWaitingMSC(this.GetProperty(PEND_REQ_PROP_WAITING)); ::ArrayResize(this.m_activated_control,0,10); this.m_follow=true; } //+------------------------------------------------------------------+
Implementieren wir die Methode zum Setzen neuer Werte für alle Orderpreise außerhalb des Klassenkörpers:
//+------------------------------------------------------------------+ //| Set a new value changed by the shift (+/-), | //| for all order prices (+/-) | //+------------------------------------------------------------------+ void CPendRequest::SetAllMqlPrices(const double shift) { this.SetMqlPrice(this.GetProperty(PEND_REQ_PROP_MQL_REQ_PRICE)-shift); if(this.GetProperty(PEND_REQ_PROP_MQL_REQ_SL)!=0) this.SetMqlSL(this.GetProperty(PEND_REQ_PROP_MQL_REQ_SL)-shift); if(this.GetProperty(PEND_REQ_PROP_MQL_REQ_TP)!=0) this.SetMqlTP(this.GetProperty(PEND_REQ_PROP_MQL_REQ_TP)-shift); if(this.GetProperty(PEND_REQ_PROP_MQL_REQ_STOPLIMIT)!=0) this.SetMqlStopLimit(this.GetProperty(PEND_REQ_PROP_MQL_REQ_STOPLIMIT)-shift); } //+------------------------------------------------------------------+
Die Methode erhält die Preisänderung, und die oben beschriebenen Methoden werden verwendet, um neue Preise in jeder Eigenschaft des schwebenden Anfrageobjekts festzulegen, die den Preistypen der schwebenden Anfragen entsprechen, die berechnet werden als (der aktuelle Wert dieser Eigenschaft minus des Abstandes).
Bei StopLoss-, TakeProfit- und StopLimit-Orderpreisen wird die Existenz des Preises vorläufig geprüft, und eine Änderung wird nur festgelegt, wenn der in den Eigenschaften des schwebenden Anfrageobjekts festgelegte Preis einen Wert ungleich Null hat.
Die Implementierung der Methode zur Anpassung der Preise einer aufgegebenen Pending-Order durch den aktuellen Preis zum Zeitpunkt der Aktivierung der ausstehenden Anfrage:
//+------------------------------------------------------------------+ //| Adjust order prices by the current price | //+------------------------------------------------------------------+ void CPendRequest::CorrectMqlPricesByCurrentPrice(const double price) { ENUM_ORDER_TYPE type=this.m_request.type; if(!this.m_follow || (type<ORDER_TYPE_BUY_LIMIT && type>ORDER_TYPE_SELL_STOP_LIMIT)) return; this.SetAllMqlPrices(this.PriceCreate()-price); } //+------------------------------------------------------------------+
Die Methode erhält den aktuellen Preis, zu dem die Pending-Order erteilt werden sollte. Wenn das Flag, dem Preis um den Bezugspunkt der Orderdistanz zu folgen, nicht gesetzt ist oder die Pending-Order nicht zur Handelsanforderungsstruktur des schwebenden Anfrageobjekts hinzugefügt wird, verlassen wir die Methode.
Wir rufen dann die oben beschriebene Methode zum Ändern aller Pending-Orders auf. Sie erhält den Abstand, der berechnet wird als Preis zum Zeitpunkt der Erstellung des schwebenden Anfrageobjekts minus dem aktuellen Preis, der an die Methode übergeben wird.
Kommen wir nun zu den Ergänzungen und Verbesserungen in der Datei PendReqControl.mqh mit der Klasse CPendReqControl für das Handelsmanagement.
Wir benennen die öffentlichen Methoden OpenPositionPending() und PlaceOrderPending() zum Erstellen schwebender Anfragen in CreatePReqPosition() bzw. CreatePReqOrder() um. Ich glaube, diese Methodennamen spiegeln die Idee dahinter (Erstellung einer ausstehenden Anforderung) genauer wider.
Den Argumenten der Methode CreatePReqOrder() fügen wir die Gruppen-ID hinzu:
//--- (1) Create a pending request (1) to open a position, (2) to place a pending order template<typename SL,typename TP> int CreatePReqPosition(const ENUM_POSITION_TYPE type, const double volume, const string symbol, const ulong magic=ULONG_MAX, const SL sl=0, const TP tp=0, const uchar group_id1=0, const uchar group_id2=0, const string comment=NULL, const ulong deviation=ULONG_MAX, const ENUM_ORDER_TYPE_FILLING type_filling=WRONG_VALUE); template<typename PS,typename PL,typename SL,typename TP> int CreatePReqOrder(const ENUM_ORDER_TYPE order_type, const double volume, const string symbol, const PS price_set, const PL price_limit=0, const SL sl=0, const TP tp=0, const ulong magic=ULONG_MAX, const uchar group_id1=0, const uchar group_id2=0, const string comment=NULL, const datetime expiration=0, const ENUM_ORDER_TYPE_TIME type_time=WRONG_VALUE, const ENUM_ORDER_TYPE_FILLING type_filling=WRONG_VALUE); //--- Set pending request activation criteria
Wir ergänzen auch bei der Behandlung die schwebenden Anfragen, die durch Aufträge erstellt werden:
//+------------------------------------------------------------------+ //| The handler of pending requests created by request | //+------------------------------------------------------------------+ void CTradingControl::OnPReqByRequestHandler(CPendRequest *req_obj,const int index) { //--- get the request structure and the symbol object a trading operation should be performed for MqlTradeRequest request=req_obj.MqlRequest(); CSymbol *symbol_obj=this.m_symbols.GetSymbolObjByName(request.symbol); if(symbol_obj==NULL || !symbol_obj.RefreshRates()) return; //--- Check the relevance of a pending request and exit to the external loop if the request is handled or an error occurs if(!this.CheckPReqRelevance(req_obj,request,index)) return; //--- Update relevant data on request activation conditions this.RefreshControlActualDatas(req_obj,symbol_obj); //--- If all pending request activation conditions are met if(req_obj.IsAllComparisonCompleted()) { //--- Set the attempt number in the request object req_obj.SetCurrentAttempt(uchar(req_obj.CurrentAttempt()+1)); //--- Adjust prices for a pending order relative to the current price and get the request again if(request.action==TRADE_ACTION_PENDING) { req_obj.CorrectMqlPricesByCurrentPrice(PositionTypeByOrderType(request.type)==POSITION_TYPE_BUY ? symbol_obj.AskLast() : symbol_obj.BidLast()); request=req_obj.MqlRequest(); } //--- Display the request activation message in the journal if(this.m_log_level>LOG_LEVEL_NO_MSG) { ::Print(CMessage::Text(MSG_LIB_TEXT_REQUEST_ACTIVATED)+(string)req_obj.ID()+":"); req_obj.PrintShort(); } //--- Depending on the type of action performed in the trading request switch(request.action) { //--- Opening/closing a position case TRADE_ACTION_DEAL : //--- If no ticket is present in the request structure - this is opening a position if(request.position==0) this.OpenPosition((ENUM_POSITION_TYPE)request.type,request.volume,request.symbol,request.magic,request.sl,request.tp,request.comment,request.deviation,request.type_filling); //--- If the ticket is present in the request structure - this is a position closure else this.ClosePosition(request.position,request.volume,request.comment,request.deviation); break; //--- Modify StopLoss/TakeProfit position case TRADE_ACTION_SLTP : this.ModifyPosition(request.position,request.sl,request.tp); break; //--- Close by an opposite one case TRADE_ACTION_CLOSE_BY : this.ClosePositionBy(request.position,request.position_by); break; //--- //--- Place a pending order case TRADE_ACTION_PENDING : this.PlaceOrder(request.type,request.volume,request.symbol,request.price,request.stoplimit,request.sl,request.tp,request.magic,request.comment,request.expiration,request.type_time,request.type_filling); break; //--- Modify a pending order case TRADE_ACTION_MODIFY : this.ModifyOrder(request.order,request.price,request.sl,request.tp,request.stoplimit,request.expiration,request.type_time,request.type_filling); break; //--- Remove a pending order case TRADE_ACTION_REMOVE : this.DeleteOrder(request.order); break; //--- default: break; } } } //+------------------------------------------------------------------+
Wenn der in der Struktur der Handelsanforderung der schwebenden Anfrage festgelegte Handelsoperationstyp "eine Pending-Order platzieren" ist, wird die Methode zur Anpassung des Preises,der Pending-Order aufgerufen, die in den Objekteigenschaften der Pending-Order festgelegt wurde. Infolgedessen werden die Preise für schwebende Anfragen im Anfrageobjekt entweder relativ zum aktuellen Preis angepasst oder nicht — dies hängt von dem Flag des Referenzpunktes für den Abstand der Pending-Order ab, der dem Preis im Anfrageobjekt folgt. Wir haben dieses Verhalten oben besprochen.
Lassen Sie uns die Methode zur Erstellung einer ausstehenden Anfrage zur Eröffnung einer Position etwas verbessern. Bei der Entwicklung mit der Copy-Paste-Methode habe ich einen Fehler gemacht — die Methode sollte den ganzzahligen Wert der ID der schwebenden Anfrage zurückgeben, während sie derzeit im Falle eines Fehlers falsch zurückgibt. Ändern wir ihn in WRONG_VALUE:

Die Methode wird in den Code-Kommentaren ausführlich beschrieben. Wir haben bereits eine ähnliche Methode zum Erstellen einer schwebenden Anfrage auf Eröffnung einer Position in Betracht gezogen, daher ist es nicht sinnvoll, hier darauf einzugehen. Wenn Sie Fragen haben, können Sie diese gerne in den Kommentaren stellen.
Wenn wir eine schwebende Anfrage erstellen, müssen wir den Preis zum Zeitpunkt ihrer Erstellung im Objekt der schwebenden Anfrage eintragen. Wir müssen für verschiedene Auftragsarten die jeweiligen Preise festlegen. Bei Kaufaufträgen ist es der aktuelle Ask, bei Verkaufsaufträgen der aktuelle Bid.
Dazu ändern wir die Methode CreatePendingRequest() zum Erstellen einer schwebenden Anfrage in der Datei Trading.mqh mit der Basisklasse des Handelsobjekts CTrading vor:
//+------------------------------------------------------------------+ //| Create a pending request | //+------------------------------------------------------------------+ bool CTrading::CreatePendingRequest(const ENUM_PEND_REQ_STATUS status, const uchar id, const uchar attempts, const ulong wait, const MqlTradeRequest &request, const int retcode, CSymbol *symbol_obj, COrder *order) { //--- Create a new pending request object depending on a request status CPendRequest *req_obj=NULL; double price=(PositionTypeByOrderType(request.type)==POSITION_TYPE_BUY ? symbol_obj.AskLast() : symbol_obj.BidLast()); switch(status) { case PEND_REQ_STATUS_OPEN : req_obj=new CPendReqOpen(id,price,symbol_obj.Time(),request,retcode); break; case PEND_REQ_STATUS_CLOSE : req_obj=new CPendReqClose(id,price,symbol_obj.Time(),request,retcode); break; case PEND_REQ_STATUS_SLTP : req_obj=new CPendReqSLTP(id,price,symbol_obj.Time(),request,retcode); break; case PEND_REQ_STATUS_PLACE : req_obj=new CPendReqPlace(id,price,symbol_obj.Time(),request,retcode); break; case PEND_REQ_STATUS_REMOVE : req_obj=new CPendReqRemove(id,price,symbol_obj.Time(),request,retcode); break; case PEND_REQ_STATUS_MODIFY : req_obj=new CPendReqModify(id,price,symbol_obj.Time(),request,retcode); break; default: req_obj=NULL; break; } if(req_obj==NULL) { if(this.m_log_level>LOG_LEVEL_NO_MSG) ::Print(DFUN,CMessage::Text(MSG_LIB_TEXT_FAILING_CREATE_PENDING_REQ)); return false; } //--- If failed to add the request to the list, display the appropriate message, //--- remove the created object and return 'false' if(!this.m_list_request.Add(req_obj)) { if(this.m_log_level>LOG_LEVEL_NO_MSG) ::Print(DFUN,CMessage::Text(MSG_LIB_TEXT_FAILING_CREATE_PENDING_REQ)); delete req_obj; return false; } //--- Fill in the properties of a successfully created object by the values passed to the method req_obj.SetTimeActivate(symbol_obj.Time()+wait); req_obj.SetWaitingMSC(wait); req_obj.SetCurrentAttempt(0); req_obj.SetTotalAttempts(attempts); if(order!=NULL) { req_obj.SetActualVolume(order.Volume()); req_obj.SetActualPrice(order.PriceOpen()); req_obj.SetActualStopLimit(order.PriceStopLimit()); req_obj.SetActualSL(order.StopLoss()); req_obj.SetActualTP(order.TakeProfit()); req_obj.SetActualTypeFilling(order.TypeFilling()); req_obj.SetActualTypeTime(order.TypeTime()); req_obj.SetActualExpiration(order.TimeExpiration()); } else { req_obj.SetActualVolume(request.volume); req_obj.SetActualPrice(request.price); req_obj.SetActualStopLimit(request.stoplimit); req_obj.SetActualSL(request.sl); req_obj.SetActualTP(request.tp); req_obj.SetActualTypeFilling(request.type_filling); req_obj.SetActualTypeTime(request.type_time); req_obj.SetActualExpiration(request.expiration); } //--- Display a brief description of a created pending request if(this.m_log_level>LOG_LEVEL_NO_MSG) { ::Print(CMessage::Text(MSG_LIB_TEXT_PEND_REQUEST_CREATED)," #",req_obj.ID(),":"); req_obj.PrintShort(); } //--- successful return true; } //+------------------------------------------------------------------+
Hier verwenden wir die Funktion der Definition des Positionstyps durch den Auftragstyp PositionTypeByOrderType(), um die Auftragsrichtung zu definieren. Im Falle eines Kaufauftrags verwenden wir den Ask-Preis, im Falle eines Verkaufsauftrags den Bid-Preis. Bei der Erstellung einer Pending-Order geben wir den erhaltenen Preis an seine Erstellungsmethode weiter.
Jetzt müssen wir nur noch den Zugriff auf die erstellte Funktionalität implementieren. Im 'public' Teil des Hauptobjekts CEngineder Bibliothek deklarieren wir die Methoden zum Erstellen von schwebenden Anfragen für alle Ordertypen :

Außerhalb des Klassenkörpers implementieren wir all diese Methoden und benennen gleichzeitig die Methoden zum Erstellen von schwebenden Anfragen zur Eröffnung von Positionen mit der Zeit (wir haben das bereits früher getan):

Hier geben die Methoden zum Erstellen der schwebenden Anfragen, die Pending-Orders platzieren, das Ergebnis der Methode zum Erstellen einer schwebenden Anfrage der Trading-Management-Klasse CTradingControl zurück, die die erforderlichen Typen der Pending-Orders erhält, die der Methode entsprechen, aus der die Pending-Anfrage erstellt wurde. Für MQL4 geben wir WRONG_VALUE zurück, da wir die Klasse für Objekte von Pending-StopLimit-Order für MQL4 nicht haben.
Dies sind alle Änderungen, die für die Platzierung von Pending-Orders unter Bedingungen mit schwebenden Handelsanfragen erforderlich sind.
Tests
Um den Test durchzuführen, verwenden wir den EA aus dem vorherigen Artikel und speichern ihn in \MQL5\Experts\TestDoEasy\ Part32\ unter dem Namen TestDoEasyPart32.mq5.
Alles, was wir noch hinzufügen müssen, ist die Kontrolle über die Zustände der Schaltflächen, die die Aktivierung der Schaltflächen für die Aktivierung der entsprechenden Schaltflächen zur Platzierung ausstehender Bestellungen verwalten. Wenn P oder T (Preis- und Zeitbedingung) in der Nähe des Buttons für die Platzierung ausstehender Aufträge gedrückt wird, wird ein solcher Auftrag nicht sofort platziert. Stattdessen wird eine schwebende Anfrage erstellt. Deren Aktivierung durch eine bestimmte Bedingung führt zur Platzierung der Pending-Order. Der Auftrag wird relativ zu dem Preis gesetzt, zu dem die schwebende Anfrage aktiviert wurde.
Fügen wir der Funktion, die das Drücken der Schaltflächen des Handelspanels des Test-EAs handhabt, zwei Variablen zur Speicherung der Werte Point() und Digits() des aktuellen Symbols sowie Handhabung beim Drücken der Schaltflächen des Handelspanels zur Erstellung von schwebenden Anfragen für das Platzieren aller Typen von Pending-Orders hinzu:

Die Codes der Tastenblöcke sind mit detaillierten Kommentaren versehen, so dass es keinen Sinn macht, hier darauf zu verweilen. Wenn Sie Fragen haben, können Sie diese gerne in den Kommentaren stellen.
Dies sind alle notwendigen Änderungen des Test-EAs.
Kompilieren Sie den EA und starten Sie ihn im Tester im visuellen Modus.
Aktivieren Sie einfach die Schaltflächen zum Erstellen schwebende Anfragen, um Pending-Orders zu platzieren, und sehen Sie, wie die schwebenden Anfragen ausgeführt werden:
Zuerst wurde eine schwebende Anfrage zum Platzieren einer Pending-Order nach Preis und Zeit erstellt, während die übrigen schwebenden Anfragen nur nach Zeit erstellt wurden. Wie wir sehen können, wurden alle schwebenden Anfragen beim Eintreten ihrer Aktivierungsbedingungen aktiviert: die erste — nach Preis und Zeit, während die folgenden — nach ihrer Aktivierungszeit aktiviert wurden. Alles funktioniert also wie geplant.
