Task: there are two iMA indicators. Need to find: how many bars have passed since the last crossing.
Algorithm: if this is the first run - use the first form of the CopyBuffer function
Call by the first position and the number of required elements
intCopyBuffer(
int indicator_handle, // indicator handleint buffer_num, // indicator buffer numberint start_pos, // start positionint count, // amount to copydouble buffer[] // target array to copy
);
copy 100 elements and search for the intersection. We print the number
of the bar and the opening time of the bar with the
intersection
for(int i=1; i<count-1; i++)
{
if((fast[i+1]<slow[i+1] && fast[i]>slow[i]) || (fast[i+1]>slow[i+1] && fast[i]<slow[i]))
{
Comment("Bars after the last iMA crossing: ",IntegerToString(i+1)," (",TimeToString(rates[i].time,TIME_DATE|TIME_MINUTES),")");
m_last_crossing=rates[i+2].time;
return;
}
}
Next time we use the third form
Call by the start and end dates of a required time interval
intCopyBuffer(
int indicator_handle, // indicator handleint buffer_num, // indicator buffer numberdatetime start_time, // start date and timedatetime stop_time, // end date and timedouble buffer[] // target array to copy
);
Counting of elements of copied data (indicator buffer with the index buffer_num) from the starting position is performed from the present to the past, i.e., starting position of 0 means the current bar (indicator value for the current bar). When copying the yet unknown amount of data, it is recommended to use a dynamic array as a buffer[]...
An example of how to create a handle to the MACD indicator. An example of how to get the MACD indicator values on the last three bars. Remember
the main rule: you need to create an indicator handle once (the best option is to create a handle in OnInit).
Hi Vladimir, thank you for your great effort, I have learned a lot from you MQL5 and I want to help you with the (PositionClosePartial) function and this code please look at it .. as it sometimes succeeds in closing a part and sometimes it fails and closes all deals in its use in hedging :
voidOnTradeTransaction(constMqlTradeTransaction &trans,
constMqlTradeRequest &request,
constMqlTradeResult &result)
{
//--- get transaction type as enumeration value ENUM_TRADE_TRANSACTION_TYPE type=trans.type;
ENUM_ACCOUNT_MARGIN_MODE AccountMargin = (ENUM_ACCOUNT_MARGIN_MODE)AccountInfoInteger(ACCOUNT_MARGIN_MODE);
if(AccountMargin==ACCOUNT_MARGIN_MODE_RETAIL_HEDGING)accofif=true;
//--- if transaction is result of addition of the transaction in historyif(type==TRADE_TRANSACTION_DEAL_ADD)
{
long deal_type =-1;
long deal_entry =-1;
double deal_volume =0.0;
string deal_symbol ="";
if(HistoryDealSelect(trans.deal))
{
deal_type =HistoryDealGetInteger(trans.deal,DEAL_TYPE);
deal_entry =HistoryDealGetInteger(trans.deal,DEAL_ENTRY);
deal_volume =HistoryDealGetDouble(trans.deal,DEAL_VOLUME);
deal_symbol =HistoryDealGetString(trans.deal,DEAL_SYMBOL);
}
elsereturn;
if(deal_entry==DEAL_ENTRY_OUT)
{
ulong PositionTicket=PositionGetInteger(POSITION_TICKET);
ulong deviation=ULONG_MAX;
switch((int)deal_type)
{
caseDEAL_TYPE_SELL:
if(Total(POSITION_TYPE_SELL) >0&& accofif)
m_trade.PositionClosePartial(PositionTicket,Lot,-1);
break;
caseDEAL_TYPE_BUY:
if(Total(POSITION_TYPE_BUY) >0&& accofif)
m_trade.PositionClosePartial(PositionTicket,Lot,-1);
break;

thank you very much Note: I searched a lot in the MQL5 library I have not found using PositionClosePartial and I hope you add this functionality to the library ... best wishes

When I need to close part of a position (on a hedge account) I use CTrade.PositionClosePartial

Open position every new candle.
First we define a new bar.
If this is a new bar - open a BUY position with a minimum volume.

An example of get values from the iStochastic indicator
Code: iStochastic get value.mq5
Do not forget the rules: create the indicator handle ONCE in OnInit, use CopyBuffer to get the data.
Result:

Error:
if you caught a transaction of a type 'DEAL_ENTRY_OUT', then there is ALREADY no position.
It is necessary to change the logic.
Note: I searched a lot in the MQL5 library
I have not found using PositionClosePartial and I hope you add this functionality to the library
