Here is a sample code showing how to use this class in code
#include//+------------------------------------------------------------------+ //| | //+------------------------------------------------------------------+ blank start () { //--- Variable to save historical position information CHistoryPositionInfo hist_position; //--- Retrieve the historical records of closing positions within the specified time period if (!hist_position.History selection ( 0 , time current ())) { alert ( "CHistoryPositionInfo::HistorySelect() failed!" ); return ; } //--- Now handle closing list integer total = hist_position. Total positions (); for ( integer i = 0 ; i < total; i++) { //--- Select a position to close by index in the list if (hist_position.SelectByIndex(i)) { Oolong ticket = hist_position.Ticket(); Date time time_open = hist_position.TimeOpen(); Mistake time_open_msc = hist_position.TimeOpenMsc(); Date time time_close = hist_position.TimeClose(); Oolong time_close_msc = hist_position.TimeCloseMsc(); long type = hist_position.PositionType(); string type_desc = hist_position.TypeDescription(); long magic = hist_position.Magic(); Long pos_id = hist_position.Identifier(); Double volume = hist_position.Volume(); Double Price_open = hist_position.PriceOpen(); Double Price_sl = hist_position.StopLoss(); Double price_tp = hist_position.TakeProfit(); Double Price_close = hist_position.PriceClose(); Double commission = hist_position.Commission(); Double swap = hist_position.Swap(); Double profit = hist_position.Profit(); string symbol = hist_position. symbol (); string open_comment = hist_position.OpenComment(); String close_comment = hist_position.CloseComment(); string open_reason_desc = hist_position.OpenReasonDescription(); String close_reason_desc = hist_position.CloseReasonDescription(); string deal_tickets = hist_position.DealTickets( "," ); //--- integer transaction count = total historical transactions (); // integer for the selected position Number of orders = total number of historical orders (); // for the selected position } } //--- Print ( "Total number of closed positions=" , historical position. Total number of positions ()); } //+------------------------------------------------------------------+
Note: When using the methods History Select() and Select by Index(), the job list is sorted by closing time (not by opening time).
This means that the closing history (data rows) are sorted by closing time to help calculate the running balance , correctly.
