Documentation on MQL5: Standard Constants, Enumerations and Structures / Trade Constants / Trade Operation Types
- www.mql5.com
Trading is done by sending orders to open positions using the OrderSend() function, as well as to place, modify or delete pending orders. Each trade order refers to the type of the requested operation. Trading operations are described in the ENUM_TRADE_REQUEST_ACTIONS enumeration...
When PositionsTotal() returns one less.
for handling positions you can use this : (fast write up)
void OnTrade() { static int previous_open_positions = 0; int current_open_positions = PositionsTotal(); if(current_open_positions != previous_open_positions) { if(current_open_positions < previous_open_positions) // A position just got closed { previous_open_positions = current_open_positions; // some operations on last closed position. (or others in history.) } else // A position just got opened { previous_open_positions = current_open_positions; // some operations on last opened position. (or all open ones.) } } }
OnTrade event triggers on modifies, and orders execution/cancelling too. so the codes filters the calls, to only watch for a change in position lists. tweak that if u want
+------------------------------------------------------------------+ void OnTradeTransaction (const MqlTradeTransaction &trans, const MqlTradeRequest &request, const MqlTradeResult &result) { //--- get transaction type as enumeration value ENUM_TRADE_TRANSACTION_TYPE type=trans.type; //--- if transaction is result of addition of the transaction in history if(type==TRADE_TRANSACTION_DEAL_ADD) { long deal_ticket = 0; long deal_order = 0; long deal_time = 0; long deal_time_msc = 0; long deal_type = -1; long deal_entry = -1; long deal_magic = 0; long deal_reason = -1; long deal_position_id = 0; double deal_volume = 0.0; double deal_price = 0.0; double deal_commission = 0.0; double deal_swap = 0.0; double deal_profit = 0.0; string deal_symbol = ""; string deal_comment = ""; string deal_external_id = ""; if(HistoryDealSelect(trans.deal)) { deal_ticket = HistoryDealGetInteger(trans.deal, DEAL_TICKET); deal_order = HistoryDealGetInteger(trans.deal, DEAL_ORDER); deal_time = HistoryDealGetInteger(trans.deal, DEAL_TIME); deal_time_msc = HistoryDealGetInteger(trans.deal, DEAL_TIME_MSC); deal_type = HistoryDealGetInteger(trans.deal, DEAL_TYPE); deal_entry = HistoryDealGetInteger(trans.deal, DEAL_ENTRY); deal_magic = HistoryDealGetInteger(trans.deal, DEAL_MAGIC); deal_reason = HistoryDealGetInteger(trans.deal, DEAL_REASON); deal_position_id = HistoryDealGetInteger(trans.deal, DEAL_POSITION_ID); deal_volume = HistoryDealGetDouble(trans.deal, DEAL_VOLUME); deal_price = HistoryDealGetDouble(trans.deal, DEAL_PRICE); deal_commission = HistoryDealGetDouble(trans.deal, DEAL_COMMISSION); deal_swap = HistoryDealGetDouble(trans.deal, DEAL_SWAP); deal_profit = HistoryDealGetDouble(trans.deal, DEAL_PROFIT); deal_symbol = HistoryDealGetString(trans.deal, DEAL_SYMBOL); deal_comment = HistoryDealGetString(trans.deal, DEAL_COMMENT); deal_external_id = HistoryDealGetString(trans.deal, DEAL_EXTERNAL_ID); } else return; if(deal_reason!=-1) //DebugBreak(); if((deal_type==DEAL_TYPE_BUY || deal_type==DEAL_TYPE_SELL) && deal_magic==InpMagic) { } if(deal_symbol==_Symbol && deal_magic==InpMagic) { } etc } }
