I believe I am doing the exact same as in the MQl5 guide, 820 and 1517. Could someone tell me what I am doing wrong? //--- Preparing the request double BuyAsync(double volume) {MqlTradeRequest request={}; request.price = SymbolInfoDouble(_Symbol(),SYMBOL_ASK); // Long request.magic = EXPERT_MAGIC; // EA magic number so you can track trades request.action = TRADE_ACTION_DEAL; // Market order request.symbol = "EURUSD"; // Symbol request.type = ORDER_TYPE_BUY; // Long request.order = "OrderTicketBuy"; // The orderticket so you can trace the individual trade request.deviation = 5; // Maximum price deviation request.volume = 0.25; // This should be €25.000 request.tp = tpLong; // Take profit long request.sl = slLong; // Stoploss long request.comment = "Buy using OrderSendAsync()"; MqlTradeResult result={}; if(!OrderSendAsync(request,result)) { Print(__FUNCTION__,": error ", GetLastError(),", retcode = ", result.retcode); } }

If it helps anyone, this is the answer to the original question: //--- Preparing the request void BuyAsync() {MqlTradeRequest request={}; request.price = SymbolInfoDouble(_Symbol,SYMBOL_ASK); // Long request.magic = EXPERT_MAGIC; // EA magic number so you can track trades request.action = TRADE_ACTION_DEAL; // Market order request.symbol = _Symbol; // Symbol request.type = ORDER_TYPE_BUY; // Long request.order = "OrderTicketBuy"; // The orderticket so you can trace the individual trade request.deviation = 5; // Maximum price deviation request.volume = 0.25; // This should be €25.000 request.tp = tpLong; // Take profit long request.sl = slLong; // Stoploss long request.comment = "Buy using OrderSendAsync()"; MqlTradeResult result={}; if(!OrderSendAsync(request,result)) { Print(__FUNCTION__,": error ", GetLastError(),", retcode = ", result.retcode); } The difference is in the first couple of lines.
