         Trade_reqst.action=TRADE_ACTION_DEAL;       // Тип: немедленное совершение сделки
         Trade_reqst.symbol=_Symbol;                 // Инструмент: текущий
         Trade_reqst.volume=Lot;                     // Объём: 1 лот
         //Trade_reqst.price=SymbolInfoDouble(_Symbol,SYMBOL_ASK)-TakeProfit*_Point; // Цена исполнения
         Trade_reqst.type=ORDER_TYPE_BUY;            // Тип ордера: на продажу
         Trade_reqst.type_filling=ORDER_FILLING_RETURN; // Политика исполнения 
         Trade_reqst.sl=last_tick.last - StopLoss * _Point;  // Stop Loss
         Trade_reqst.tp=last_tick.last + TakeProfit * _Point; // Take Profit
      // Trade_reqst.tp=Trade_reqst.price + TakeProfit * 2 * _Point; // Take Profit
      //--- 2. Отправить торговый приказ
         MqlTradeResult Trade_reslt={0};             // Инициализация структуры результата торгового запроса
         OrderSend(Trade_reqst,Trade_reslt);         // Отправка торгового запроса на сервер
   //--- выведем в лог ответ сервера  
   Print(__FUNCTION__," - : - ",Trade_reslt.comment);

So what to do about this problem? How do you get around it properly?

I cannot test the EA correctly. A lot of trades are erroneous.

Also, gentlemen, why is the scale on the chart not based on whole numbers (round numbers) or even multiples. My brain boils when I visually try to calculate some kind of pattern or put stops.

How do you calculate cell differences, keep a calculator nearby?
