使用MQL5向专家顾问添加跟踪止损

Question

嗨，我是MQL5的新手，我想在我的专家顾问中添加跟踪止损，但由于某种原因它没有添加。

if(PositionSelect(_Symbol) && UseTrailingStop == true)
{
double TrailingStop = (atr[1] * 3) + close[1];
Trail.TrailingStop(_Symbol,TrailingStop,0,0);
} 

请注意，close[1]表示前一个柱状线的收盘价，atr[1]表示平均真实范围的值。我做错了什么?????

Answer 1

好了，希望对大家有帮助。

//--- trailing position  
for(i=0;i<PositionsTotal();i++)
{
if(Symbol()==PositionGetSymbol(i))
{
if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_BUY)
{
sl=MathMax(PositionGetDouble(POSITION_PRICE_OPEN)+Spread*_Point,Bid-SL*_Point);
if(sl>PositionGetDouble(POSITION_SL) && (Bid-StopLevel*_Point-Spread*_Point)>PositionGetDouble(POSITION_PRICE_OPEN))
{
request.action = TRADE_ACTION_SLTP;
request.symbol = _Symbol;
request.sl = NormalizeDouble(sl,_Digits);
request.tp = PositionGetDouble(POSITION_TP);
OrderSend(request,result);
if(result.retcode==10009 || result.retcode==10008) // request executed
Print("Moving Stop Loss of Buy position #",request.order);
else
{
Print(ResultRetcodeDescription(result.retcode));
return;
}
return;
}
}
if(PositionGetInteger(POSITION_TYPE)==POSITION_TYPE_SELL)
{
sl=MathMin(PositionGetDouble(POSITION_PRICE_OPEN)-Spread*_Point,Ask+SL*_Point);
if(sl<PositionGetDouble(POSITION_SL) && (PositionGetDouble(POSITION_PRICE_OPEN)-StopLevel*_Point-Spread*_Point)>Ask)
{
request.action = TRADE_ACTION_SLTP;
request.symbol = _Symbol;
request.sl = NormalizeDouble(sl,_Digits);
request.tp = PositionGetDouble(POSITION_TP);
OrderSend(request,result);
if(result.retcode==10009 || result.retcode==10008) // request executed
Print("Moving Stop Loss of Sell position #",request.order);
else
{
Print(ResultRetcodeDescription(result.retcode));
return;
}
return;
}
}
}
}
