I cant pass mql5 validation

[Abdelrahman Ahmed Mahmoud Ahmed]

I can't pass the MQL5 validation test for my EA.
It keeps giving me this error.
test on EURUSD,H1 (netting)
2020.05.26 12:02:03 failed instant sell 5 EURUSD at 1.09610 sl: 1.19611 tp: 0.99611 [Volume limit reached]
Even though I checked the max and minimum volume for trade and also checked lotstep, here is my order execution function:

void executeBuy(double lots)
{
double Ask=SymbolInfoDouble(Symbol(),SYMBOL_ASK);
double Bid=SymbolInfoDouble(Symbol(),SYMBOL_BID);
double takeprofit= Ask+tp*_Point;
takeprofit = NormalizeDouble (takeprofit,_Digits);

double stoploss = Ask-sl*_Point;
stoploss = NormalizeDouble (stoploss,_Digits);

double orderlot = lots;
orderlot = (int) (orderlot/SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_STEP))* SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_STEP);
orderlot = MathMin (orderlot, SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_MAX));
orderlot = MathMax (orderlot, SymbolInfoDouble(_Symbol, SYMBOL_VOLUME_MIN));

double margin;
if (OrderCalcMargin (ORDER_TYPE_BUY, Symbol(), orderlot, Ask, margin) && margin > AccountInfoDouble (ACCOUNT_MARGIN_FREE)) 
{
return;
}
int buyticket = trade.Buy(orderlot,Symbol(),0,stoploss,takeprofit,NULL);

Print("unable to place buy order. Error: ", trade.ResultRetcodeDescription(),", Code: ", trade.ResultRetcode());
}

What value am I supposed to put in the string &description here?

bool CheckVolumeValue(double volume,string &description)
  {
//--- minimal allowed volume for trade operations
   double min_volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_MIN);
   if(volume<min_volume)
     {
      description=StringFormat("Volume is less than the minimal allowed SYMBOL_VOLUME_MIN=%.2f",min_volume);
      return(false);
     }

//--- maximal allowed volume of trade operations
   double max_volume=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_MAX);
   if(volume>max_volume)
     {
      description=StringFormat("Volume is greater than the maximal allowed SYMBOL_VOLUME_MAX=%.2f",max_volume);
      return(false);
     }

//--- get minimal step of volume changing
   double volume_step=SymbolInfoDouble(Symbol(),SYMBOL_VOLUME_STEP);

   int ratio=(int)MathRound(volume/volume_step);
   if(MathAbs(ratio*volume_step-volume)>0.0000001)
     {
      description=StringFormat("Volume is not a multiple of the minimal step SYMBOL_VOLUME_STEP=%.2f, the closest correct volume is %.2f",
                               volume_step,ratio*volume_step);
      return(false);
     }
   description="Correct volume value";
   return(true);
  }

That parameter is an output parameter, not an input parameter. A value is returned.

EDIT: Remember to also check the SYMBOL_VOLUME_LIMIT property.

OK,thank you!

After I implemented the checks and tried to validate the EA, I keep getting this error

If you have studied SymbolInfo.mqh correctly, then your problem "test on EURUSD,H1 (netting) not synchronized with trade server" will be resolved. ^_^
