Topic: Can someone help out with modification?

Hi,

i wanna to sell a Ea on mql5 market. There is a validation process which is testing the ea from ea studio. I have a problem that this validation didnt pass because there have to be a check before open trades.
-the symbol is inappropriate for trading
-not enough money
-not enough history
-4- and 5-digit symbols
-various tick generation modes

It looks like i have to implement this code function

bool CheckMoneyForTrade(string symb, double lots,int type)
  {
   double free_margin=AccountFreeMarginCheck(symb,type, lots);
   //-- if there is not enough money
   if(free_margin<0)
     {
      string oper=(type==OP_BUY)? "Buy":"Sell";
      Print("Not enough money for ", oper," ",lots, " ", symb, " Error code=",GetLastError());
      return(false);
     }
   //--- checking successful
   return(true);
  }

and this

//+------------------------------------------------------------------+
//| Check the correctness of the order volume                        |
//+------------------------------------------------------------------+
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);
  }

How do i can implement this?

here you can find the article with the functions. but don't know where to put them in ea studio mql file

Re: Can someone help out with modification?

There is a section on MQL5 site for getting a programmer to make stuff.

My 'secret' goal is to push EA Studio until I can net 3000 pips per day....
