More specifics would help.

By the title, it also sounds more like a trade management EA. Steve Hopwood wrote an excellent Multi Purpose Trade Management EA (MPTM). Read its documentation, it'd probably do what you want.

That said:

extern bool EquityStopLoss = TRUE;
extern double EquityPercent = 10.0; //for 10% drawdown

int start(){
   if(EquityStopLoss&&1-AccountEquity()/AccountBalance()>EquityPercent/100){ //if drawdown exceeds 10%
   CloseAll(); //Close all trades
   }
}

void CloseAll(){ //Close all BUY and SELL orders including Pending Orders if any
   bool result=false;
   for(int i=OrdersTotal()-1;i>=0;i--){
      OrderSelect(i,SELECT_BY_POS,MODE_TRADES);
      if(OrderSymbol()==Symbol()&&OrderMagicNumber()==Magic)result=OrderClose(OrderTicket(),OrderLots(),OrderClosePrice(),MaxSlippage*mt,Blue);
      if(result==false){
         Print('CloseAll failed with error#',GetLastError());
         continue;
      }
   }
}

I never mentioned Metaquotes.

Google this 'Multi Purpose Trade Management EA'. Read the 1st entry, it should be from forexfactory.com

... sometimes I can sympathise with Steve.

You could copy that text, open the Meta Editor, and paste that into an EA. (There are two more variables that need to be defined though.)

But you should skip that and just use the Multi Purpose Trade Management EA by Steve Hopwood in the forexfactory.com link.

I have a programmer that could do that money management program change for a fee. Hes very good. Most likely would charge form $35 to $75 would be my guess if the prg isnt private or locked.

Dude i would program those lines for ar 5 $
