Number of points (pips)

Please...

sell order: open price-close price

buy order: close price-open price

for the hole day u need to loop in the orderhistory, filter only closed trades from today, calculate the profit of each order

it's a good day so here you go (not tested) just fastly written here, but you should get a general idea.

i assumed that if one symbol is on subpip mode every symbol it is.

static datetime d1=0;
       datetime tmp=iTime(Symbol(),PERIOD_D1,0);
double profit=0;
if(d1!=tmp){
  for(int i=0;i<OrdersHistoryTotal();i++){
   OrderSelect(i,SELECT_BY_POS,MODE_HISTORY);
   if(OrderCloseTime()!=0 && OrderOpenTime()>=d1  && (OrderType()==OP_BUY || OrderType()==OP_SELL)){
     if(OrderType()==OP_BUY){
       profit+=(OrderClosePrice()-OrderOpenPrice())/MarketInfo(Symbol(),MODE_POINT);
     }
     if(OrderType()==OP_SELL){
       profit+=(OrderOpenPrice()-OrderClosePrice())/MarketInfo(OrderSymbol(),MODE_POINT);
     }
   }
  }
  d1=tmp;
}
if(Digits==5||Digits=3){
  profit=profit/10;
}

Alert(profit);

It worked. Thanks!
