Thread: Add a martingale

Hello FUNYOO i have these WRONGS:
57:1;'history' - expression on global scope not allowed
58:7;'history' - expression on global scope not allowed
58:17;'{' - expression on global scope not allowed
67:4;'mlots' - expression on global scope not allowed
68:7;'martingale' - expression on global scope not allowed
68:21;'lastprofit' - expression on global scope not allowed
68:34;'mlots' - expression on global scope not allowed
68:56;'lastlot' - expression on global scope not allowed
68:64;'multiplier' - expression on global scope not allowed
68:75;'lotdigits' - expression on global scope not allowed
68:91;'mlots' - expression on global scope not allowed
68:97;'lots' - expression on global scope not allowed
68:63;'*' - both operands are to be numeric
Please help me, thank you.

At the beginning of the code, in the extern parameters add :

Code:

extern bool martingale=false;          // enable the martingale
extern double multiplier=2.0;          // multiplier used for the martingale
extern double lotdigits=2;             // 1 for minilot, 2 for microlot

After the extern parameters add :

Code:

double mlots,ilots,lastprofit,lastlot;

int i,history;

In the start body add :

Code:

   history=OrdersHistoryTotal();
   if(history>0){
      for(i=0;i<history;i++){
         OrderSelect(i,SELECT_BY_POS,MODE_HISTORY);
         if(OrderSymbol()==Symbol() && OrderMagicNumber()==magic){
            lastprofit=OrderProfit();
            lastlot=OrderLots();
         }
      }
   }
   mlots=0;
   if(martingale && lastprofit<0)mlots=NormalizeDouble(lastlot*multiplier,lotdigits);else mlots=lots;

In the mm function (if you have one), add :

Code:

 && (martingale==false || (martingale && lastprofit>=0))

Before each ordersend function, add :

Code:

if(martingale)ilots=mlots;else ilots=lots;

Finally, replace lots in the ordersend function by ilots.

Any improvement on the Martingale code ?

As when connection error and re-login many times, the Martingale Lot size will quantum leap to future as present lot size has loss in the bad connection.

It seem like the history lot calculation re-stack and re-stack when re-login ?

Nothing Attached...
