Thread: Add a martingale

Note that this martingale is not conventionnal. The lots size is increased when there is a loss, and decreased when the is a profit. While it should start again at initial lots when the last serie of consecutive loss finishes on a win.

If you have a function for a basic martingale, don't hesitate to post :

After extern parameters, add :

Code:

extern double Lots=0.01;//|----------------------lots
extern bool Martingale=false;//|-----------------martingale
extern double Multiplier=2.0;//|-----------------multiplier martingale
extern double MinProfit=50;//--------------------minimum profit to apply the martingale

After start(){, add :

Code:

   if(Martingale)CalculateMartingale();Balance=AccountBalance();

At the end of the code, add :

Code:

void CalculateMartingale()
{
   double InitalLots=0.01;
   double MinLots=MarketInfo(Symbol(),MODE_MINLOT);
   double MaxLots=MarketInfo(Symbol(),MODE_MAXLOT);
   if(Balance!=0.0)
   {
      if(Balance>AccountBalance())Lots=Multiplier*Lots;
      else if((Balance+MinProfit)<AccountBalance())Lots=InitalLots;
      else if((Balance+MinProfit)>=AccountBalance())Lots=Lots;
      if(Lots<MinLots)Lots=MinLots;
      if(Lots>MaxLots)Lots=MaxLots;
   }
   return(0);
}

Updated.

I have added the InitalLots.

I downloaded Ilan 1.42 today and will be looking at ALL the Loss Control parameters.....I was doing a good job controlling risk with PipStep...and Take Profit...but 800 Pip drop was too much... I'm now a BIG believer in avoiding account blow out. Do you have the code described here in the "Martingale" thread already working in an EA? Have you ever considered adding code that would automatically close losing positions as the T/P goes beyond the entry value when additional orders with larger Lot Exponent are created? It might be a nice addition to Ilan 1.43..
Should this post be in the Ilan thread?? Thanks Bill

Hi BillR and welcome,

No I have not yet enabled this martingale in a code. But I have already tried it and it works fine.

I don't understand your other question.

What does it mean by the last series? doesn't it always decrease on a win? I am confused...

Say I start with 0.01...then lose....so the next is 0.02....then I win...then it goes back to 0.01....right?

uhhh err...wait....lets say I start with 0.01 and I lose...then 0.02....then I lose again....0.04....then I lose again....0.08....then I win...so it goes to 0.04...THEN IT WINS AGAIN AND STARTS OVER TO 0.01...or does it go down to 0.02 first?

The lots size is increased when there is a loss, and decreased when the is a profit.

While it should start again at initial lots when the last serie of consecutive loss finishes on a win.

a T/P is also set.... higher. When the value of the currency changes it either closes the order at a profit (the T/P) or goes down the Pip Step value and a second order is entered with a new T/P (and bigger lot size). The T/P of the first order is also changed to the new T/P value of the second order. As a third order is entered all the orders are modified to change their T/P values to the T/P value of the third order. But now depending on your EA T/P and/or Pipstep "Input" values when the value of the currency finally goes up to the T/P point the first order will be closed at a small loss while the 2nd and 3rd orders, which have larger lot sizes, will close at a profit. (If you have many open orders you could also have multiple losing orders). Could order "One" be closed at a small loss when order three is created? As the loss from Order one only gets larger as additional orders are created. This way we can avoid the growing additional loses as additional orders are created. Kind of like a Stop loss triggered by the T/P value. Once an order goes on the losing side of the T/P.... close it automatically instead of letting it turn into a bigger loss.
Thanks again Bill

Hi BillR,

Ok I see, interesting.

I don't know how to code that. I could use a hidden TP, but it would be quite complicated to develop. Maybe another programmer will help.

Correct, it is not the last, but the previous. If you win at the end of a serie, then you start again at 0.01, etc...
