Martingale Lot Increase On Next Signal

Abubakar Abu Saidu 2020.05.13 13:34

Hello.. i cant figure out whats wrong with my code..

the lot decreases on next signal instead to increase

input string MartinGale = "===< MartinGale Settings >===";
input double          Risk=1.0;   
input double          Multi=0.5;

double          MinLot,MaxLot,Contract,lot;
int             DealNumber;
long            Leverage;

int OnInit()
  {
      Leverage=AccountInfo.Leverage();
      MinLot=SymbolInfo.LotsMin();
      MaxLot=SymbolInfo.LotsMax();
      Contract=SymbolInfo.ContractSize();
      DealNumber=0;
   return(0);
  }
void OnTick()
  {
if(buysignal())
{
DealNumber++;
Lot=AccountInfoDouble(ACCOUNT_FREEMARGIN)*Risk/100*Leverage/ContractSize;
if(DealNumber>1)Lot=Lot*Multi*(DealNumber-1);Lot=NormalizeDouble(Lot,2);
if(Lot<MinLot)Lot=MinLot;if(Lot>MaxLot)Lot=MaxLot;
 
      MqlTick last_tick;
      double price = last_tick.ask;   

ticket = sendbuy(ORDER_TYPE_BUY, price,stoplossB(),Btp1(), Lot, "");
DealNumber--;

}
  }
   


   }

if i change this it will increase lot on every new signal.. but will continue to increase if Total Orders is = 0

DealNumber++;

with this.. it will restart if Total orders is =0

DealNumber--;

Ill really appreciate mod to my code

Hello,

try something this....

Hi.. Thanks for your response

i tried it and it was not increasing the lot size on new signal..

instead it decrease

Abubakar Abu Saidu 2020.05.14 00:38 #3

Tried this also lot not increasing on new signals

input string MartinGale = "===< MartinGale Settings >===";
input double          Risk=1.0;
input double          Multi=0.5;
double          MinLot,MaxLot,Contract,lot;
int             DealNumber;
long            Leverage;
input double          LotIncrease      =0.9; 
input double         StartLot=0.5;

Oooohh..

since youre counting buy orders, who not just calculate the lostize of the next buy order in that function?

each time through the loop your global buy_lotsize variable gets increased accordingly.

Although martingale is a fools errand..... Ive seen a proof that shows that probability of doubling your account is always exactly equal to the probability of a single winning outcome, and the probability of zeroing your account is equal to the probability of a single losing outcome....

i want to try something with martingale..

can you modify the wrong part of my code!!

You code not working.

Please fix your code first.

Martingale, guaranteed to blow your account eventually. If it's not profitable without, it is definitely not profitable with.

Hi.. yes i know i just want to try something with it!!!

//--// some pseudocode used in this example: do not copypasta: fix it.
double lotsize(void){
        if (OrdersTotal() == 0) return(StartLot); //does this even need a comment??
        // OrdersTotal must be >0 to get to this line
        double ret=StartLot; // ret is just short for "return value"
        for(int i=OrdersTotal();i!=0;i--){ // you may as well count down as up, often its easier and comparing to zero usually takes less clock cycles
                if(get the right order type) ret *= LotIncrease; //since you have a nice exponential lotsize formula, just use it
        }
// ret should now be the next lotsize in the sequence.
 return(ret); //ummm??
