Hi.. How to make this layer per group remove 1 layer for each group or make it dynamic when layering using martingale..

     }

   return(label);
  }

My code line

if(MathMod(TotalOrder(orderType)+1,Layer_Per_Group)==1) multiplier = LotExponent;

normally if i set 10 layer per each group it open

0.01x10 0.02x10 0.04x10

and so on using martingale layer per group set..

But how to make it -1 each layer per group like this

0.01x10 0.02x9 0.04x8

And so on until left with 1 layer then martingale normally for each layer after that??

i want to make it -1 each layer per group or make it open layer more versatile or dynamic.. Maybe from first group open 10, then next group open 10 also, then 8 then 5 something like this..
