Hi,

You could use this formula in OrderSend() function to spend the lot size for each new pending order:

lots*MathPow(lotmultiplier,n)

ok thanks really helpfull and if i wanna wait  x time before open every pending ?

So you could use this below before the "for" loop:

   static datetime lastTime=TimeCurrent();
   if(TimeCurrent()<lastTime+X_Minutes*60)return;//X_Minutes is a global extern variable that can be any integer positive value
   lastTime=TimeCurrent();
