Choose the value of the lot level martingale instead to multiply
double MartingaleLevel(double lastlot) //pass lastlot parameter from your calculatelots() function { if(lastlot < martingaleL1) return(martingaleL1); if(lastlot < martingaleL2) return(martingaleL2); if(lastlot < martingaleL3) return(martingaleL3); if(lastlot < martingaleL4) return(martingaleL4); //etc if(lastlot < martingaleL20) return(martingaleL20); return(0); //oops !! if we got here we probably just blew the account; }
looking at what you posted as I thought it would function more as my limited knowledge about mq4 could do not work.
I think it gave little information could you make it clearer

The code I gave you in my reply, is an example of a function to return the next one in a sequence of lot sizes held in global variables; martingaleL1 through martingaleL20. When you need to get the next lot size in that sequence pass to it, in a function call, the previous lot size. If you do not know how to do that read, functions

Someone?
" I think it'll be about 5 days trying to make it work pity me :) "
Would that be a reason to do it not at all ??
If you want someonelse to do it for you then placing a job at Jobs will help you more
If you open a job there for doing this i can help you also if you choose me when i also react as one of the developers
But SDC has given you already a big help here how to solve this problem
If you try to learn yourself to code mq4 and you need some help then you can ask here and with the hints we give
it will for you the help you can get here in how to code and learn to write own programs for MT4
This forum is not the place to ask for coding your programs for free
It is a forum for helping those programmers who wants to learn seriously creating own programs
The Book and some programs in Code Base might help you.
Although I have to warn you about Code Base not all programs there are written well
This Forum is to help you with solving a problem in how to code
I'm sure you can do this if you take the time to learn how to read and program mq4 language

Usage that code martingale which for multiplying a lot starting with a loss so forth till the MaxLotsAllowed
I wanted to specifically choose the lot for each level martingale.
Example:
Someone can help me, thanks
