Grid trading, help with code

New comment
 

HI, I am a senior high school student and I am new to trading and mt4 and ive been studying different financial market for the last 6 months. this grid system has a 60-70 percent winr ate and have a high gains in a day. this system doesn't use any indicator and news or fundamentals because indicator can be manipulated and news can give traders a false signal or etc. 

this is a grid system. the strategy works by placing a order ex(Buy trade) and if the order hits take profit. it will open another buy order else if the order hits stop loss. it will open the opposite order ex(Sell Trade) and double the lot size.

problem:

code and broker

code:

the code of this EA is garbage because I am not efficient on the way i code hehe

the problem is the martingale. I don't know how to code martingale that will automatically double the lot size if the order hits the stop loss 

suggestion:

i need a martingale code for this EA to work and I want to learn on how
