Please help optimize this Ea.

 

Ok I have this Ea for trading binary option with this broker Market World and work with a timeframe of 5M in mt4 chart using martingale system. So far is working ok, but What I'm looking for with the help of the community is to boost the accuracy and optimized of this Ea and also more signal.

Here is the pdf with instructions and the metatrade file, and some trades that I make.

Thanks and appreciate your help.
