EA LOGIC MODIFICATION AND UPGRADE

I noticed my EA is profitable but it picks a lot of wrong signals which gives accounts high DD. EA use RSI, STOCH, MA & ATR. I want the logic of EA check to see why it enters the market on wrong signals and modified. Then also the developer must add ADX, MACD and BOLLINGER BAND indicators to the EA. The indicators must have options in input parameters where they can be changed or option to use or turn off. Developer must test EA, optimize and give results.
