Build me a classic martingale EA with some modify setting

I would like to build a classic martingale ea but with my own setting whereby, i can select to either start with buy or sell options, initial lot size, lot increment, sl and tp level, pip steps( but it will open new positions when the position is in profit instead of the other way, eg it will open buy and when the buy in profit and with the pip steps, it will open another buy and buy until it hits the tp level.) For the SL , i want it to only set for the initial position which is the first position.The following position will also follow the first position SL
