Stop Loss Management EA coding

I want to modify my  Bollinger Band(BB) EA. it is just a simple logic. If my EA opens a trade, and the price goes against me or the price goes in the opposite direction until it reaches a set pips distance and at any stop loss distance, the modified (BB) EA should start a loss management logic or protocol provided by (you the programmer) to the extent the loss management logic  or protocol will exist or close the trade at 0.00, a small pip like 1 - 5 pips loss. That means if  there is a losing trade, and the loss increases to a particular distance that i set, the EA strategy or logic you the programmer will provide will start managing the loss until it exit at 0.00 or a small pip like 1 - 5 pips loss.  Thats all.
