Opening/Closing orders based on pip size

Hello,

I need an existing SMA crossover script modified to open and close orders based on pip size above or below SMA using current trading candle. Currently the EA trades when the candle closes above or below SMA I need someone to replace this functionality with pip size above or below. No TP, SL, TrailingStop.

E.g. We have an open buy trade, making about 100 pips then the markets turns, and the candle starts to go below SMA, after going 30 pips below SMA the trade stops, the candle doesn't even have to close.

Let me assure you that the existing script is very simple since I'm learning MQL4 and is only about 150 lines, the bit that needs interpreting is less than 50 lines. 

I know the EA needs more work, but I'm learning and just need this part of the puzzle.
