Grid EA - Need Help to Make It More Beneficial

Hi,
I have found Grid EA Rubberband in http://codebase.mql4.com/5900
this is good EA but i would like to add Safety point as.....
Add in pipstep after certain level EA should start Buy/Sell lots in same direction.

can any one help me to make this EA better

Reverse order (anti) will works better than this

I just backtested this EA, as is. For USDCHF & USDJPY.
Look graph.
These results correspond to your ones?

P.s. Near half of the testing period EA stopped to open close orders, and zigzag in the end corresponds to
forceable close-up of the orders , as testing period finished.
