example :
broker allow min of 10 pips TP..i want to set my TP only for 5 pips..is it possible?

Yes it's possible, code your EA to keep track of either pips OR money internally. Don't use any TP or SL in your order send functions. Of course you might get re-quoted a lot, or have large slippage. At least the broker won't know exactly what your up to though.

i have zero knowledge about programing..can anybody do it for me??

This is what you need;
