Modification of existing scripts mt4

HI guys, all i need is to change TP & SL from setting by points/pips instead of price

individually from every begin of  limit/stop order

currently 

if set limit order BUY1 BUY2 BUY3 BUY4

current setting is only able to tp at the same PRICE

-all i want to do is i can set by pips/or point from the beginning of every limit trade 

example 

TP point - 50

BUY1-1400(tp 1450) BUY2 -1450(tp 1500) BUY3 -1500(tp 1550)

same goes to SL
