EA to place the opposite trade for a fulfilled order

I use the attached script to place buy and sell pending orders (see chart). and i would like to have an ea that replace every closed order( pending order triggered and TP profit reached) by the opposite trade.

say for example that i had a EU pending buy order at 1.30 and take profit at 1.302, if this order is triggered and the TP hit the EA will place a pending sell order at 1.30 and TP at 1.298 .

the other side is when i have a pending sell order at say 1.296 that got triggered and TP hit at 1.294 , the EA will place an order with a buy at 1.296 and TP at 1.298.

the script can place unlimited buy and sell pending order with predefined TP and distance between orders.

please let me know of any question or concern.

thanks.

What happen if pending is trigerred and SL is hit?

the same thing if TP is hit . we should place the opposite trade again . say that a buy is trigered @ 1.3 and it`s SL @ 1.299 was hit, we should place a sell @ 1.299 with same pips for TP and SL .

Forget about your sript... build an EA.

Also, what about previous pending orders? do you delete them?
