Trade Copier (MT5 to MT5) with my specification

hi need a copier mt5 to mt5 with following feature

 if a trade opened in master account the copier can put OCO pending orders in target account above and below (10 pips..defined by the user) of the actual source order price. copier must put two order 10 pips above and 10 pips below and if one of the order gets executed it must cancel the other one. once pending order execute trades will be closed once trade will be closed in master account or if the trade is closed in master account and both orders are not executed then copier will remove both pending orders from slave.

its an additional function not available in other copiers so if you have developed copier already for marketplace you need to add this function
