Need expert can auto close order when new opposite order placed

Hi everyone, as i mention in title. I need an ea can auto close orders of a symbol when new opposite order of that symbol placed. Example: i have 3 orders are running: BUY GBPUSD, SELL XAUUSD, SELL BTCUSD. If SELL GBPUSD is placed after that, BUY GBPUSD is immediately closed but SELL XAUUSD, SELL BTCUSD are still running with BUY GBPUSD. When new opposite orders of XAUUSD or BTCUSD received, ea will do similar.

Thank you very much !
