Hidden Trailing Stop Manager

I am looking for an ea or script or indicator that will manage the open order. I have an ea that opens hedge position, and im looking for an ea/indicator that will place hidden trailing stop as soon as one of the hedge position hits stop loss.

Rules of the Hidden Trailing Stop Manager.

1. will only be triggered if the stop loss of one of the hedge position gets hit

   example open position buy eurusd 1.5050 sl 1.5000

                                      sell eurusd 1.5040 sl 1.5090

   if the price moved to 1.5000, buy eurusd  sl gets hit, the Hidden Trailing stop loss manager will start strailing the sell eurusd order.

2. Hidden Trailing stop manager will not be used if there are two hedge position still open (buy and sell). original sl will be used for the two orders.

3. pair filter. I should be able to select on which pair to use.

4. Hidden Trailing stop should be hidden so that broker will not be able to see my trailing stop.

let me know

thanks
