How to close all of your open positions at the same trailing stop price?

[kevin11]

I want to open say 4 or 5 buy/sell trades at different price for the same pair and then use trailing stop to close them. Currently, my EA close the trades at different trailing price, but, I need all the open trades to be closed at the same trailing stop price of my first opened trade. For example, if my 1st trade is having a trailing stop at 1.39564, I need all of other open trades to have the same stop loss price.

Loop DOWN through all the orders and modify them

    for(pos = OrdersTotal()-1; pos >= 0 ; pos--) if (
        OrderSelect(pos, SELECT_BY_POS)                 // Only my orders w/
    &&  OrderMagicNumber()  == magic.number             // my magic number
    &&  OrderSymbol()       == Symbol() ){              // and my pair.
