EA for trailing stop loss for multiple open positions on currencies

I am developping a new EA that enables to take multiple orders with set Stop Loss and Take Profit . A new feature must be added to this EA . The trailing stop loss should be adapted after the opening of the positons , and refer to the lower lows and higher highs . The script is just for finding the current higher high and lower low of the day , and then trigger the order adjustement with modify functions and the rest of the EA . You can contact me to talk about the EA and see in how many days the Ea could be developped . A adapted script that works well , all day and sometimes weekly .
