Create hedge EA , with one time trailing stop loss

Concept

Suppose I have 3 open traded on one symbol i.e GBPUSD with total 3 qty SELL i.e

1. SELL at 1.41000

2. SELL at 1.41100

3. SELL at 1.41200

Now I wont open new SELL and I will wait for my TP which will be average minus 100-200 points. 

We note down the lowest value i.e 1.41000

Now, Market is up 1000 point from lowest point i.e 1.41000 so Hedge will start by placing 3x2= 6 quantity of BUY position at 1.42000 ( Traded at market price when limit is reached ) with a SL of 50 points from order price i.e 1.41950

Suppose market went up 50-100 points from order price i.e  without touching SL so EA should modify SL to cost i.e from 1.41950 modify to 1.42000 so that if SL trig we do not book loss.

When any SL is triggered then next hedge should start with 50 point above the SL value at which hedge is closed. It means suppose SL of 1.41950 is triggered then next hedge will again start at 1.42000 and so on. Another example if SL is triggered at  1.42000 then next hedge will start at 1.42050

Note : In any of the case when floating p/l reach "Target Profit to close all" value i.e above 100 USD then close all open positions available either Buy/ Sell.

Feel free to discuss further. Thank you
