Hello,

I don't know if this job is possible,i want an ea or script that can pending stop order opposites to what i enter.

For example:

1)I manually enter sell with 0.10 lot of EURUSD at 1.31200

2)then the ea will open buy stop at 1.31300 or can be adjust example 10 pips above the 1.31200 or 20 pips or 30 pips.

3)I can adjust the stop order size whether it can be x2 or x3 or x4 the manual order on 1)

after the above been done,if the buy stop had triggered and running.I want the ea to open sell stop at the 1) position of 1.31200 and i can adjust the stop order size whether it can be x2 or x3 or x4 the buy stop order.

and its vice versa

if i entry buy the ea will open sell stop
