EA that will inverted position according to a quote

At 100,150 there´s 1 lot size short, i will set it by myself. I will inform EA that I have a short position at 100,150 and i´d like the ea to set buy stop at 100.170 with 2 lotsizes(so it will stop my short position and start 1 lotsize long). let´s say price goes up until 100,300, i would be long at 100,170 with 1 lot.

Eventually price will come down from 100,300 and I´m long 1 lot at 100,170. EA will set sell stop 2 lot at 100,150(as soon it goes long from 100,170).

My broker doesnt have hedge option. So there will be no stop loss and take profit. Stop loss will inverted position from this line, and the TP i will set myselef at chart.

I want to have a panel that shows all set prices and which ones are enable/disable. 

I can provide a demo account of my broker for you to test.
