Opposite Hedge Position

Hi All

Im looking for some help, I've done some C# coding before but am still learing cAlgo API calls etc. When I am after is C# code that takes an opposing position once the pNl is greater then X.

So Im in position AUDUSD, the PNL is -2000 (2000 is my X value set) and I have a current position of 80000 volume in a buy. Take a 80000 position in a sell out once the PNL is greater then 2000.

Any additional snippets for managing the position ie once it or overall position hits breakeven sell then that would be great cheers.
