Any plans to have that as an optional alternate version since I feel like I can leave that setting on if it's only for this indicator?
I can't go the EA route because my funded trading program rules (and even others) do not allow to open orders with EAs.
I wouldn't add DLL calls to PSC. You can hire some coder to implement the button for you (PSC is open-source so anyone can modify it). However, are you sure your program allows you to open trades via a script? As far as I know the mechanics of their (EA's and script's) work is the same and if broker turns off trading via EAs, scripts are also affected.
