ok, write a broker plugin is far from my coding capabilities and demo account on IB are allowed only after you have opened a real one. I have tried but IB is not a "customer oriented" broker.
I will stick with the financial hacker version. In order to save time to user, specify the limit broker options for Z8 the manual could be an option. Just a suggestion.
In some other post you mentioned that you are working on other systems based on different assets than forex or CFD. Please take the broker diversification issues into consideration.
Thank You
