I would like to test MC.net for TWS but it seems this posibility is not allowed with IB demo account.
Could you confirm ?

I agree,that is an important feature which lack to MC.NET.
Duplicate code is a non sens in programmation and a cpu time consumer.

And is it possible to add this possibility in a next release ?
Same thing for other non regular charts ?
MC offer varities of chart types but don't allow porfolio backtest !!!?
