I mainly use Multicharts to test and trade, I used NinjaTrader in the past to automate trading but as I'm not a programmer it was too difficult for me to program new strategies there so I changed to Multicharts whose programming language is easier for me to manage.
I think anybody can do that if I did but obviously you need some time to digest the concepts properly!
Easylanguage programming scripts are somehow similar to prorealtime stuff so if you program there you should get pretty easily to Multicharts.
In the videos I do show the process of developing strategies so that students become independent in their path, doing so I deliver some strategies which have been working in the past and show to be working today as well, nobody can tell if they will be working for the next years obviously but so far they are doing well.
Remember anyway that the purpose is to teach you how to develop on your own!
