Hey Casanogues.
That sounds good, not sure exactly what you mean by not 100% consistent but presumably you mean you are a profitable trader overall?
My advise would be to watch the videos and ask any questions you have. For people who code like myself express gen is super quick and easy to pick up without the videos really (though they are still useful for coders) but I believe that the videos break down everything pretty clearly for non-coders too?
The main benefit I get from express gen is just that it saves me some manual time in my workflow but I would suggest using it as a side to your current workflow until you get the hang of it. Maybe dedicate 80% of your trading time to what you are currently doing in EA studio and 20% to implementing express-gen in the generation process.
Basically express gen is a generator only that works offline and is about 3x as fast as Ea studio, it exports collections that are 100% compatible with Ea studio and can be imported into both Ea studio and fsbpro.
