I use it mostly because I leave it generating 24×7 all day long in the background on my server without worrying about a web browser crashing or using too much RAM, etc., saving every 15 minutes, so I can stop it at any time, but it just runs indefinitely. And I validate once or twice a week (usually on weekends) on data from multiple brokers, to only pick strategies that pass Monte Carlo on all of them for several different date ranges (last three years combined, 3yrs ago alone, 2yrs ago, 1yr ago, etc.). If it makes it through the “funnel” of about 12 validation steps, then I import them into EA Studio and make a portfolio EA. For me, that whole validation process across three brokers is so much faster to script with a single file that I double click than to do it for each symbol and each broker in EA Studio. But I still use EA Studio in the end to combine the passed strategies into portfolios that I swap out on weekends. All of that could most certainly be done without the Express Generator, but for me it automates it with less mouse clicks. It’s not so much because it generates more strategies faster persay (although it does), it’s more that it makes my time more efficient processing them afterward.
