I use ExpressGenerator to create strategies for use with EA Studio. I find creating my strategies in ExpressGenerator to be about five times faster than creating strategies in EA Studio. So by running the ExpressGenerator for 24 hours, or one day, I create about the same number of strategies that would take a week to create using EA Studio. In the ExpressGenerator I filter the generated strategies using the Acceptance Criteria built into ExpressGenerator. I do not use Monte Carlo in ExpressGenerator although it is available. Once ExpressGenerator creates the strategies it saves them in a collection. It is then necessary to import the collection into EA Studio. In EA Studio I may decide to use Monte Carlo and to do any final filtering based upon how I am going to use the strategies. I then select the strategies I decide to trade and download them as Expert Advisors. Keep in mind ExpressGenerator works with EA Studio and is not a stand alone product. Its value is in speeding up the process of creating strategies. EA Studio is then used to convert the strategies into Expert Advisors.
