Thanks Petko, I appreciate your advice. Maybe I will run the whole experiment again on M15 and H1 aswell!

When you say “choose the best 10 or the best 5 from each”, would you simply do this on win rate, would you be looking to rule out any correlating pairs, or EAs that work off the same indicators, or am i overthinking it? Should it simply be a case of choosing the best 5 or 10 from their win rates?

Thanks Petko, that’s useful.  Its an exciting stage when the first EAs on demo are proving themselves worthy of going to a live account. I have decided that for each EA going into live, I will give it half as many trades as it had over demo to hit my minimum 1.30 profit factor criteria. So If it hit 1.45PF over 110 trades in demo (100 being the minimum), I will give it 55 trades in live to hit minimum 1.30.  That’s enough time to allow the trades to synchronise between demo and live for the same EA, and then some more time to even out some good / bad spells and see, something closer to its true long term performance. I have in mind that any EA that drops below 1.2 profit factor over its total time on live, will get dropped. That way I know it has always contributed profits to my live account, but below 1.2 means it is using valuable margin that could have been given to an EA that performs more profitably.  Ill see how this second rule works out, that’s just an idea at this stage.

I would look at that video as I am curious about the simulated trading, but it is behind a paywall. (I have paid for EA Studio access only). Thanks

Hi Petko, can you advise if it is possible to merge JSON files to create an ongoing historical data set? For example: When I download M1 data from my broker, I can get about 65000 bars, which covers about 2 months of trading. I did this on 26th April and so was running the generator against M1 data covering approximate 24th Feb to 26th April (I forget the exact start date). However this week I wanted to update my data, so I followed the same process to export it from my broker, loaded it into EA Studio, but the new 65000 bar data set was covering 18th March to 18th May, so I “lost” 24th Feb – 18th March. Is there any way to ensure EA Studio keeps and stores previous data uploads with older trading data? Clearly this questions only really relevant for higher timeframe data – M1 and M5 perhaps. Thanks

Ok thanks Petko, I will do that

Thanks Petko, but I am not sure where I set a limit hour? I only wanted to isolate the times at which the trade is opened, which I thought was the purpose of the “entry time” indicator. I don’t want to restrict the time that the trade closes, i simply want it to hit SL or TP. I can’t see a setting where I have instructed EA Studio to close the trades at the last bar and if you see in the final picture – “profit and loss by exit hour” it shows that trades are closing at all hours of the day, not just at 19:00?

Thanks Petko, this makes sense. It looks like the spreads widen significantly at this time? When the NY session closes? I have done some further analysis and I am only getting this problem between 10pm and 11pm GMT, at all other times the same EA is setting up the trade correctly, and the open price is on bar open and 18 pips away from SL and TP.

This is a real shame, as the best 1R:1R strategies i have developed seem to have the majority of their trades open in this hour. Is there anyway around this? Could I adjust the EA SL / TP in some way to account for the wider spread in this hour? I thought a fixed spread broker might be the answer, but I haven’t been able to find one that offers fixed spreads 24 hours a day, do you know of any?

Thanks in advance for your help

Hi, I am new to EA Studio, and am absolutely blown away by this tool. I used to pay a developer 2-300 Euros per EA, wait a week for it to be written and then hope for the best that the back testing might match up to some minimal manual testing. Now I can generate hundreds of EAs in a matter of minutes. I have no idea how long it took to code and build, but I am so glad I found it. Amazing work, I haven’t had any serious results yet, but some early test accounts are showing encouraging gains. Thanks guys

Fantastic, thanks Petko
