Hi gabiscriba,
When using your own chosen broker the results obtained in a demo account versus a live account should be the same in theory. However, in one case in which I have experience, is that with my Oanda. com account I have found the results from my demo account and my live account were different. It makes me wonder if their demo accounts and their live accounts use the same server with the same historical data which I question. I have asked for clarification but Oanda. com does not answer emails regularly. I have to keep hounding them to get an answer. So far no answer. So it is hard for me to say without any doubt that the results you will get with your brokers demo account will be exactly the same as with their live account. So here is how I decided to proceed with my live Oanda. com live account. I have applied the EAs I wish to trade and have set their lot size to 0.01 lots. I then tested these EAs on my live account. From that testing in my live account I then learned which EAs were the top performers. I then took the top performer and increased its lot size which represented a 1% risk to my account balance. I found this to be the best way to test the EAs. So, it is my opinion if you trade all 8 FTMO robots in your own brokers account by first testing them in the live account you should get favorable results. However, it is also my opinion if you test the EAs in your brokers demo account and then trade them in your brokers live account you may or may not find the top performers from the demo account to be the top performers in the live account it all depends upon whether or not your broker uses the same historical data in both the demo account and the live account. You may try to get an answer concerning this from your broker before proceeding or demo test in the live account. Having said all this it is also my opinion that the majority of traders don’t pay any attention to the fact that the historical data could be different and just go ahead and test in a demo account and them apply the results to live trading. I share my experience to hopefully increase your wisdom concerning trading with various brokers.
Alan,
