Hey Jaroslav,
Great to hear form you :-)
It definitely sounds like things are improving a lot which is great!
Your first question is around the timings. I personally think the more the better if you have time to update the EAs so if you can make it a quick and easy daily task to do then why not. Its important to tweak your system around your current schedule and make it manageable. BUT how often is necessary is dependent on the timeframe and frequency of how often the EAs trade. For example if your EA’s are H1 and M30 and typically opening trades 1-2x a week then changing a couple of times a week is likely to work well, but if you have M15 and M5 that are trading say 3 or more times a week typically then I would probably favor updating every day or two.
What broker are you using? Demo and live should be very similar so to check this for yourself why don’t you try the following:
1 – Upload the live data and demo data to your EA studio account and then see how the results compare when you switch from using the live to demo data. Also you can check with Mt4 back tester.
2 – If you want to convince yourself of how live and demo compare then why not pick a few single EA’s each for a different pair and trade them each with the smallest lot size on both the demo and live account to compare the results. Of course this could cost you a small amount if they lose but it really shouldn’t be a costly lesson (You could even cheapen the lesson by reducing the stop loss and profit taking from typical max=100 to 50 when generating EA)
Definitely a smart move to run more than one demo at once, just make sure to track everything properly so you learn from all the things you are trying but will hugely speed up the learning.
Keep doing what you are doing. I really think you are going in the right direction, just keep doing what you are doing and learning from the results.
I can understand wanting to get onto live as soon as possible but once you have sufficiently consistent demo results then this will translate to good live results. Whenever you go live, to start you could also put the same EA’s on a demo initially to further build your confidence in this “live ~= demo” equation.
