Hey Gowiso,
You are welcome, here we are happy to share the experience because this way better results come for everyone.
If you want to start with 500 USD I would suggest you to go for 0.01 lot and max with 10 EAs.
Now, once the EAs are on live, you should monitor their performance and have a different filter there. For example, I keep looking at the last 10 trade for Profit Factor 1.2, and just recently I added the R – squared above 60. So if it falls below that, I remove the EA from the live back to Demo for further tests.
So in the live account, you should keep only the EAs that profit.
