Hey Ilan,
I am glad to hear from you.
I think you are doing a very good job.
For sure you need to use one and the same broker for Live and for Demo trading. In most of the courses, I use JFD for Forex, and Pepperstone for Crypto.
There are some tips at the end of the page with the trusted brokers, that will help you compare the Demo and the Live accounts:

Also, what do you mean that you have more money in the Demo account? per day or in total. I guess you started the Demo account earlier, which leads to more money in there.
Yes, looking at the last 3-5 days is a great idea to have an idea of which EAs are currently profiting.
Kind regards,
Petko A
