@Haliffa-I believe that Coinexx is a company that was established after 2012. Oh, so that means that it might be exactly what you said as data from another broker or liquid provider. I’m not sure how much of an issue it is, but so far I have been profitable. This just leads me to believe that if I was with another broker with actual data, I could have been even more profitable. :)
I only chose this broker because I am based in the US and unfortunately, I have limited choice in brokers. Also, I love that there is a major focus on cryptocurrency.
