Read research about traders and how majority lose money.
Arbitrage is tricky too and can bite you.
This is a huge bet for OP but if it's effective on him, I'm happy to see that he's making his life and fortune through it. What's bad is that, I'm not like him that's very good on it. I've done that before but to no avail and no luck found. It take guts to quit your full time job and replace it with trading. I've known people that did that and reading something as what OP intended to share is absolutely fascinating because as you've said, majority are losing from it but on him, it's the opposite.
