Actually, after watching Coral for many years, I am convinced I know what he's doing. It's some variant of the simple naked price action method using trend line, levels of support and resistance, and possible a basic break out system. I suspect common sage of Fibonacci retracements also fit into the game he's playing.
It's the most common trading method there is. Everyone learns it as trading 101. Thats what they taught us when I went to the CME for classes in the mid 90s after I blew out one of my first accounts at Alaron. To be honest, i still use the method myself to search for good markets to research deeper.
If you follow his calls, and compare them, you will find that method mirrors every call he's ever made.
