Robert Ratcliff, founder of Strike Algo and Capital B28

Robert Ratcliff has been a professional trader since 2013. Like many traders, he spent years making decisions on emotion, winning some and giving it back. He rebuilt from rock bottom to trading eight figures of capital, and what got him there was taking emotion out of the decision.

Strike is that idea turned into software: a rules-based momentum system that runs in the client's own account, with every number independently verified.
