To my knowledge: Holsinger was/is 100% mechanical systems' trader. He wrote some programs that clicked during certain market conditions, but like most/all systems trading it is a constant state of evolution. Sakaeda is a trend-following trader, takes positions in a basket of commodities based on seasonal patterns, other tools and hangs in there for the ride. When he catches a trend move, it really ratchets up the result. Sometimes holds a position for months, thru (what may be) frightening drawdowns and high unrealized gains that slip greatly along the way. I'm not sure why either/both haven't outperformed recently... lots of trends in commodities, although stock indexes have been a challenge for mechanical systems. Each guy has made a lot of money in real-time wins, years past. The leader-board is fresh this year.
