Each point in his table uses futures. With a large contract, one point is $250. I believe someone on that forum reported the other day they pay $3 round trip.
I've never seen anything like it. Ask Larry... I'm a huge skeptic of market timing... but this guy is doing it well in real time... with enough buys and sells to put lucky coin flippers in a sweat too...
As for account size... nobody should even attempt trading unless they have a large "core and explore portfolio" and only expose their smaller (5 to 20%) "explore portfolio" to the risk.
