A quick summary after 3 weeks:
Something seems to be wrong. Basically, after I miss the entry, the market then runs away.
YG: twice missed my entry point by a fraction of a point. If I got in both times, the profit will be +6, while the buy and hold profit is +8.
QM: missed my entry point by 0.4. If I got in, the profit will be +0.5, while the sell and hold profit is +3.
ZF: +4/32 vs. + 1 1/32.
ES: if the market drops suddenly, the same problem may happen.
So far, my bias has proven right for YG, QM, and ZF. Yet, very little money was made on these. I think I know what the problem is. The experiment on each contract will terminate when the bias on that contract is reversed, at which time the two approaches will be compared. I have a strong feeling that the buy/sell and hold method will win out, but I won't draw any conclusions until the time comes. There are still weeks or even months for things to possibly come around.
