the system does not trade on Thursdays. Its backtesting showed that this was the most unprofitable day of the week.

curvefitting or not, who cares? people get so bent out of shape when it comes to that word
the only problem with excluding thursdays is if thursday's become one of the main money-making days.
the core strategy is profitable with or without thursdays, so if excluding thursdays gives it a boost, exclude them until you see reason not too!
Quote from dougcs:
My testing shows that the Thursday factor statistically is significant at the 90% confidence limit, so I think it is not curve fitting.

Quote from electron:
I believe this is a sound way to do, that is, as you say, until it stops working. But I would use both systems, one without the Thursdays excluded and the other one as in the original work.
The main problem I see with this system as applied to YM right now is not the Thursday problem. The problem is that the daily range in YM has recently shrunk considerably even compared to ES so this system may not work as well as it did in the past until YM regains its previous levels of volatility.
