Thanks a lot for everyone who replied. All the information
is very useful.

The five elements you combine to make money have a very weak interdependence. Have you migrated to this place by building on former successes?

 

Is this a riddle or advice?

 

One way to decrease the likelihood of curve fitting is increasing the time frame in the optiization.

 

Are you talking about optimizing the new time frame only, or optimizing all the data with the new time frame included?

If it's the new time frame only... well... then... opitimize it.

If it's only including the new time frame, you're insane to expect that the past week is going to provide breakthrough information when you started with 5, 10, or 20 years of data... I'd do it absolutely no more often than monthly... up to yearly, depending on how much effort you put into making sure that the optimization is rigorous (maximal statistical significance).
