Three Reasons Why Most Trading Strategies Fail

MAIL BOXI wonder how would you rank order market selection, setup/entry timing, protective stop, trailing stops/exit and position sizing in terms of overall importance to the success of a trading system?

A:  Each are important, but in analyzing numerous strategies I have not seen a tried-and-true ranking system that fits everything.

The reason I think (and my research proves out) that why strategies fail are directly related to three main things: 1) user error (i.e. failure to act on the signals provided by your system in a consistent manner without trying to outsmart the system, 2) over optimization and use of extensive leverage, and 3) the most important of all – little to no risk management through proper position sizing and stops. All in all, if you really are focused on improving yourself in 2010, the first place to look is risk management as it has more of an impact over your eventual success or failure than anything else.
