There in lies the problem.
If it is a viable strategy it should work for everyone. If it doesn't work for you it is very probable that you are the problem, not the strategy.
It is said that you have to find a strategy that you are comfortable with, that fits your personality. But is it possible that what you are comfortable with doesn't work.
You cannot remove bias based on how traders think. So, you could give a trading system that works but, in the hands of another trader, it fails miserably. Each trader has their belief system which like it or not affects their results.
