I agree. This is why many successful system traders advise to keep their system open and flexible, the less variables the better. This is also why higher timeframes work so well vs. intraday trading. I have 3 working systems and they do a nice job of capturing the essence of the market direction with only 1 indicator and price is the other indicator over time.

I discretionary trade because my mission is to understand the markets as much as possible before getting more into system trading. I want to know how the market works for myself before building more. Took me 2 yrs to come up with 3 systems so I figure my learning curve in building them would increase as my discretionary gets better.
