LG, that's very, very interesting, thanks...i have so far concluded that a quasi-mechanical system is the best approach based on three principles:
(1) determine a number of specific patterns and indicator readings with high probability of success for trading long or short
(2) use findings in (1) to make daily trading decisions based on visual inspection of charts
(3) keep checking if findings in (1) still retain their validity as the market evolves (for example, bull markets and bear markets seem to have different patterns that work best in each of these)
These principles could be computerized up to a point but imo a computer program would not work as there are too many variables that have to assessed in their totality...as a result i believe that any such system has to be "manual" where the trading decisions are based on visual chart inspection..
Still, i believe that chart/pattern/indicator analysis is the best use of my time so my trading can be as "automated" as possible (this is also crucial to self-impose the needed trading discipline)..
LG, do you use a "system" of sorts for trading?
