last comment: again we should all try to devise our own trading plan, and that may be multiple plans depending on the accounts you are trading, such as a 401K IRA or a trading account, you may have different plans and trading styles for them

The mechanical systems, mean reversion and KISS systems follow hard rules and discipline.  We should probably all be more like the systems as a rule based strategy approach is the best approach to trading. The systems follow their strategy and rules to a tee, whereas we human's tend to waiver and get wishy washy and emotional - it's not easy to set an exact set of rules like the systems, but we should all try to have more of a systematic approach to our own subjective trades, and that starts with sitting down and devising a trading plan and style that fits you - and of course that's easier said than done and can take years sometimes and you go through modifications as you learn and go through experiences
