I described all the options with the thoughts that actually go through my head. But in reality, I know the right answer, for me anyway, is #2. I believe I have to transcend the psychological barriers to trading success. This is a must. If the markets change and my systems require tweaking, sure, reduce size until consistency returns. This is where a thorough biz plan, accurate records and statistical analysis are critical.
...but if I skip a signal, or lose on signal I took, what is the difference? They both result in X less acct balance. If I miss a valid signal which succeeds, then take the next valid signal, which in turn fails, I have still lost X. It's essentially a basic axiom of trading - take all valid signals.
In Ari Kiev's book, "Mastering Trading Stress", he cites this to be a common mistake, even at the hedge fund manager level.
The idea is this: Develop a goal which you believe you can achieve. Develop a system/approach which has a feasible chance of attaining these goals. Now, the system dictates position size, valid signals, money mgmt etc. At this point, focus on the setups/system, not the money. The monetary goal IS used in the system development, but should not be the focus thereafter. The only focus should be consistency and loyalty to the system. Any reduction in position size should already be a predetermined element of the system, not based on current emotion or stress.
Easier said than done, but since when was trading easy?
As a side note, the markets close at 2pm where I live, so I go to the mountains everyday, anyway.
