Look at it this way, for every trade you got three steps:
>Devise plan (including your stop loss)>Execute plan (where you need discipline and/or judgement)>Review plan (including when you might re-enter)If you want to get better, you bring as little chaos to the execution part as possible. Then you can more simply decide whether selling at 150 was a good, rational part of your plan.
