Quote from Instynct:
But for some reason I kept shorting the lows of the range, "blindly thinking that support will break" before it does. Those words are in quotes because they are my words spoken on here last week, yet I went against my own rules. So to reiterate, the rule is this: "Never, ever sell into solid support, or buy into solid resistance". You either buy with the support or sell with the resistance, or wait for a clear break. If there is one rule of mine that I break the most, it's this one.
I am of the opinion that every trader suffers from some kind of problems and some kind of discipline issues. It is good to know the rule that you break the most, because only once you know it, you can work on it. However, it could be really tricky to work on one's weaknesses.
For example, my biggest weakness is I find it very hard to hold on to trades in ES when ES breaksout in a sharp way. I take the trade in the direction of the breakout, book some profits and then reverse. This has caused me huge losses on big trend days. And I find it very hard to control this tendency of mine.
