Sivart. A crucial facet of successful trading is identifying low risk entries. Going short at a failure to break resistance (or long at a failure to break support) would be a low risk entry. We're talking about swinging the odds in our favour.
I have no bias in my trading. I am not attached to either going long or short on any single stock. Winning is about selecting likely direction and acting on it. Not willing it to go up despite it likely to go down (or vice versa).
Going long at $3.15 was riskier that going short. Support and resistance tells us that. Until that trendline is broken I'm afraid all we have is a counter trend rally.
