Admittedly, would I miss the runs you named just based on a technical indicator? Sometimes, fundamentals trump technicals. Sometimes, depending on the time and the belief of the timing of the fundamentals, technicals trump fundamentals. Just guessing, I would not have passed on a trade purely because of failure to fill a gap. I might have passed on a trade because the RSI was over 80. Hard to say. I don't know if I would have passed on news being priced in. Depends on the quality of the news. Some technicals, however self-fulfilling they may be, have statistical importance to occur more often than not. As a strategy, it is better to play the percentages. I probably would have, despite missing an occasional gain.
