I would have to disagree that the resistance at 12k is "an impenetrable selling wall".
I don’t believe 12k is a barrier either.
Trading isn't about predicting which way it will breakout but rather recognising it when it happens and then reacting quickly to that.
I rather believe technical analysis is more useful to understand the past. Trading predictions massively fail, and that’s why 95% of traders lose money, but when you say traders recognize a pattern and react, I think they contribute to the changes: they believe it will go up, thus, they buy, and price goes up. They believe it will go down, they start selling and more panic comes, dragging down the price.
The title itself it’s quite revealing “Why we
may…” So, I think we may or may not.
