The future is an echo of the past. Understanding how time works, what patterns repeat, within what bounderies reality or trading plays is key to predicting the future. TA is not a golden ticket to know the future, it is an excellent tool to provide us with a good rational idea of where potential resistance and support in the future may lie. Apply some probability and we can make a good average guess.
I put these three historical events next to each other so we can learn the correlations and get a better grasp how to react and trade.
What I see is that once we make an all time high, the .618 levels is an important support level and when broken some serious dumping occurs. See what correlations you can find yourself, hope it helps!
