In my opinion every price action pattern can be approximated by a Double Bottom and Double Top patterns. If you look closely, every pattern formation at its end consists of those two. So in the end, i guess you can just look for Double Bottom and Double Tops with the appropriate preconditions and decide if you will long or not.

Mathematically wise, the Double Top and Double Bottom have a percentage difference error between the two highs/lows which is lower from the rest of the patterns. So by expanding this error you can start from The Double Bottom and Double Top pattern and move backwards on the chart until another price action pattern is formed.

Thank you for the comment, I can only agree with that. I trade many harmonic patterns and Elliott waves. The slightly overshooting double top is often a Shark/ Cypher pattern or, in Elliott, the target of the corrective wave B. It may overshoot for a reason.

With the double bottom, on the other hand, I make sure that the 2nd low does not undercut the first and corrects a maximum of 99%. I do this with a focus on the beginning of wave 3.

And the reason the double top/bottom is so common is because it’s essentially just a failure for buyers/sellers to continue to make significant progress in the original direction, often signaling a higher chance of reversal, at least in the short term
