Why do you think this pattern works, regardless of the timeframe?
I was thinking about your question a little more. Here is an another interpretation of the topping corkscrew pattern:-
As you said, you could think of the corkscrew as two patterns. On the left (rising flag), there are these consecutive HHs and HLs, price in clear uptrend, and a degree of
regularity. The herd is long. The desire to be right means that the only game in town for the masses is playing the uptrend.
But then the sudden drop from highs, which takes out the three prior lows, changes everything. Momentarily at least, buying vanished. What happened there? The regularity is no longer there and confusion reigns. So we get this chaotic type behavior with the formation of an ascending triangle. The market is grappling for new direction, but without conviction. So you get these false breaks in both directions, and an increase in volatility. The up trend has finished but the market is still in a transition phase.
However, the rising volatility eventually puts the herd under enough pressure so that they start to throw in the towel. The prior state was
regularity and an uptrend. The new state is
irregularity and a transition towards a downtrend. When the price fails to reach the extreme highs and the rally fizzles out, the transition has completed and a more
regular downtrend will start to emerge.
