BTC Inverted Lookback

This might look like a bottom pattern but use own diligence. *Not trading advice*.
What do we have here? Expanding wedge. This chart is upside-down, let's say, to remove bias...

Price hasn't broken down below, at this writing. So maybe it holds?

The graph could range along the bottom for up to a week if this is anything like the prior event highlighted on the chart.
Unsure about the broadening bottom 0-A-B-C pattern. Trying to learn. But trend reversals often play out that way.
And the pattern would trace a compelling route along support/resistance lines. Let's see if the prediction is even close.
