BTC.D - Bullish Retest & Bounce Incoming?

With BTC strength reducing as it hits resistance at the top of the bear channel , we also have potential confluence with BTC .D potentially about to do a bullish retest and bounce from the macro falling wedge it broke out of early in the Spring .

Naturally a retest and bounce points to another batch of selling off for BTC and crypto as a whole.

Any thoughts on how this idea could fail?
