I am not an expert but just chip in 2 cents opinion here.

Action yesterday can be considered as a way of testing supplies at lower prices. The Market Makers may deliberately sell some at lower prices to create a sense of more supplying at lower prices to attract other sellers to follow suit. This can be considered a final washed out before moving up to the next leg up. A drop with less volume like yesterday will give the Market Makers confident that there is no more supplies at lower prices so now they can comfortably to push the price higher with less resistance.

But you shouldn't rely on these signals like yesterday to judge the action today. There are many false alarms and signals in this game. Always DYOR and stick with your own strategy.
