Let's talk about $BTW just now: 5 minutes, +2.34%.
The first pullback after a rally is the most important: a pullback on lower volume is still healthy, while a decline on higher volume calls for caution. Here's my usual approach: I don't rush to chase sharp rises or panic-sell sharp drops. I wait for the market to settle down a bit before reassessing.
