I'm a trap trader but I personally don't believe in BS like "bullish volume", "bearish volume", because for a buyer there is a seller. And newbie traders who buy high and sell low generate massive volume nowadays too. But when big volume with (pattern, media, rumor) bias gets trapped, that's when one side has to take an immediate action altogether (thus moving the price).
On TSLA it just happened. Friday close took out the previous "blown top" candidate. And look at the volume of those candles... Today's gap further confirms it. But bullish for how long? It's at the mercy of those TSLA buyers down there.
