What the OP graph really tells us for the recent days is that cash is flowing in much, much more than out. It doesn't really tell anything about being at a turning point or not. A whopping one preceding incident of money flow meeting price equaling crash doesn't establish a pattern. No matter how cool of an arc the data draws.

Disclaimer: this doesn't mean that it couldn't be a turning point. I'm not in the business of proving negatives.
