The CHX event is crazy.

If you were someone who had yesterday learned that a large volume order on the CHX market is followed 60-90 minutes later by a large increase in price you would have very easily been able to trade today's event.

obviously I don't think this is very common knowledge but the fact remains, if you learned this information yesterday, then you could have acted on it today. IDK whats going on but I can say that any predictable movement made on the lit exchange is the last thing wallstreet wants, being predictable = being vulnerable, and boy oh boy does this look like vulnerability to me.
