Do you know how to look at level 2 and see the support? The answer for OTC is pretty cool.
Google "OTC markets" and PVCT. It will show the bid and the ask for each market maker and the number of shares. Today it was like watching a football game. You could tell where the defense was thin, and a big gain was in the making. You could see retreats, too, just like the one that occurred at the end of the day. Today was nice, because the offense gained a lot of ground!
