NVSR Looks like a double bottom, one at .016 and another at .018 (the bottoms don't have to be exactly at the same point, but reasonably close to one another). Both bottom days were nice volume days, too.
I also noticed the MACD crossed over its signal line in mid-June, a few weeks ago. This is a lagging indicator, but for it to cross before any noticeable price increase is significant.
All IMO.
