just to clarify, I think that's 90 trading days, so that's about 4 1/2 calendar months of trading, not 90 calendar days. Will take more news and getting to something like $5-6 range for a long period with no dips.
On TD Ameritrade I show close at 4.30 bid 4.34 ask. One TD Chart software module showed a spike to 2.98 then close at 4.30 but only when viewed on a 1 yr 1day chart setting. All other chart time periods dont show any spike. Plus the other main TD chart software doesnt show it at all when viewing every trade at 1 min intervals. So looks like spurious data point in one database. I've had this happen in other stocks too with some wild data points which I've seen then disappear in a few days, maybe somebody does database clean up at certain periods. It would actually be nice to add shares at lower prices and my bottom end buy price for the uptrend starting in August 2014 is currently at $3.42. Volatility is to be expected in OTCBB Biotechs.
