True its currently showing overbought but from May through August it was oversold and while you would expect a bounce during that period none occurred. It would not be a surprise for there to be a pause in the PPS's rise but also it would not be a surprise if it continued to go over $1. There simply is not enough of a float to have an efficient market in NAVB currently, so as far as I am concerned TA is off the table as far as traditional RSI et. al indicators are concerned.
The PPS is acting as though news is leaking, JL may have tipped his hand too.
