monday August 22...share price plunges 40 % ???

I see my portfolio shows a plunge of about 40% today....from 2.30 area to 1.22 ,(on last Friday ?) or is it today? Ive learned to ignore the share price in the recent months...it seems to go up and down willy nilly. Today I look at the schwab account and it says only 10 shares traded. its all screwed up....but on my portfolio its making me think I'm down a few thousand dollars on my shares.

I have no idea what causes this kind of irregularity. I expect to see price return to the 2.20 area again,but its a bit disconcerting to see what looks like thousands of dollars "in the red" from HRTPY.
can anybody explain why this happens all the time.

I've come to just ignore the share price for many months because of this.
Is there any real liquidity? can I some day sell 4 thousand shares and actually see the transaction go thru ?
