"Up Volume, Neutral Volume and Down Volume"... It doesn´t mean anything for me. What is important now is that for every share sold there is someone who is buying it: So if there is much volumen, it means there is much interest.
It would be a problem if there are a lot of sellers and no buyers. What is important is that there is someone or some people who is buying PAVC shares at this PPS level ($50.000 of trading is not a joke in this POS).
