"So, when Shorts as % of volume is 18.99%, does it mean 81.01% is long and most of people (81.01%) bought share?"
I would say yes, but will accept a different answer from someone wit more experience.
"Is it correct to think this share would go up as more people bought rather than sold?"
Yes...and no. It would be an 'assumption' that based on the majority sentiment that a stock will go in a particular direction. But often they (stocks) have a mind of their own. So get your trading plan sorted out and your protection in place (stop losses etc) in case it goes against sentiment. So I understand that following the crowd seems logical and sensible but even the crowd gets it wrong. In the end the share price movement itself should be your final decider. (IMO)
