I often here and see statements like this.We always rely on research when making trading decisions. The research has indictated that volume has little to do with price. However, strong up days combined with high volume-- specifically largest up day in 10 days combined with largest volume the returns over the next day were up .25%, next week up .60% and next month up 1.45%. This was the only edge the research discovered in using volume
What is an edge?
Is it seen as better than 50% success rate.(You dont need + 50% to profit).
My own definition is Longterm Income > Longterm expenditure.
How you derive/achieve that is entirely up to the individual.
I believe this applies to any Wealth Creation Endeavor (Business/Property/Trading).
