Hello Mr Iyer.
You can practically check the facts by writing a formula in your software, based on the VSA. beware it may be the trademark of the software maker, so dont name it as VSA.
Meanwhile I try to clarify myself in words or in theory,
VSA : The recorded volume information contains only half of the meaning required to arrive at a correct analysis. The other half of the meaning is found in the price spread.
Defect : What is the right interval for sampling the spread ?
optimizing wont be answer as it'll just show general tendency, wont complete cause & effect said in the theory.
VSA : The imbalance between Supply and Demand in the market, which is created by the activity of professional operators.
Truth : Its only created by Mr.V by
anybody.
When ever we label the total trade quantity for the specific interval as, Volume, we should not forget that, these are the trading quantities by different entities for diferent reasons leading to different meanings.
And if you are imagining V as a single entity then you have to call it
"Master of disguise"
These things lead to many people thinking, volume have no correlation of price movement, this is not the truth either.
Its one of the three dimensions of the markets.
thanks,
