Order flow is certainly important as well but it is not always available in some instruments (the CFDs one I trade). Even so, we can still infer good short-term context from just price action.
Maybe this would get Volpri's approval. How Volume happens, matters. Likewise how prices are reached matters. It is in the details. Hence since you need to see the details in price movement, you can also discern the volume details from that same "look see" process. Add to that you need to do it fast and accurately and consistently, regardless of the number of repetitions, doing the "two birds with one stone" method is often advised for short term trades where entry needs to be immediate, IF warranted. Personally, only Volume extremes catch my eye, by that I mean a cumulative series of blocks or some huge blocks. They often portend a climax. Otherwise it is price action.
Prolly because he read some of my posts... I've disdained volume for years and recommended traders "fuggetaboutit". Volume analysis is worse than worthless... it's actually harmful to trading success. (I know... I'm a heretic. Correct nonetheless.)
my point is you can trade by only looking at price....... can you trade by looking at volume ALONE....without looking at price. i doubt it. there used to be a trader who used to trade by looking at CCI alone
David Fuller, who started trading when he was 17 and now is above 70, founder of FullerMoney.com called volume a 'fickle indicator '.
I wouldn’t carry disdain around for it but I just don’t think I need it for the way I scalp and it would just cause me to not take some trades when I should and to take some trades when I shouldn’t. However, it isn’t entirely useless IMO.
