I guess that's what Victor was also saying. However, my Metatrader feed is giving me some numbers under the volume heading.
Also this article refers to it in a currency context:
Forex Technical Analysis Articles - Volume based indicators - Volume - CMS Forex
e.g. "Volume measures the “worth” of a market move. If a currency pair has a strong price move either up or down, the perceived strength of that move depends on the amount of volume for that period. Moves backed by higher volume are more significant...."
However, it also says in:
Forex Technical Analysis Articles - Volume based indicators - Importance of Volume - CMS Forex
" Difference between Equity Volume and Forex Volume:
Volume is different in Forex than in equities. In equities every share traded is considered 1 volume, so selling 100 shares, and conversely someone buying those 100 shares counts as 100 in volume. In Forex the market is decentralized and it is impossible to keep track of all the amounts and sizes of contracts in a given day. Instead the way volume is measured is to count how many ticks or changes of price there are throughout the session. There needs to be a certain amount of contracts signed to move the price one way or the other, and each tick represents this amount. Therefore volume can still be measured, even though it’s a little bit of a roundabout way compared to equities. ....."
I must admit, I was not quite sure what to make of this, but perhaps it suggests that in Forex, it is really just another reflection of price moves.
It then goes on:
" * Volume should be used as a corroborative evidence of a trend, not as primary evidence.
* Volume can be used to confirm price changes. When a trend starts, and there is not a pick up in volume activity, that may mean that the trend is weak and does not have commitment.
* Secondly, if there is a pick up in volume, then that may mean that a change in price may be approaching. The direction of the movement during this increase in volume can be indicative of the upcoming action."
So I'm still left a bit puzzled, really
