volume traded per candle

How can I see the total forex market's volumes traded per candle?

When I move the mouse over a candle, it is clear that I am only seeing the broker's volume, not the total forex market's volume.

I see many figures bandied around about 2-4 trillion dollars a day traded - that's 20-40 million lots a day traded.

But I see no central point where I can verify this.

And given the sudden and full price swings from time to time, I very much doubt that such market movers exist that can push price action 100 + pips in 5-15 minutes if there really is 2-4 trillion dollars a day traded.

If you're using MT4 then you cannot see the market depth, you'll find the depth when trading with ECN Brokers like Dukascopy or MB Trading.

Try their demo accounts and see the market depth in real time (but not the whole depth).

eSignal claims to provide consolidated volume (actually tick info) data from a number of brokers. Have heard some good things about it, but the people may have been motivate to say that. Its not free; I think the monthly fee is $100 and I can't remember if that is additional to the basic feed or included.

in normal market operation volume can be exhibited by candle length generally ... with spot prices your never going to get accurate volume numbers.
