Plotting Bid and Ask volumes

[fishbed]

Hope this question not already asked, looked through and not seen. So here goes

I am just trying to get the current volume for Bid & Ask plotted.

When I create an indicator using the GetCurrentBidVolume() function andGetCurrentAskVolume() for the other side I get the same values each time.

Am I missing something obvious.

Any help appreciated
