[amibroker] Index Volume

[burlap58]

I'm getting volume data in real time quotes for indu.x but not other
indexes such as compx.x. Is that a software problem or a data provider
problem. I have the problem with both Iq feed qp rt. I'm trying to use
indu.x in an exploration, but the data does not keep up with the real
time quotes. Would appreciate any suggestions. Thanks, Lloyd
