I can't get a volume based chart to load historical data on IB's datafeed, and the 'Reload historical data' option is greyed out. It's displaying the real time data and updating the chart correctly, but is missing all the previous bars.
Time based bars load correctly though. I wonder whether this problem could be due to the fact that IB's feed is aggregated? Not sure though since this shouldn't affect the volume.
Also, just a suggestion, but the fact that I can't search for words <= 2 characters often makes it very hard to find existing answers to my questions.
Thanks.
