I was fiddling round with some strange volumespike. It gets printed always in the last completed minute bar. I clear the chart data, backfill again, if it was at 20:37 before, now it's at say 20:39.When I stop quotes, clear data and backfill it's gone, as soon as I restart the quotes I have it again, only the time has changed. Sometimes it comes with a price spike down/up to the previous day's close. Sometimes I can get rid of it simply with trying often enough. Sometimes it drives me crazy. The latest occurance I had right now in the GLOBEX EURUSD (6EZ5), with all volume prints being 1 to 3 digits except for one being 31176. After data clean and re-backfill its 31342 in a different minute. It renders the volume profile completely useless. Does anybody experience the same? Do you have an idea what the problem is? I tend to think it's IB rather than Quotetracker who's got the bug. But I'm not sure. I have another issue with Quotetracker's VWAP. It starts at 0, coming slowly closer to the actual price only several hours into the trading session. As far as I understand VWAP it should start out with the actual opening price, but definitely within the developing day's trading range.
