I wasn't sure, really, where to post this. Sorry if I picked the wrong place. It does involve charts, but I don't think charts are really the issue, but I needed a place to begin, and, well, this seemed like the best place to start.
I am running version 7.0/1000.10 on 32bit WinXP, Rithmic data from Vision and have had no issues so till now, and, no issues with Nymex or Globex symbol based charts. I have charts of Treasuries, Currencies and Indexes up that are working fine.
The problem I'm having pertains to Comex metals data and charts from them. When I call up a chart for, say Dec Gold, the part of the chart that would have already occurred (recently past data) seems spotty in the same way a thinly traded, further out chart would look. However, the part of the chart that forms while the data for that window comes in live seems to form normally. If I go to another instrument and come back, the correctly formed bars are gone and replaced by small range/no range bars like the previous rest of the chart. Again, new bars form normally. Also, the thin bars for Gold are the same for all of the Golds, as are Silver for Silver, or Copper for Copper. And, the x-axis labels are advanced by one minute, ending on '6' and '1', not '5' and '0'.
I made a Market Analyzer window for Comex Gold, Silver and Copper, all contracts from 9-12 to 3-13, and included a column of 5min Vol as an Indicator column. While the DailyVolume column data seems to be sensible, the 5min Vol data (column heading of 'Vol') does not seem to make sense, with all the GC contracts being 1, most of the HG contracts being 325 and the SI contracts being 6 or 8.
I called my IB to ask if this might be a data provider issue because it only seemed to be happening with Comex symbols. He thought it might be an issue with the expiry date or rollover date being incorrect.
Here are some images to show what I'm talking about. Note how the last 10 bars or so of Dec Gold look pretty normal, but the bars from before don't. Also, the x-axis on the chart, and the Vol column on the Market Analyzer.
Thanks for any help in advance,
Chris
