I just got IB + QT running and I'm having a problem with the intraday backfills. Every security that I backfill on QT, the most recent 6 hours doesn't show up. It backfills the past 5 days except for the most recent 6 hours. Stocks, futures, FX, indices, nothing will backfill for the complete current day. I've tried both running the most recent QT release (3.8.2b) and 3.8.1, same issue on both. The time delay is exactly 6 hours, down to the minute. If I open up a clean chart of the NDX, IB backfill gives me the 6-hour gap. If I switch over the data provider to Ameritrade and re-backfill, it fills the gap. There's no gap on the chart in IB TWS. By process of elimination, itâs something to do with QTâs settings for my IB backfill. Hereâs a pic of what the chart gap looks like on the YM: http://img407.imageshack.us/img407/3715/ymir1.png Pic of my backfill settings: http://img61.imageshack.us/img61/6030/settingsfs3.png The 6 hour gap period is not static either, it begins whenever I open up a fresh chart. If I were to clear the YM chart and re-backfill, Iâd have a 6 hour gap directly preceding the real-time tick. All feeds are set to IB, everything else is working fine. Quotes, historical backfill, eCBOT open book, etc. Just the 6-hour gap on the intraday backfill. I've searched these forums, quotetracker.com, qtusers, google, came up dry. Any help would be greatly appreciated!
