When I load a long term chart (10 years) of hourly data, I have noticed that some periods are not shown correctly on the chart. I have loaded 1 hour ES data on the chart going back to 2008. Take a look at the column (DB) highlighted in yellow and chart also highlighted in yellow. There is almost 200 points difference for the same day/hour. The data came from IQ feed and is accurate inside DB, but wrong on the chart. The market on November 21, 2008 was in mid 700s range, but the chart shows mid 500s range.
Thanks,
