I'm testing the SierraCharts RT data feed with my current IQFeed. Volume matches fine, but I am noticing discrepencies on a delta basis, and minor differences when charting volume bars, indicating timing differences. Today (15-Jan), by 10am CET, SierraCharts shows a negative delta of -5700, whereas IQFeed has -9600. I am not making claims to which datafeed is more "correct", but I want to understand the possible reasons for the discrepency here, given that IQFeed is seen as the standard for retail data feeds. I use delta momentum as a potential entry filter, so this is important. Attached a small spreadsheet with my findings
