I am looking at the December 2005 Dax contract in eSignal. On 12/16/05, the 1 minute chart says the open at 9:00am is 5303. the 5 minute chart says the open at 9:00am is 5306. Why is there a difference? Can someone who has another data source confirm the opening price for that day? Thanks. I am attaching the screenshots. Here's the 1 minute chart.
