I subscribe to the SC real-time data feed. On my ZN futures charts there is an incorrect price gap as of 12AM EST on 2/27/15. The bar closes at a price of 128 11.5/32 as of 11:59:59PM and opens at 127 22/32 as of 12:00:00AM. I have the chart settings at "Continuous Futures - Date Rule Rollover." I have also used "Delete and Download All Data" but the problem is not fixed. Please help.

I tried the procedure described but there is still a gap. What can I do now? I have deleted all ZN related files and the gap is still present.

Why is this incorrect? We see the same values.

When we set the rollover to back adjust, then these are the calculations:
ZNM15 [CB] 30 Min #3: ZNH15 Open price on 2015-02-27 is 128.2344. | 2015-03-05 18:41:37
ZNM15 [CB] 30 Min #3: ZNM15 Open price on 2015-02-27 is 127.5781. | 2015-03-05 18:41:37
ZNM15 [CB] 30 Min #3: ZNH15 price difference to ZNM15 is -0.65630001. | 2015-03-05 18:41:37
ZNM15 [CB] 30 Min #3: Back adjust amount for symbol ZNH15 is -0.65630001. | 2015-03-05 18:41:37

So the gap you see is correct. If you do not want to see the gap, then set the Continuous Contract option to date rollover back adjusted.
