Hi, I have been successfully importing a self-generated scid file since December last year, however, I now started getting an "out of order timestamp" issue. The message is: DAX-LONGSHORT 1 Min #1 | Out of order timestamps detected. Chart tool drawings and some chart studies may not function properly. Prior Date Time: 2022-07-11 08:53:00. Next Bar Date Time: 2022-07-11 08:46:00. Filename: DAX-LONGSHORT.scid | 2022-07-11 08:53:40.074 It seems that the "Next Bar Date Time" is never incrementing. How can I solve this problem? Thank you very much in advance! |

The only possibility here, is that the timestamps are actually out of order in the Intraday data file.

Thank you for your prompt reply! I have already checked the scid file and it is correct. However, when I perform manual re-calculation the out-of-order timestamp (as visualized by the out-of-order timestamp study) disappear except for the latest bar. This is an excerpt of the exported bar data: 2022/7/11, 13:17:00, 0.29, 0.29, 0.29, 0.29, 1, 1, 1, 1 2022/7/11, 13:18:00, 0.29, 0.29, 0.29, 0.29, 1, 1, 1, 1 2022/7/11, 13:19:00, 0.29, 0.29, 0.29, 0.29, 1, 1, 1, 1 2022/7/11, 13:20:00, 0.29, 0.29, 0.29, 0.29, 1, 1, 1, 1 2022/7/11, 13:19:00, 0.29, 0.29, 0.29, 0.29, 1, 1, 1, 1 At 13:18, I did a recalculation and the "13:19:00" timestamp will continue repeating from then on. FYI, I have a Intraday Data Storage Time Unit of 10 sec and I use the SC data feed. As I wrote earlier, I did not have the problem earlier. The only thing I changed was the Intraday Data Storage Time Unit (from tick based to 10 sec). Thank you for your help!! Date Time Of Last Edit: 2022-07-11 11:47:17

Where is the real-time data coming from? The timestamps of that sounds like they are not correct.

The data is generated using a python script I wrote, which creates an entry every minute based on some scraped data. The entries are generated exactly as explained here: Intraday Data File Format As I said, after a recalculation of the chart, all "out-of-order timestamps" disappear. Also, when I try to spot these timestamps using "Edit -> Edit Intraday Data" they are all correct, which proves that the generated scid file is correct. It is only the real-time updating of the chart in SC that does not work properly. |

There must be something you are doing wrong on your side. This is definitively not a problem on the Sierra Chart side.

Dear SC support, Your reply is not really of great help to me. I am not saying that there is a problem with SC. But as I said already a couple of times, my scid file is correct. Probably, there are one or two configurations that are not correct but I don't know where to look and check. I was hoping that you can give me at least some hints on what to check. IMO, if you provide the feature of importing your own scid file in real-time in SC (which is a wonderful feature BTW!) then a customer can expect some degree of support for this feature that goes beyond just repeating that "something is wrong on my side". Please give me some hints what I need to check that could help solving the problem. For instance, I changed the intraday data storage unit recently from 1tick to 10 sec. Could this create the problem? Thanks |

Based upon what you are saying, are the timestamps of written records in the Intraday data file changing? The Date-Time value of a record must not change after it has been written.
