Hello Sierra Chart Support, I am having a recurring problem with chart data not loading correctly in Sierra Chart. This issue happened previously, appeared to resolve, and has now suddenly returned. I have already done extensive troubleshooting, including: * Disconnecting and reconnecting Sierra Chart to the data feed. * Restarting Sierra Chart. * Reloading the affected charts. * Closing and reopening the chartbook. * Allowing the historical data time to download. * Checking the futures symbol/chart I am using. * Trying the connection/loading process multiple times. * Checking whether the market itself was still producing data using another trading platform/data source. * Confirming that this is not simply a temporary market-data delay. * Testing the chart again after it previously started working, only for the same loading problem to return. The chart was previously working and displaying the data I need, including my footprint/Numbers Bars information. Then it suddenly stopped loading/displaying the data correctly again. I have attached screenshots showing exactly what I am seeing when the problem occurs. Because this problem keeps returning even after troubleshooting, I would appreciate help identifying the underlying cause. In particular, could you please determine whether this is related to: * Historical data downloading * The data-feed connection * Symbol mapping * Chart/data settings * Numbers Bars data * A corrupted or incomplete data file * Or another Sierra Chart configuration issue If necessary, I can also provide my Message Log, Trade Service Log, chartbook, exact symbol/settings, or any other diagnostic information you need. I would really appreciate someone reviewing the screenshots and logs rather than having me repeat the same basic troubleshooting steps, since I have already gone through those multiple times. Thank you. |

Are you using Wine or Linux or Mac for running Sierra Chart on? We see one of the errors. That is extremely unusual to have a compression error. It indicates a corruption of data over the network. Which should be impossible to even be occurring. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Are you running any third-party (non-Microsoft) firewall or security software on your computer? Are you using any custom studies? In other words, other than the Sierra Chart provided built-in studies. This is not a problem within Sierra Chart itself. There is an external issue causing data corruption, of data received over the network. Make sure this is also set to No: Global Settings >> Sierra Chart Server Settings >> General >> Special >> Use Single Network Receive Buffer for Linux Compatibility : No Sierra Chart Support - Engineering Level Your definitive source for support.

Whole month of august is missing except today. Other times, it will be missing July as well. Rarely all the data loads. It's a coin toss. Really need this data. |

The error log now says something new. "Record has been filtered due to large range while loading intraday data for NQ"

There is something wrong with your computer system or network connectivity. This simply is not normal and should never be happening. We recommend trying another computer. The error given in post #7 is because the data is corrupted. Delete the chart data file for the symbol: Chart Data and Chart Data Files: Deleting a Chart Data File However, try a different computer. Something is definitely wrong with your system. This is with certainty. Or with its network connectivity. Sierra Chart Support - Engineering Level Your definitive source for support.

Now I can see all dates out of nowhere, but the last 15 minutes of data is not shown, and there's no movement on the price. I would like compensation for this purchase. I'm not able to use it for the past 2 weeks. |
