I'm writing to ask for assistance with an issue I'm experiencing when opening my chartbook: the charts take a long time to load, likely because too much historical data is being downloaded. I would like to configure the system to use the historical data already stored in the local database and download only the most recent missing days. I’ve already read the documentation at: https://www.sierrachart.com/index.php?page=doc/ChartSettings.html, but I wasn’t able to resolve the issue. Could you kindly guide me step by step on how to properly set the charts to speed up the loading process by using the local historical data? Thank you in advance for your support. I look forward to your reply. Best regards |

This is what the system does. There is nothing that needs to be done to enforce this. From your video, the issue is not the data being downloaded, but just loading the data into the chart from your drive. From the following link: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often: 30.1 - Too Much Data to Load or Loaded The amount of time it takes to load Intraday chart data with a particular Days to Load setting, is affected by the number of data records in that data file. The Global Settings >> Data/Trade Service Settings >> Intraday Data Storage Time Unit affects this and also the frequency of trading for the symbol. If the Intraday Data Storage Time Unit is set to 1 Tick, and there is a lot of trading that occurs for a symbol, it will take longer to load Intraday chart data compared to a symbol that trades less frequently.
Also, take note of the information given in 30.12 - Intraday Data Storage Time Unit. Historical Data Time Frame. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |
