Saving Bar Data Locally (Disk Cache)
If you often build the same bars, you can build them much faster by saving bar data in a local
disk cache file. While you’re using CQG, bar data is saved in memory. When CQG IC closes,
bars stored in memory are moved to the disk cache.
CQG IC saves data for:
• non-regular bars - TFlow, CVB, Tick, Point and Figure, and No Gap
• regular bars - intraday and historical for a single contract
• regular and non-regular bars for synthetic spread contracts
• regular and non-regular continuation bars
• regular and non-regular bars for inverted contracts
• regular bars for expired contracts
• regular bars for delayed contracts
You decide how much data to save and where to save it.
Bar data is not included in the import or export of components and pacs.
Please note that bar data is deleted if CQG IC is uninstalled or if you change versions.
This feature requires an enablement.
To set disk cache parameters
These parameters tell the system where to save the disk cache and how much to dedicate to it.
