Cache Service

This application installs as a windows service and runs in the background to build and manage a cache of recent off-hours stock values that are not otherwise available from the Xignite API. 

The cache is intended to keep data to service requests for the current day up to the previous 24 hours.

Installation

A installer app is provided that installs and starts the service automatically. If uninstalled the service will be stopped and removed. You can see the service running in the Windows Services list.

This is what the properties page for the service will look like. 

Removal

If you need to remove the cache service you can easily do this using the Control Panel - Uninstall Programs option and remove the Xignite Cache.

Logs

The app will write logs for each day it is running to the ProgramData folder: 

📁 C:\ProgramData\Bannister Lake\Xignite Cache\logs

Settings

Some settings are saved in a settings file in the ProgramData folder

📁 C:\ProgramData\Bannister Lake\Xignite Cache

Backup

The list of stocks and current cache data are saved to a backup file in the ProgramData folder.

📁 C:\ProgramData\Bannister Lake\Xignite Cache

This allows the service to be stopped and restarted without losing data that had already been accumulated. However if the service is stopped during off-hours you may miss out on stock values that occur while the service is stopped.

Stock List

The list of stocks that are selected for off-hours caching are saved to the 📄 stocks.txt file in this folder:

📁 C:\ProgramData\Bannister Lake\Xignite Cache

If already you have a list of stocks that you want to use from another machine or say a copy of the ticker stock list - you can manually edit this file and when the service is restarted - it will read the list and start caching all stocks in the list.

Command Line Control

The service can be stopped and started using windows command line statements:

:: STOP service
net stop BLXigniteCache

:: START service
net start BLXigniteCache
