This plugin allows you to track the changing value of specific items you have in your bank through simply opening up your bank interface! This plugin only uses local tracking, so historical data from the time before the installation of the plugin will not be available for viewing.
The configuration is scarce so it's easy to get going. Pick a time range over which you want to see the change in price your items have experienced. The plugin will show the difference of current item prices to the oldest datapoint within your selected time frame. The percentage value shown is a difference in UNIT price of the item, not the evolution of how the entire stack's price has changed.
The plugin works by creating a timestamp of your bank every time you open up the main tab, up to a maximum of once per hour. This data is saved in .runelite\bank-value-changes\priceHistoryData.json
