Short answer

Your pinned overview resets to the default Nifty and Sensex when your browser cache changes or gets cleared, as Arrow stores these preferences in your computer’s local memory. However, you can change the pinned instrument to your preferred stock or index.

Common causes of cache changes

Your pinned overview resets when you:

Clear your browser cache

Reset your browser cache

Use a different browser to access Arrow

Log in with a different user ID in the same browser

Have browser settings that delete cache when you close the browser

How to prevent automatic reset

Check your browser settings and disable the “Keep local data only until you quit your browser” option if it’s enabled. This prevents your cache from being deleted when you close the browser.
