Zerodha Pi Scanner

Dear Sir,
Zerodha Pi Scanner is very cool feature. I created scanner for me however, next day they not in the scanner list? Why is it so? Can’t we save a scanner permanently once created??

yes. You can save it by giving a name.

Even though I saved the scanner by name, it was not available next day??

if there is F&O stocks in the list than up to next expire you can save. after expire you have to save it again.

Then why it expired in a day??
