What should be the values of Periodicity, Bar Interval and Days IN SCANNER?

Suppose I want to scan my code on a 1 min live candle chart using SCANNER.

What should be the values of Periodicity , Bar Interval and Days?

Will it continuously keep on scanning?

What is the time interval between two successive scans?

What is the max no of symbols I can add in scanner?

you can use 1 minute periodicity with bar interval as 1 and 2days

yes it will keep on scanning on live market data

maximum number of symbols is based on your system and network speed and performance ,
you can check with 10 symbols initially.
