Can anyone tell me how to use scanner to scan 50 scrips at a time

you can use zerodha pi to do so…first go to alerts menu in zerodha pi and click on scanner then click on edit script button and then click on add symbols button and select the script and click on add button keep adding all 50stocks finally click ok. finally click on load button. this will apply scan alert on all 50 stocks.

But i apply this it is not scanning it shows the same result
