Intraday charges for old users from yr 2021

Hi,

I created my account in 2021. I usually take Holdings , but I want to try Intraday also. I want to know what are the charges for Intraday in the following conditions:

1. I create a CNC order but want to close it on the same day ?

2. I create a Intraday order and want to close it before 3:15 pm , same day
