How soon is the amount used for intraday trading credited back to ones account along with the profit/loss?

Also, theoretically, how many transcations can one execute in intraday trading in a single day with the same amount ?

You can execute as many transactions as you want in a day, no limit on that. As long as you haven’t created losses to wipe out your account in a day, you can trade as much.

If there is a loss while intraday trading, it gets debited immediately. If you make a profit, it gets credited to you on T+1 or the next day.

Thank u Nithin sir for the swift answer.
