Lower circuit auto square off

I have a doubt, let say i have 500 rupees and using leverage i got 50000, so instead of 1 share now i have 100 shares of 500 rupee each…and let say @3:19 pm the share hit lower circuit(which mean i cannot sell share) so at 3:20pm how will auto square be done ? selling of shares is not allowed.

If it has it Lower Circuit then even RMS will not be able to square-off your position, in such a scenario your position will be carried forward to the next day under CNC. If you do not have enough funds then your account will result in a debit balance and you will have to add funds. You can learn more here.
