If there is a margin shortfall in your Upstox account, you will receive notifications via email and SMS from the Upstox team. You will be prompted to add funds to retain the position or close your existing position. To address the margin shortfall, it is necessary to add the required funds to your Upstox Trading account.

Adding funds is crucial because the position you hold may be in a loss/negative, and maintaining sufficient funds in your trading account is mandatory to avoid a square off.
