After cross-verification on our end, we observed that in yesterday’s trade history, you initiated an NRML Buy order on 16-Aug-2023 at 15:17:40. However, during the process of closing your position, you attempted to execute a sale under the “MIS” category. Consequently, your order was rejected, and the reason provided was “RMS: Auto Square Off Block.”

In accordance with our policy, all “MIS” orders are subject to certain time restrictions. These orders can only be placed within the specified timing outlined below. It’s important to note that any orders falling under the MIS product type must be exited before the market’s closing time. Failure to do so may result in an automatic square off of your position by our RMS system.
