Why can't AMO orders be placed beyond today's circuit limits?

AMO Orders & Circuit Limits – Explained

You cannot place an After Market Order (AMO) at a price outside the current day’s circuit limits. AMO orders are only allowed within the price range (upper and lower limits) defined for that trading day.

These limits are set by exchanges like NSE and BSE to control excessive price movements and ensure market stability.

Any changes to circuit limits are applied only after the exchange updates them for the next trading day.

Note: Circuit limits for the next trading day are typically updated by the exchanges after market hours, and the revised limits become applicable on the following trading day.
