Trading is temporarily restricted on this contract or stock on Kite

Sun, 21 Jun 2026 00:00:00 +0000

A “trading is temporarily restricted on this contract or stock” message on Kite means fresh trading in that instrument is paused or constrained for a defined window, and the cause is one of a small set of exchange and broker mechanisms: a volatility-driven exchange halt, a circuit limit hit, a tightened price band under the Additional or Enhanced Surveillance Measure, the periodic call auction category, or a Zerodha block on an illiquid or far-dated contract. The word “temporarily” is the key fact: the restriction is time-bound, lifting when the halt period ends, the next auction session opens, or the surveillance stage changes, not a permanent ban on the instrument.

Periodic Call Auction (PCA) is a discrete-interval order-matching mechanism used by NSE / BSE for thinly traded or heavily surveilled stocks. Instead of continuous matching during market hours, PCA matches orders at scheduled intervals (typically every 30 minutes or hour), allowing price discovery in a controlled environment.

How PCA works

In a normal session:

Continuous matching of buy and sell orders throughout 09:15 to 15:30.
Real-time price discovery.

In PCA:
