Market Wide Position Limits

At the end of each day the Exchange disseminates the aggregate open interest across all Exchanges in the futures and options on individual scrips along with the market wide position limit for that scrip and tests whether the aggregate open interest for any scrip exceeds 95% of the market wide position limit for that scrip. If yes, the Exchange takes note of open positions of all client/ TMs as at the end of that day in that scrip, and from next day onwards the client/ TMs should trade only to decrease their positions through offsetting positions till the normal trading in the scrip is resumed.

The normal trading in the scrip is resumed only after the aggregate open interest across Exchanges comes down to 80% or below of the market wide position limit.
A facility is available on the trading system to display an alert once the open interest on the NSE in the futures and options contract in a security exceeds 60% of the market wide position limit specified for such security. Such alerts are presently displayed at time intervals of 10 minutes.
