This is in partial modification to the Exchange circular no. 20240205-29, dated February 05, 2024 regarding Pre-Trade Risk Control - Enhancements to Market price order in Equity Derivatives segment. This is also further to Exchange circular no. 20240405-40, dated April 05, 2024 regarding Pre-Trade Risk Control – Limit Price Protection for limit price orders in Equity Derivatives segment.

Trading members are requested to note the following additional enhancements to market price orders to further strengthen the pre-trade risk management mechanism –

Market price orders shall also be validated against the prevailing LPP (limit price protection) range for the respective contracts, in addition to the existing validation of applicable MPI (market price impact) range. In other words, market price orders shall be allowed to be traded up to a price range which shall be determined based on the following –

  • Buy orders shall be allowed to be traded up to a minimum of higher MPI and higher LPP limit values
  • Sell orders shall be allowed to be traded up to a maximum of lower MPI and lower LPP limit values

All other provisions mentioned in the above-mentioned circulars shall remain unchanged. Trading members are requested to refer to the illustration given below for revised mechanism. 

Further, the above-mentioned enhancements have been made available in the simulation environment of Equity Derivatives segment. Trading members are requested to test the same.

Based on the usage of these enhancements and further inputs from market participants, the Exchange may review these measures periodically and implement further improvements/changes as necessary. Members are also advised to exercise due care and caution while placing orders by reviewing and setting limits as advised in our earlier circulars.
