This is pursuant to the Exchange circular no. 20231027-46, dated October 27, 2023, regarding Advisory on the market order feature, and exchange circular number 20231220-28, dated December 20th 2023 regarding Pre-Trade Risk Control - Enhancements to Market price order in Equity Derivatives segment, with a view to further strengthen the pre-trade risk control measures to ensure orderly trading and effective risk management, it has been decided to implement certain changes to the market price order feature.
Trading members are hereby requested to note the following enhancements which shall be implemented for market price orders (day as well as IOC orders) –
1. Market price orders shall be rejected in a contract which has not traded for the day, i.e. LTP has not been discovered in that contract.
For contracts where LTP for that day has been discovered,
2. Market price orders shall be allowed to be traded only up to a price range based on pre-defined market price impact (MPI) percentage of the last trade price (LTP) of that contract.
- For buy orders, it shall be up to X% higher than LTP.
- For sell orders, it shall be up to X% lower than LTP.
3. This price range of X% higher/ lower than LTP, shall also be subject to minimum absolute value in rupee terms.
4. Further, members/traders can define MPI% for every market price order, such that 0% =< trader-defined MPI% =< X%.
- Amongst the trader-defined MPI% and Exchange-defined MPI%, lower MPI% shall be considered during order matching, irrespective of minimum absolute value.
- However, if trader has not defined MPI% with the market price order, then Exchange-defined MPI% shall be applicable for such orders, subject to minimum absolute value.
5. If price of opposite side orders is beyond the MPI price range, then the entire incoming market price order (or remaining order quantity if it is partially executed) shall be cancelled.
6. If there are no opposite side orders, then the entire incoming market price order (or remaining order quantity if it is partially executed) shall be converted to a passive limit price order at the best price on same side of the order book, based on price-time priority.
7. If there are no pending orders on either side of the order book, then the entire incoming market price order (or remaining order quantity if it is partially executed) shall be converted to a passive limit price order at the day’s LTP of that contract.
8. The above-mentioned MPI range validation shall also be applicable for order modification requests i.e., pending limit price order being modified to a market price order.
9. Multi-legged orders with ‘market price’ condition for all contracts shall not be allowed. However, multi-legged orders with ‘limit price’ condition shall continue to be available.
The parameters to arrive at the MPI range for market price orders shall be set as follows –
