| Number of partitions to be reduced from 8 to 4 in equity and equity derivatives segment |
Currently, there are 8 partitions in equity and equity derivatives segment. Each partition is serving a set of products. It is proposed to reduce the number of partition from 8 to 4 effective from February 11,2019. This would mean that post February 11,2019 trading will happen in only 4 partitions for all the products.
The partition information is also provided in equity segment’s scrip master file (SCRIP_DDMMYYY.txt) under the column 5 (Partition ID and Product ID). Similarly, the same information is provided in equity derivatives master file (EQD_CODDMMYY.csv) under column 13(Partition ID).
Impact on ETI based applications
All ETI applications which are making use of partition ID for retransmission of orders, trades and other messages which are partition oriented will have to make necessary changes to query for 4 partitions only.
The number of partition information is also part of Session logon response (Template ID 10001) message of ETI API.
Impact on IML based applications
All IML based applications which are making use of partition ID in their applications, for query such as incremental trade query (1085), trade enhancement request (1080) etc. will have to make necessary changes to query for 4 partitions only. The number of partition information is also part of User logon reply message (1131) of IML API.
Also, kindly note that before reducing the number of partition to 4, the Exchange would move the products from those partitions to other partitions. certain products will move from one partition to another over next few days. The change of partition will be updated in the scrip_DDMMYY.txt file and EQD_CODDMMYY.csv whenever a product is moved from one partition to another.
Impact on EMDI/ EOBI
The movement of product will not have impact on the existing EOBI/EMDI stream. The products that are part of one stream today will continue to be part of same stream. However, unlike earlier where one stream had products of one partition only, the stream may now have products belonging to different partitions as well.
