The Multi-Commodity Exchange of India Limited (MCX), on June 25, 2026, issued a circular informing members about the movement of select products between system partitions to optimise system performance and efficiently manage data streams. The change is intended to improve the Exchange's system operations without impacting the existing API framework.
As part of this migration, Good Till Cancelled (GTC) and Good Till Date (GTD) orders for the product symbols OFNATURALGAS and OFGOLDM will be cancelled at the end of the trading day on June 26, 2026. Members have been advised to make the necessary changes at their end. The revised product movement details will be reflected in the product master file (Mcxscrip.bcp) in accordance with MCX Reference Data Files (Masters) Version 1.2.
The revised partition mapping will become effective from June 29, 2026. Updated stream details will be available in the Stream Master hosted on the Exchange's SFTP server under the prescribed contract master path. MCX has clarified that there will be no changes to the Market Data Interface (MDI) and Exchange Trading Interface (ETI) APIs.
