According to sources, trading in debt platform would begin from next month, while that SME segment would be launched after receving Sebi's final approval.
The bigger rivals--BSE Ltd and National Stock Exchange (NSE) are already running SME platforms, while NSE has recently launched a separate unified debt segment. BSE is awaiting the approval of Securities and Exchange Board of India (Sebi) for debt platform.
Besides, the bourse said it has received an "in-principle" approval from Sebi for operationalising the SME platform, which would offers small and medium companies to raise funds from the primary market.
The volumes on MCX-SX, which began trading in February, have been improving in the past few days, it said.
