Fixed Income Market Making (FIMM) is a platform that allows debt markets participants to trade NSE listed debt instrument issued by the Federal Government, State Governments or Corporations on a transparent order book with firm orders. The objective of FIMM is to provide liquidity and transparency through an order book with firm orders, pre and post-trade reporting, clearing and settlement solutions.

There are two types of market making:​
  • Quote-driven market making - only the bids and asks of market makers are displayed in the market. The orders of regular broker-dealers are not displayed.
  • Order-driven market making - all the orders of buyers and sellers are displayed in the market, showing the quantity and the price at which a buyer/seller is willing to trade.
