The move comes in the backdrop of several complaints from various market participants regarding lack of transparency in arriving at the spot market prices, the regulator said.
The FMC said that transparent discovery of spot prices is a critical factor in smooth running of futures market as it is used as the reference price for settlement.
"The Commission has decided that to improve the transparency of spot price polling process, the spot price polling mechanism for every contract shall be displayed prominently by all the commodity exchanges on their websites," the Forward Markets Commission (FMC) said in a recent directive to MCX, NCDEX, NMCE and ACE.
The exhanges may assign a code for polling agents of a particular contract and reveal his location, basis centre and price for the day. A feedback window should also be provided for receiving complaints in this regard, which exchanges should address in a time-bound manner, it added.
The information should continue to be displayed even after the expiry of the contract for a period of three years, it added.
Exchanges have been using 'spot price polling mechanism' to arrive at the prevailing spot prices. This is currently being done by polling spot prices reported by spot price polling participants. Some exchanges undertake this activity themselves whereas some have outsourced this work to an external agency, it added.
