The move is part of NSE's effort to improve the liquidity in the equity options segment.
The exchange had in June revised the transaction charges in the equity options segment for a period of three months from July 1 to September 30.
In equity options, the bourse had given a flat concession of 40 per cent on the transaction charges levied on the incremental billable volume, or premium value, above Rs 1,500 crore in a month for three months ending September 30.
"Based on the positive market feedback, it has been decided to extend the same for a further period of three months from October 1, 2016 to December 31, 2016," NSE said in a circular.
