There are no maximum and minimum price ranges for Futures and Options Contracts. However, to avoid erroneous order entry, dummy price bands have been introduced in the Derivatives Segment. Further, no price bands are prescribed in the Cash Segment for stocks on which Futures & Options contracts are available for trading. Also, for those stocks which do not have Futures & Options Contracts available on them but are forming part of the index on which Futures & Options contracts are available, no price bands are attracted provided the daily average trading on such indices in the F & O Segment is not less than 20 contracts and traded on not less than 10 days in the preceding month.
