Under the futures and options (F&O) segment, two stocks were banned from trade on Thursday, October 26, by the National Stock Exchange (NSE). The securities banned for the F&O trade are RBL Bank and Delta Corp Ltd.  

Derivative contracts of these stocks were banned as the open market interest for these securities has crossed 95% of the market-wide position limit (MWPL) set by the exchanges. The MWPL is the maximum number of contracts that can be opened at any particular time. 

The open interest for the derivative contracts of RBL Bank stood at 86% of its MWPL at the closing time on Wednesday. The above security was retained on the list from October 25. 

Delta Corp saw the open interest for its F&O contracts touch 96.5% of its MWPL on Wednesday. The above security was added to the list for Thursday, October 26. 

The ban will be lifted once the position falls below 80%. Traders will get penalised for buying or selling these securities. They will be available for trading in the cash market.

The National Stock Exchange updates the list of securities on the F&O ban list daily. This list serves as a guide for traders and investors in the market. Traders who trade in indices do not encounter a situation of security ban.
