How to Buy Bank Nifty options on Zerodha

You cannot trade in all the Nifty and Bank Nifty options on Zerodha because of the Open interest limitation of this broker.

The position limit of Zerodha is set by the exchange of a trading member or broker. In the bank nifty and nifty index, options contracts are limited to 500 crores or 15% of the total open interest market. However, since Zerodha has many clients actively trading in index options, the position limit is usually met.

Due to the above limitation, the allowed trading range is restricted to keep the OI utilization within sanctioned limits. However, Zerodha has tied up with - Orbis Financial to curb the limitation and to enable trades in all Nifty and Bank Nifty options contracts for their clients.

To start trading in all the Bank Nifty and Nifty options, you will have to open a custodian account with Orbis, but you need not worry about the change in the platform, as you will continue to trade with Zerodha using Kite.

MIS stands for Margin Intraday Square Off and is useful for traders doing intraday trading in Options. Intraday trading means to buy and sell the order on the same day. The trade is completed on that day. Nothing is carried off to the next day. Zerodha offers margin leverage for intraday traders. There is no margin provided for traders buying options as there is no margin requirement for such a trade. However, the seller of options is required to maintain a margin. When you use an MIS code, you only need to maintain 50% of the margin. So, entering this code gives 50% margin leverage to Option sellers and allows them to make more trade with the same amount of money.
