# Why are there restrictions on placing Nifty and Sensex option orders for certain strike prices?

> New Open Interest (OI) regulations will soon come into effect, imposing stricter limitations on the strike ranges available for Nifty and Sensex…

## Short answer

New Open Interest (OI) regulations will soon come into effect, imposing stricter limitations on the strike ranges available for Nifty and Sensex options. These changes are being implemented to comply with the exchange’s 15% OI cap per member.

To ensure continued access to all Nifty and Sensex option strike prices, iRage has partnered with Orbis Financial, a custodian and professional clearing member. Traders opting for migration to Orbis will not face the above restrictions.

Schedule a call-back to initiate the account opening with Orbis. It can take up to 10 working days for the custodian account to be set up.
