What are Open Interest Limits?

Along with abiding to the initial margin requirement mandated by the exchange, brokers are also subject to position limits. Open Interest (OI) is a figure that informs you how many futures or options contracts are outstanding (open) in the market currently. For customers, there is an OI limitation of 5% of the total number of all derivative contracts for the same underlying and a 15% OI restraint for brokers.
