The Securities and Exchange Board of India (SEBI) ordered the National Stock Exchange of India (NSE) to pay a fine of about ₹1,000 crore within 45 days for its supervisory laxity.
Under NSE co-location facility, brokers can place their servers in the exchange’s data centre.
But some brokers were given preferential access to the exchange servers.
They gained thousands of crores because of this unfair advantage.
