Since the implementation of the capital trading ban on Zijian Street, derivative trading activities on the Indian stock exchange have dropped by one third.

Exchange data on Thursday showed that since earlier this month when the Indian market regulator banned the US high frequency trading giant Jump Trading from entering the local market, the trading volume of Indian weekly stock index options has plummeted by one-third. The National Stock Exchange of India is the world's largest derivatives exchange by contract volume, and the turnover of index option premiums - a key indicator of actual capital input and risk appetite - has dropped by nearly 36% in the past two weeks. Thursday was the expiry date for the NSE's index options, with a premium turnover of 396.26 billion rupees. The Securities and Exchange Board of India issued a ban on Jump Trading on July 4, stating that an investigation found that the company was manipulating stock index through derivative positions.
