SHANGHAI, June 5 (Reuters) – The Shanghai and Shenzhen stock exchanges are considering suspending certain value-added market data feeds to institutions such as computer-driven quant funds, two sources said in an effort by Chinese regulators to tighten scrutiny of a sector blamed for contributing to market volatility.
The bourses may suspend providing granular transaction details including so-called tick-by-tick data, one of the sources said.
