The Hong Kong exchange has proposed installing new trading controls that would help to modernise its outdated market structure and bolster Hong Kong’s competiveness as a global financial market.

The Hong Kong Exchanges and Clearing on Friday published a consultation on reintroducing a closing auction and installing new volatility controls. The consultation will last 12 weeks and will close on April 10, the HKEx said in a statement.

“As an international exchange, we have to stay alert for changes that may require new mechanisms to protect market integrity,’’ Roger Lee, HKEx’s head of market operations, said in a statement.

“Our proposed ... enhancements are designed to offer greater safeguards to our market and improve market efficiency.’’
