What happens to existing orders during a trading suspension?

During a trading suspension, existing orders and quotes are typically deleted. This approach ensures that the market operates with up-to-date and relevant information when trading resumes. When trading resumes after a suspension, it is crucial that all participants have the same opportunity to enter new orders based on the current market conditions, avoiding any scenarios where outdated orders could disrupt the new trading phase.

Keeping orders unchanged could lead to confusion and inefficiencies, while automatically transitioning them into the next trading phase could cause issues if those orders are no longer valid due to market changes. The cancellation of all existing orders and quotes is a standard practice to reset the market environment and ensure fairness among all traders.
