Params for volatility interruptions are set in a way that they only occur in extreme market situations.

The statement is accurate; volatility interruptions are indeed designed to activate only in extreme market situations. This mechanism helps to maintain market integrity and prevents excessive price movements that might occur during periods of high volatility or panic trading. By establishing parameters that trigger these interruptions only under severe conditions, market participants can have a moment to assess the situation and make more informed decisions. This system aims to reduce the risk of market manipulation and ensure that trading remains orderly, thereby fostering longer-term confidence in the trading venue.

In normal market conditions, these interruptions would not trigger, allowing trading to proceed smoothly without unnecessary pauses. Such a provision is key for safeguarding the trading environment, especially in highly volatile markets.
