Which protection mechanisms must be taken into account during volatility interruptions?

The correct choice encompasses a comprehensive understanding of the various protection mechanisms that are essential during volatility interruptions.

Static Vol Interruption refers to a predetermined threshold that, when reached, temporarily halts trading to prevent excessive volatility. It is important because it allows market participants to reassess conditions without the pressure of active trading, effectively shielding them from significant price swings that could impact their positions.

Dynamic Vol Interruption, on the other hand, adjusts its thresholds based on current market conditions. This mechanism offers flexibility, allowing for responsiveness to changing volatility levels in real-time, which is vital during extreme market events.

Lastly, the Market order matching range is crucial as it sets the parameters within which market orders can be executed during periods of abnormal volatility. This ensures that orders are filled at reasonable prices, helping to maintain market integrity.

Together, these protection mechanisms create a robust safety net designed to manage the risks associated with sudden price fluctuations in the marketplace, thereby promoting orderly trading and reducing the likelihood of severe market disruptions.
