What is the primary purpose of the stop trading mechanism in market operations?

• A. To speed up trading during high liquidity.
• B. To automatically execute all pending orders.
• C. To prevent trades when quotes are not available or market conditions are unsettled.
• D. To adjust the reference price.

Answer: (C)

Trading pauses are there to protect investors and keep price discovery orderly. When quotes aren’t available or market conditions are unsettled, continuing to trade can lead to trades at prices that don’t reflect current information. The stop trading mechanism halts activity to give time for reliable quotes to return and for information to be absorbed, so trading resumes only when it’s fair to do so. It isn’t about speeding up trading during high liquidity, nor does it automatically execute pending orders, and it isn’t about changing the reference price.
