In the event of trading suspension, which positions remain unaffected?

The correct answer highlights that in the event of a trading suspension, all open positions remain unaffected. Open positions are those trades that have already been executed, meaning the buyer and seller have entered into a legally binding agreement. During a trading suspension, while the market may halt further trading activities, the rights and obligations associated with these open positions continue to exist without interruption.

This is important as it ensures that traders can still manage their existing positions, including any margin requirements or risk assessments, even while the market is not actively trading. Therefore, all open positions maintained by traders are considered unaffected during a trading suspension, enabling traders to plan their next steps once trading resumes.

On the other hand, inactive positions typically refer to those that have not been recently traded or are dormant, and they could be more temporary in nature. Upcoming orders and pending modifications, which are related to future trading activities rather than current positions, become irrelevant during a suspension because no new trades or changes to existing orders can occur until trading is resumed.
