Daily movement is bounded
For standard Korean equities, the daily upper and lower limits are generally 30% from the previous close. A stock at its limit may still be difficult to trade if orders are one-sided.
Interruptions are not the same as the daily limit
Volatility interruption mechanisms can pause continuous trading and move a security into a call auction.
- A displayed price is not a promise of execution.
- Limit-up and limit-down queues can be extremely unbalanced.
- Corporate actions and special trading arrangements can affect reference prices.
