Your trade was placed during a trading halt known as a Circuit Breaker. Circuit breakers are thresholds where market-wide trading halts are instituted. No security transactions (e.g. pending trades) will be executed during trading halts. The below trading halts will be implemented by markets if a single day decline in the S&P 500 Index exceeds the below levels:
Level 1 – Decline of 7% will result in a 15-minute trading halt
Level 2 – Decline of 13% will result in a second 15-minute trading halt
Level 3 – Decline of 20% will result in the market closing for the remainder of the day
Additionally, volatility in a specific security (e.g. stock) may result in a trading halt for that specific security. These can be implemented by trading exchanges regardless of whether a market-wide halt is instituted.
Note that the price of securities can fluctuate between the start of a trading halt and the execution of a security after the trading halt. Cryptocurrency transactions are not impacted by stock market circuit breakers and trading halts.
