What is a mistrade?

What is a mistrade?

• A. An on-exchange, on-order-book trade that can be refused if price of trade deviates considerably from market price or orderly and fair market conditions are not ensured.
• B. An off-exchange trade settled after hours.
• C. A trade executed regardless of price conditions.
• D. A trade that never gets cancelled.

Answer: (A)

A mistrade is an on-exchange trade that takes place in the official order book but can be refused or cancelled because it violates market rules. If the execution price is far out of line with the current market price or if allowing the trade would undermine an orderly and fair market, the exchange may reject the trade. The key idea is that it happens within the exchange’s trading system and can be reversed to protect price integrity and fairness. Why the other ideas don’t fit: an off-exchange trade isn’t on the official order book, so it isn’t a mistrade; a trade executed regardless of price conditions ignores the market’s price discipline rather than being rejected for violating it; and a trade that never gets cancelled would not reflect the concept of a potentially reversed transaction due to rule violations.
