Contingent Order

A contingent order is an instruction to your broker to buy or sell something only after a specific condition elsewhere in the market is met. Instead of just saying "sell this now," you say "sell this, but only if that other thing happens first." Until the condition is met, the order sits inactive; once it's met, the order becomes "live" and is sent to the market to be filled at whatever terms you specified.

The condition, or "trigger," is usually the price of a related instrument. A common example in options trading is placing an order to sell a call option, but only if the underlying stock trades at or below a certain price. The two parts of the order are linked: the trigger event (stock price) and the action (sell the option at a given price or better). Some brokers also let you build contingent orders across unrelated instruments, or chain multiple orders together so that filling one automatically cancels or activates another.

The nuance that trips people up is that a contingent order is not a guarantee of price or even of execution. Once the trigger fires, the order usually becomes a regular market or limit order, which means it is still subject to normal execution risk: the market can move between the moment the trigger fires and the moment your order actually fills, especially in fast or thin markets. A contingent order also depends entirely on your broker's system correctly monitoring the trigger; if the platform has a delay or the contingency is based on a price feed that gaps, the order may trigger later or earlier than you expected.

Contingent orders are also not standardized across brokers. Some platforms offer rich contingency logic (multiple conditions, OCO/OTO style links, cross-asset triggers), while others only support simple single-condition versions, or none at all, requiring you to build the logic yourself with alerts and manual entry.
