Introduction
Fill-or-Kill (FOK) orders are a specialized trading tool designed for immediate execution or cancellation. This guide explores their mechanics, compares them to other order types, and provides actionable insights for traders.
Key Takeaways:
- Instant Execution: FOK orders require complete fulfillment within seconds or cancellation.
- Strategic Use: Ideal for trades requiring full position entry without price slippage.
- Risk Management: Avoids partial fills in volatile markets.
👉 Master advanced trading strategies to leverage FOK orders effectively.
What Is a Fill-or-Kill Order?
An FOK order mandates that a broker executes the entire order at the specified price immediately—or cancels it entirely. Unlike partial fills, FOK ensures an "all-or-nothing" outcome, making it valuable for:
- Price Stability: Prevents market impact by hiding unfilled demand.
- Illiquid Stocks: Less effective for low-volume securities due to execution challenges.
Example: A buy order for 10,000 shares at $5.20 either fills completely or cancels if only 5,000 shares are available.
