Limit Orders

A Limit Order allows you to set the maximum price you are willing to pay when buying, or the minimum price you are willing to accept when selling.

When to Use?

• When you want to control the exact entry or exit price.

• Suitable for patient traders waiting for favorable market conditions.

Key Points

Execution is not guaranteed — the order will only be filled if the market reaches or exceeds your set price.

Why Did My Limit Order End Up Being Executed as a Market Order?

• The logic of a limit order is:

  • A buy order will be executed at a price ≤ your set price.

  • A sell order will be executed at a price ≥ your set price.

• If you do not enable the Post Only option, the system will match your order against existing orders in the order book immediately, as long as the price condition is satisfied.

• To ensure your order is always placed into the order book as a Maker order, you need to check Post Only. Otherwise, your order may be executed immediately as a Taker order.

Example:

• You set a buy limit order for BTC/USD at 30,000.

• The current best ask price is 29,900.

• Result: The system will execute the order immediately at 29,900 instead of placing it at 30,000 to wait.
