Post-Only Orders

Post-Only orders are a specific type of limit order used on Delta. These orders are only accepted if they don't immediately match with an existing order already on the order book. In essence, a Post-Only order is one that is "posted" in the order book and doesn't get executed right after it's submitted. The key benefit of Post-Only orders is that they contribute liquidity to the order book, rather than taking it away. This means that when traders submit Post-Only orders, they are eligible for the maker fee rather than the taker fee. To activate Post-Only mode, simply select the "Post Only" option in the order form before submitting your order.
