TRADING GLOSSARY
Post-only order
A post-only order is an instruction intended to add liquidity by resting in an order book rather than executing immediately against existing orders. If it would execute immediately, the venue rejects, cancels or adjusts it according to its rules.
EXAMPLE
In a hypothetical example, the lowest ask is $100. A post-only buy limit at $100 is rejected because it would immediately trade against that ask.
