Detailed Explanation
Why It Matters:
Guarantees maker fees (often lower or rebates) instead of taker fees; ideal for cost optimization and providing liquidity without accidental aggressive fills.
How It Works:
When placing a limit order, enable "Post-Only." If the price would cross the book immediately, the order is rejected instead of executing as taker.
Common Mistakes:
Forgetting to enable it and paying higher taker fees; placing too aggressively and getting rejected repeatedly.
