Maker and Taker: A maker adds an order to the book that waits to be filled; a taker fills an order that's already there. Exchanges often charge them differently.

What it means

A maker adds an order to the book that waits to be filled; a taker fills an order that's already there. Exchanges often charge them differently.

Example

Placing a limit buy at 40¢ below the current ask makes you a maker. Hitting the 42¢ ask immediately makes you a taker.

Practical tip

Check Kalshi's current fee schedule: taker fees are usually higher, so patient limit orders can be cheaper.
