What is a limit order?

An order that only executes at your price or better, "buy YES, but only at 55% or less."

On order-book exchanges you can post a price and wait: if the market ever dips to your number, your order fills automatically, even while you sleep. It's how patient traders avoid slippage entirely, the market comes to them.

Foresee doesn't have limit orders yet (every trade fills instantly at the pool's price), but they're the natural power-user feature for markets like ours, and they're on the roadmap.
