What Is an Order Book? Reading Market Depth | HiYesNo Academy

Updated: 2026-07-02 · Author: HiYesNo Content Team · Type: Academy article

An order book shows buy and sell orders waiting to be matched in a market. It helps users see how much depth exists around different YES/NO prices.

On HiYesNo, read the order book together with last price, spread, and available size. It reflects participant interest, not a guaranteed outcome.

Key Points

  • Read the market question and rules first.
  • Then review price, liquidity, and order information.
  • Understand risk and do not treat price as a guarantee.
