# Binary Market Best Practices

> How to write clear, resolvable YES/NO markets.

## Ideal binary market example

> **Question:** Will the U.S. enter a recession in 2025?
>
> **Resolution Date:** December 31, 2025, 11:59 PM
>
> **Resolution Rules:** This market resolves **YES** if the National Bureau
> of Economic Research (NBER) announces a U.S. recession at any point in 2025
> (announcement must occur by Dec 31, 2025), or if the Bureau of Economic
> Analysis (BEA) reports two consecutive quarters with negative real GDP
> growth between Q4 2024 and Q4 2025 (inclusive). If neither condition is
> met, this market resolves **NO**. Advance estimates count toward
> resolution.
>
> **Sources:**
>
> * [NBER official announcements](https://www.nber.org/)
> * [BEA GDP data](https://www.bea.gov/data/gdp/gross-domestic-product)

## Crafting great binary markets

### Ask a simple, direct question

* Phrase clearly as a Yes/No question.
* Include the event, indicator, and timeframe.
* Avoid vague words like "soon," "likely," or "possible."

### Provide precise resolution rules

* Clearly define conditions for **YES** and **NO** outcomes.
* Use objective, measurable criteria.

### Set a clear resolution date

* Choose a date clearly **after** the expected resolution event.
* Resolution dates should not exceed one year from proposal.

### List reliable sources separately

* Provide official, direct links separately from rules.
* Prefer governmental or authoritative institutions.
* Users depend on these to verify outcomes.

### Use a relevant market image

* A great image improves engagement.
* Choose topic-related, publicly hosted images ≤ 500 KB.
