Market age: Established markets typically have better liquidity.Related: Polymarket Correlation Analysis: Understanding Market Relationships
Resolution Criteria Clarity
Clear resolution prevents disputes:
Specific conditions: Markets should have unambiguous resolution criteria. Objective sources: Resolution should depend on verifiable information. Avoid ambiguity: Steer clear of markets with vague or subjective criteria. Check resolution method: Understand how disputes are handled. Historical precedent: Markets similar to past ones are often clearer.Finding Your Edge
