Cheddar Flow combines options order flow, unusual activity and dark-pool data for users researching US equity options.
About
Cheddar Flow presents unusual options activity and sweep orders spanning exchanges, with filters for narrowing the flow. Contract details include bid and ask prices, volume, implied volatility and open interest.
The platform also describes dark-pool data, gamma exposure by strike and expiration, and Power Alerts. Interpret transactions alongside expiration and position context: a large order alone does not reveal the complete trade intent.
