Contract Volume
Displays the raw number of Call vs Put contracts traded. Provides a high-level view of general market interest.
Premium Flow (Capital)
Shows the actual dollar amount ($) spent. A small volume of highly expensive contracts can outweigh a large volume of cheap ones, revealing where true institutional capital is deployed.
Aggression & Direction (Execution Side)
Trades filled on the Ask represent aggressive buying (Call buying = Bullish, Put buying = Bearish). Trades filled on the Bid often represent yield generation or shorting (Call selling = Bearish, Put selling = Bullish).
DTE Timeframes
Groups flow into days to expiration. Weeklies indicate short-term speculation or hedging, while Leaps indicate long-term macroeconomic positioning.
Unusual Activity (Volume vs OI Ratio)
Highlights specific strikes where today's trading Volume significantly exceeded the existing Open Interest. Values > 1.0 strongly suggest new positions being opened rather than old positions being closed.
Expiry Distribution
Shows exactly which expiration dates are attracting the most contract volume. Uses a logarithmic scale to ensure outliers don't drown out smaller dates.
Strike Distribution
A precise breakdown of where Call and Put volume is clustered across all strike prices.
