Example - How to Use Option Volume
Option Volume helps you understand which side of the options market is more active at any given time. Here are some practical ways to use it:
Reading the Bars
Green bars = Call volume
Purple bars = Put volume
The taller the bar, the more activity on that side
Practical Uses
Identifying directional bias - When call volume is consistently higher than put volume throughout the session, it suggests more bullish activity in the options market. When put volume dominates, it suggests more bearish activity
Spotting volume spikes - A sudden spike in call or put volume can signal that large participants are entering positions. When this happens near a key GEX level it adds confluence to that level
Comparing call vs put activity - Use the stacked bar view to quickly see at a glance which side is dominating. A balanced view suggests the market is in a neutral state. A clear dominance of one side suggests directional pressure
Filtering by expiration - Use the 0 DTE filter to focus only on same day options activity which has the most immediate impact on price movement

Note: Option Volume gives you a broad view of market participation. Always combine it with your GEX levels, footprint and DOM for a complete picture before making any trading decisions.
