What Pulse answers
Open Pulse. Pulse looks at one universe, such as a watchlist, and asks:
- Which names have unusual options activity today?
- Is the activity one-sided toward calls or puts?
- Does price agree with that pressure?
Click any symbol to follow it in every panel. Double-click it to open the symbol elsewhere.

The Flow loaded chip shows the time of the current snapshot.
Volume is the volume for today's trading session across all expirations within the selected scope. Pressure counts contracts traded; it does not show whether they were bought or sold.
Universe flow breadth
The strip across the top summarizes the whole universe:
| Tile | What it shows |
|---|---|
| Coverage | How many names have data |
| Pressure · by names | How many names lean call versus put, each counted once |
| Pressure · by volume | The same balance weighted by each name's options volume |
| Activity vs 5-day norm | How many names trade above 1x, one pip each, and the median |
| Volume concentration | The share of volume in the top five names |
By names and by volume can disagree. A few heavy names can lean one way while most names lean the other.
Activity & pressure
One row per symbol, ranked by your Rank flow by choice:
- Activity: today's options volume versus its 5-day norm, on a log scale from 0.25x to 16x. 1x is a normal day.
- Pressure: puts to the left, calls to the right, as a multiple of the normal call-versus-put gap.
- ! marks pressure that disagrees with price, for example call pressure while price is down.
| Rank flow by | Ranks first |
|---|---|
| Activity | The busiest names versus their norm |
| Pressure | The most one-sided names, calls or puts |
| Divergence | Names where pressure and price disagree, then the most active and one-sided |
Intraday flow
The followed symbol's session in 5-minute buckets from 9:30 to 4:00 ET. Columns are pressure at that time, calls above zero and puts below. The line is activity. Both are multiples of their 5-day norm on one scale, with dashed ±1x guides.
Flow map
Every covered name at its true position. Right of the dashed line is above the 5-day norm; above zero is call pressure and below is put pressure. Bigger dots trade more options. Show Top 8 labels or All labels.
Today's range
Each bar runs from the day's low to its high, as percent from the prior close. The wider marker is the current change. Choose Range or Change (change only), and sort by Near High, Near Low, Widest, %Chg or Top Cap.
The header counts names up, flat and down, and the average range width.
A quick scan
- Rank by Activity and note the names well above 1x.
- Switch to Pressure to see which of them are one-sided.
- Switch to Divergence to find pressure that disagrees with price.
- Click a name to follow its intraday flow and range.
- Double-click to open it in Activity or another workspace.
Unusual activity and pressure are context for where to look. They do not predict direction.
