IV surge (fixed 5 %) report
The fixed-threshold twin of IV surge: liquid contracts whose IV moved at least 5 % (relative) against the previous session close.
Overview
The IV surge (calendar, fixed 5 %) report is the original "Cal" IV surge page: identical to IV surge with the threshold locked at 5 % and no inputs.
The data delay depends on your plan and is shown on every view: the as-of time and the delayed label sit above the results. On the Free plan reports show the previous session.
How the report is built
- Baseline = previous session close IV.
- Liquid contracts only; IV Δ % >= +5 % or <= -5 %.
- Sorted by IV Δ %.
Before you start
Any signed-in plan can open the report from Research → Reports. Your plan decides how fresh the data is and how much history you can read. CSV export of this report is open to every plan.
Steps
- Open Research → Reports, choose the Implied Volatility family (or type "IV surge (calendar, fixed 5 %)" in Search reports) and open IV surge (calendar, fixed 5 %).

- Change any filter (for example pick one symbol) and press Run to refresh the grid.
- Choose Save as screen to keep your variant under Research → Saved Screens, where you can schedule it or turn it into an alert.

| Prev IV | Implied volatility at the close of the previous trading session (the baseline). |
| IV change (points) | IV minus previous IV, in volatility points (0.05 = 5 points). |
| IV Δ % | Relative IV move: (IV - previous IV) / previous IV. |
| IV surge ratio | IV / previous IV. 1.10 means IV is 10 % higher. |
| IV at session open | The first IV recorded this session. |
| IV session high | The highest IV recorded this session. |
| IV session low | The lowest IV recorded this session. |
| Volume | Contracts traded so far this session (cumulative, as of the snapshot time). |
| OI | Open contracts as of the prior settlement. |
| Bid | Best bid of the latest snapshot. |
| Mark | Bid/ask midpoint, per share. This is the premium the reports use. |
| Premium | Mark x 100: the price of one standard contract in USD. |

| Und. Price | The latest price of the underlying stock. |
| Delta | How much the option price moves for a $1 move in the stock (calls 0 to 1, puts 0 to -1). |
| Gamma | How fast delta changes for a $1 move in the stock. |
| Theta | Time decay per calendar day, per share. Negative for a long option. |
| Vega | Price change for a 1-point change in implied volatility. |

Percentages are stored as fractions and displayed as percentages (0.05 is shown as 5 %). An unknown value shows as "-", never as 0.
How to read it
- A 5 % relative move is small (IV 30 % to 31.5 %), so the list is long. Use IV surge (absolute points) for bigger moves.
Example
Illustrative only - the symbol and numbers are invented.
XYZ 95 put: Prev IV 40 %, IV 43 %, IV Δ % +7.5 %. It qualifies because 7.5 % is above 5 %.
Using it in your research
- Use as a quick daily overview, then narrow down in IV surge.
Treat every row as a starting point for your own research, not as a signal. Volume and open interest never say whether a trade was a buy or a sell.
Troubleshooting
A surge report is empty
A surge compares today with the previous trading session close. On the first session after a holiday, or for contracts that are new, there is no baseline, so the contract is left out. Lower the threshold or widen the date range.
The report shows "No Records Found"
The filters may be too narrow for the session, or the session has only just opened. Widen a threshold, clear the symbol, or check the as-of time to see which session you are reading. On the Free plan you read the previous session.
