Question 1

What is IV Rank?

Accepted Answer

IV Rank measures where the current implied volatility sits relative to its range over the past year. A rank of 80% means IV is in the top 20% of its annual range — ideal for selling premium.

Question 2

What's the difference between IV Rank and IV Percentile?

Accepted Answer

IV Rank compares the current IV to the high and low over the past year (linear scale). IV Percentile counts the percentage of days IV was lower than today. IV Rank is better for spotting extremes; IV Percentile is better for gauging how unusual current levels are.

Question 3

How do I use the scanner?

Accepted Answer

The scanner page shows all tracked stocks ranked by IV rank. You can sort by any column, filter by sector, and search for specific symbols. High IV Rank stocks (80+) are great candidates for premium-selling strategies.

Question 4

Where does the data come from?

Accepted Answer

We pull options data from major exchanges via institutional-grade data feeds, with quotes updated throughout the trading day.

Question 5

What plans do you offer?

Accepted Answer

We have three plans: Free ($0 — full IV scanner, sector heatmap, 10 watchlist symbols, 500 API calls/month), Pro ($49/mo or $470/yr — flow alerts, earnings analysis, short pressure scanner, GEX/DEX, CSV export, API access, 50 watchlist symbols), and Premium ($149/mo or $1,430/yr — everything in Pro plus live streaming, custom alert rules, dark pool flow, unlimited watchlist, bulk API).

Question 6

How does billing work?

Accepted Answer

We offer monthly and yearly billing via Stripe. Yearly plans save you roughly two months. You can upgrade, downgrade, or cancel at any time from your billing settings. No long-term contracts.

Question 7

Can I cancel anytime?

Accepted Answer

Yes. Cancel from Dashboard > Settings > Billing. You keep access through the end of your current billing period. No cancellation fees.

Question 8

Do you offer refunds?

Accepted Answer

We don't offer automatic refunds, but if you're unhappy within the first 7 days, email support@voledge.io and we'll work it out.

Question 9

What is unusual options flow?

Accepted Answer

Unusual flow flags options orders where volume significantly exceeds open interest, or where the trade size is abnormally large. These can signal institutional or 'smart money' positioning. Available on the Flow page for Pro and Premium users.

Question 10

How do I export data as CSV?

Accepted Answer

On the Scanner or Flow page, click the 'Export CSV' button in the top-right toolbar. This downloads the current filtered view. CSV export requires a Pro or Premium plan.

Question 11

Can I set custom alerts?

Accepted Answer

Pro users can set IV rank threshold alerts on watchlist symbols. Premium users get a full rule builder with multi-condition alerts (e.g., IV Rank > 80 AND volume > 10,000). Manage alerts from the Watchlist page.

Question 12

Is there an API?

Accepted Answer

Yes! Pro and Premium plans include API access for programmatic data retrieval. Create an API key in Dashboard > Settings > API Keys. See our docs for endpoints, rate limits, and examples.

Question 13

What is the earnings IV crush analysis?

Accepted Answer

The Earnings page shows upcoming earnings with current IV, estimated move, and historical IV crush data. IV crush is the sharp drop in implied volatility after an earnings announcement — knowing the typical crush helps you size trades correctly.

Question 14

How does the Short Pressure Scanner work?

Accepted Answer

We estimate daily short interest by combining FINRA short volume reports, bi-monthly FINRA SI snapshots, and SEC Fails-to-Deliver data. A calibrated cover rate model interpolates between official reports to give you a daily estimate. The composite Short Pressure Score (0-100) weights SI%, short volume ratio, days to cover, FTD momentum, and put flow bias. Stocks scoring 80+ with SI above 15% are flagged as squeeze candidates.

Question 15

How often is data updated?

Accepted Answer

Scanner data refreshes every 5 minutes during market hours. Options flow updates every 3 minutes. Premium users with live streaming get updates every 15 seconds.

Question 16

Which browsers are supported?

Accepted Answer

VolEdge works in all modern browsers: Chrome, Firefox, Safari, and Edge. We recommend Chrome or Firefox for the best experience. Mobile browsers are fully supported.
