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.

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

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.

How do I use the scanner?

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.

Where does the data come from?

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

What plans do you offer?

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).

How does billing work?

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.

Can I cancel anytime?

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

Do you offer refunds?

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.

What is unusual options flow?

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.

How do I export data as CSV?

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.

Can I set custom alerts?

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.

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.

What is the earnings IV crush analysis?

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.

How does the Short Pressure Scanner work?

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.

How often is data updated?

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.

Which browsers are supported?

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.

# High IV Rank Stocks Today: ARM Hits 81 as Chip Names Rally on Single-Day Vol

**ARM** leads the high IV rank stocks today list at 81, with **RBLX** close behind at 80 — both names sitting at 100th-percentile current IV (102.4% and 103.8%). Tech rallied 3.1% on a session that saw **AMD** +14.2%, **ARM** +14.7%, and **QCOM** +11.3% absorb sharp single-day moves, while breadth ran negative underneath: 7 advancing, 15 declining, 3 unchanged.

## Market Volatility Regime: VIX and Term Structure

VIX and term structure data are not in today's snapshot, so the regime read comes from GEX and IV dispersion. Aggregate GEX is deeply positive across the indices — SPY at +596.2B, QQQ at +230.3B — with call wall and max gamma stacked at the same strikes (SPY 714, QQQ 664). That's a pinned, mean-reverting backdrop at the index level. The IV picture underneath is bifurcated: average IV rank is 49, but 11 names sit at or above 50 with several pegged at 100th-percentile current IV. Dispersion is concentrated in growth tech and consumer names rather than the indices themselves.

## Top IV Rank Setups Today

**ARM** ran +14.7% but held a 100th-percentile current IV at 102.4% — the surface did not fully crush. That suggests unresolved positioning or follow-through event risk. A directional move that doesn't relieve IV is the trickiest premium-selling profile, since rank is rich but realized may stay elevated.

**RBLX** at 80 IV Rank, 103.8% current IV, with a quiet 1.0% session on 8K volume. Elevated implied volatility rank against muted price action is a cleaner premium-selling profile than ARM's — assuming no event is pulling the surface up. The [earnings calendar](/tools/[earnings calendar](https://voledge.io/dashboard/earnings)-calendar) is the first cross-check before sizing.

**DASH** and **SNAP** both rank 76, but the absolute vol levels diverge sharply: DASH at 74.9% IV, SNAP at 103.5%. Same rank, different trade — DASH is a contained range scaling rich, SNAP is structural. **AFRM** (75, 96.5% IV) and **QCOM** (67, 58.8% IV) round out the actionable list. QCOM's +11.3% session and elevated rank in a name that doesn't usually carry triple-digit IV suggests a binary catalyst worked through — IV crush candidates often surface at this stage, but the [full IV Rank screener](/tools/iv-rank-screener) needs to confirm direction before fading.

## GEX Regime and Key Levels

Today's GEX levels frame the index pin clearly. **NVDA** at $208.27 closed within $0.77 of its call wall and max gamma strike (207.5), with $80.7B net GEX concentrated at that strike — a textbook pin if it holds, a clean break if it doesn't. **AAPL** at $271.06 is sitting on its 270 stack (flip, max gamma, put wall, and call wall all at 270, $11.5B net GEX). **TSLA** at $376.30 is trading above its 375 call wall with -$4.8B net GEX at the 357.5 strike below — the asymmetry favors continuation unless it falls back through 375. The [GEX dashboard](/tools/gex-dashboard) carries the full strike-by-strike breakdown.

## What to Watch Today

The pins at NVDA 207.5 and AAPL 270 will dictate whether QQQ holds its 664 max gamma. With dispersion concentrated in single names rather than the indices, any unwind in chip vol — particularly ARM and QCOM — pulls the average IV rank lower without changing the index regime. The setup to watch is IV crush in the names that gapped, not breakdown in the indices.
