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 screener](https://voledge.io/iv-rank) Stocks Today: NOW, GM, and RBLX Surface in a Dealer-Pinned Market

**Meta description:** High IV rank stocks today — NOW at 63, GM at 56, and RBLX at 54 lead the board while SPY [GEX dashboard](https://voledge.io/dashboard/gex) hits +$313B and dealers pin indices in a tight range.

---

SPY dealer gamma is concentrated at a single strike — $313.3B of positive GEX stacked at 659, with the flip strike, max gamma, and call wall converging on the same level. That kind of positioning compression means one thing: dealers are defending this price with everything they have.

## Market Volatility Regime: VIX and Term Structure

The implied volatility regime is subdued. Average IV Rank across the board sits at 35, with only three names clearing 50. Breadth is flat — 26 advancers against 22 decliners on a +0.11% average move. This is a textbook positive-gamma, low-vol environment.

GEX levels today confirm it across every major index. **SPY** carries +$313.3B with a put wall at 658 and call wall at 659 — a one-dollar range of dealer defense. **QQQ** mirrors the setup at +$236.8B with gamma concentrated at 587-588. **NVDA** adds +$68.8B with its flip at 175 and call wall at 177.5. When dealers are this long gamma, they buy dips and sell rips, compressing realized volatility below what the options market is pricing. Mean-reversion is the dominant force until something breaks these levels.

The sole exception: **TSLA** at -$2.6B GEX with no defined flip strike. Today's -2.3% move is consistent with a short-gamma environment where dealer hedging amplifies rather than dampens. More on that below.

## Top IV Rank Setups Today

Three names on our [full IV Rank screener](/tools/iv-rank-screener) are worth examining.

**NOW** leads at IV Rank 63 with IV percentile at 100 — meaning current implied volatility of 65.7% exceeds every reading in its recent lookback window. ServiceNow isn't reporting imminently, which makes this elevation notable. The data favors premium sellers: elevated rank without a defined catalyst suggests the market is pricing in more movement than realized vol is likely to deliver, particularly in this positive-GEX macro regime.

**GM** prints IV Rank 56 with IV percentile also at 100 and current IV at 44.0%. Auto names have been volatile on tariff headlines, and GM's +1.1% move today suggests the stock is catching a bid even as implied vol stays rich. For traders running an options volatility screener, the combination of elevated IV Rank and positive price action creates a setup where credit spreads collect premium while the underlying cooperates directionally.

**RBLX** sits at IV Rank 54, current IV 77.7%, and is the day's weakest large-cap name at -4.6%. High implied volatility rank paired with a sharp down move is a different profile — the market may be correctly pricing risk here. Traders considering premium sales in RBLX need to weigh whether this is a vol overshoot or the start of a sustained move. Check the [earnings calendar](/tools/[earnings calendar](https://voledge.io/dashboard/earnings)-calendar) for any upcoming catalysts before sizing.

## GEX Regime and Key Levels

The [GEX dashboard](/tools/gex-dashboard) shows a rare alignment: four of five tracked symbols carry positive gamma with tightly clustered support and resistance. TSLA is the outlier. With the put wall at 350 and price at 352.82, TSLA is trading directly in the dealer short-gamma zone. Below 350, hedging flows accelerate the move lower. Above 352.5, the call wall provides a ceiling. This is a name where directional moves carry more than they do in the broader pinned market.

## What to Watch Today

With GEX this concentrated and IV Rank this compressed, the session likely grinds in a narrow range — unless an external catalyst forces a break below SPY 658 or QQQ 587. Those are the trip wires. If they hold, premium sellers collect. If they break, the regime shifts fast.
