What's New

Latest updates, features, and improvements to GammaFlip.io

Changelog


[June 1, 2026] - Small Features That Make GEX Easier to Read

Added

Improved

  • Strike chart controls tidied up: Bar Width and Strike Concentration moved into the per-chart ⚙ Controls popover (Strike Concentration now a 90/95/99/100 selector). Your setting carries over.

Fixed

  • Heatmap on mobile: removed the black side bands, tighter margins.
  • Control help icons now open the matching help entry.

[May 28, 2026] - A New Way to Read GEX

Added

  • Chart UI Redesign: The chart picker is reorganized around four time-based questionsNow ⚡, Expiry 📅, History 🕰️, Forecast 🎲 — with secondary controls that adapt per category. A new Dealer Pulse rail on the left keeps three live cards visible across all charts: Flip Point, Hedging Pressure (Net GEX), Absolute GEX. Asset / exchange / expiry collapse into a single context-picker pill, and rare controls move into a per-chart ⚙ panel. Open the redesigned app.

  • Blog: A New Way to Read GEX: The mental model behind the four categories and how to read the Dealer Pulse rail. Read: A New Way to Read GEX.


[May 22, 2026] - Monte Carlo Simulator

Added

  • Monte Carlo Simulator: New chart that answers how likely is BTC to be above (or below) a price on a specific date? Runs 20,000 GEX-warped price paths to your chosen expiry; hover any price to read the chance of finishing above/below it plus the symmetric percentile cone. In-chart stats card shows p10 / p50 / p90, σ, and skew. Three intensity presets — Light / Normal / Strong — control how much the GEX surface bends paths. Open the Monte Carlo view.

  • Blog: Monte Carlo Simulator: How to read p10/p50/p90, why it differs from the ±1σ cone, and a worked BTC example. Read: Monte Carlo Simulator: Forecasting Where BTC Might Land by Expiry.


[May 18, 2026] - Flip Point on Heatmap

Added

  • Flip Point line on Heatmap: The Heatmap now overlays the Gamma Flip Point (F) as a magenta line that tracks through time, dividing the chart into Jumpy (below F) and Sticky (above F) regimes. Uses the same F color as on every other GEX chart so the boundary lines up across views. Both overlays are labeled at the right edge — the price track shows the coin symbol (e.g. BTC), the flip track shows F — so the two can't be confused at a glance. Toggle the overlay via the new FLIP control in the chart toolbar (visible only in Heatmap view). Default on; preference persists. Try it on the Heatmap. Long-form walkthrough using ETH from May 11–18: Flip Point on the Heatmap: Reading Sticky vs Jumpy Behind the Colors.

  • Blog: TOTAL vs Specific Date: A new long-form post on the GEX expiration selector — when TOTAL answers your question vs when a specific date is what you actually want, plus a one-minute diagnostic that tells you whether they're showing the same thing. Read: TOTAL vs Specific Date: Reading the GEX Expiration Selector.
    TOTAL vs Specific Date — Reading the GEX Expiration Selector. Calendar pages converging into a TOTAL line above a bar chart.


[May 12, 2026] - GEX Academy Track 2 — Options Curious

Added

  • GEX Academy Track 2 — Options Curious: 8 lessons that explain the mechanism behind GEX — for traders who finished Track 1 and want the "why" behind the levels. Covers an options primer in 5 minutes (call/put/strike/expiration), why dealers must hedge, what gamma actually is (no formulas), reading the GEX-by-Strike chart end-to-end, the Flip Point as a fulcrum, positive vs negative gamma regimes, Max Pain in context (when it pins and when it lies), and a 5-step end-to-end read on BTC. Start at /academy/en/options-curious.

[May 7, 2026] - Academy in Brazilian Portuguese

Added

  • Academy PT-BR: Track 1 (Perp Trader) is now available in Brazilian Portuguese. Use the EN | PT-BR toggle on any Academy page to switch.

[April 29, 2026] - GEX Academy

Added

  • GEX Academy: New educational hub at /academy — structured lessons that teach you to read GEX as a perp trader. Track 1 (Perp Trader) launches with 11 published lessons covering the Flip Point, positive/negative walls, |GEX| markers (A1/A2/MV), confluence setups, the heatmap, TA overlay, the Friday reset cycle, when GEX levels stop mattering, and a 2-minute pre-trade scan that ties it all together. More tracks (Options-Curious, Active Options, Pro) are coming.

Changed

  • Learn page renamed to Glossary: The /learn page is now /glossary to reflect what it is — a reference of every chart, marker, and metric. Old /learn URLs redirect automatically. Glossary is the lookup tool; Academy is for learning concepts end-to-end.

Improved

  • Glossary search & TOC: Search bar and table of contents now stick to the top as you scroll, so you can jump or filter from any depth in the page. The search input is mirrored across desktop and mobile views.

[April 23, 2026] - Local Timezone Display

Added

  • Local Timezone Toggle: New option in Settings (⚙) → Time to display intraday chart timestamps in your browser's local timezone. UTC remains the default. When enabled, the time suffix becomes (UTC±N) (fractional offsets like UTC+5:30 supported).
  • Applies to: chart subtitles (GEX by Strike, Term, Gamma Profile, OHLC), heatmap hover tooltip + timestamp overlay, intraday (1H) OHLC candles + crosshair, Time Machine slider tooltip.
  • Daily OHLC candles, expiration dates, the delayed-data banner, and pip labels on the Time Machine slider always stay UTC — matches aggregation units and avoids confusion with cross-reference tools, alerts, and the Deribit expiry calendar.
  • Preference persists across reloads; charts re-render in place on toggle — no page refresh needed.
  • DST-aware: hourly charts that span a daylight-saving transition shift each bar by its own offset.

[April 20, 2026] - 25Δ Risk Reversal Metric

Added

  • 25Δ RR (Risk Reversal): New metric in the Term OI view. Computes IV skew per expiration per exchange as IV(25Δ Call) − IV(25Δ Put) in vol points — the crypto-desk standard for implied-volatility skew. Negative = puts richer (fear); positive = calls richer (speculation). Rendered as a line+marker chart with one trace per exchange; legend toggles let you solo venues. See the Learn page for how to read it alongside GEX.

[April 15, 2026] - Pro Tier & Public API

Added

  • Pro Tier (€35/mo): New subscription above Premium. Includes everything in Premium plus programmatic access via the REST API.
  • Public REST API (v1): Endpoints for GEX by Strike and Term Structure across all supported assets and exchanges. Daily limits: 50 requests on trial, 500 on Pro. See the For Developers section on the landing page.
  • API Key Management: Generate and revoke API keys from the Account page. Trial users get 1 key; Pro users up to 5.
  • Upgrade to Pro: Premium subscribers can upgrade with a one-click prorated preview.

Improved

  • Account Page Redesign: Tier-aware layout — Premium users no longer see a misleading "Full access" caption next to an Upgrade-to-Pro card. Trial/Pro users see today's API usage and quota.

[April 13, 2026] - Learn Page Rework & Subscription-Required Access

Added

  • Learn Page Search: Filter-as-you-type search on the /learn page — type a keyword and entries narrow instantly. Category headers hide when all their entries are filtered out.
  • Learn Page Screenshots: Every chart, marker, and metric entry now includes a screenshot so you can see exactly what you're reading about. Complex entries (GEX by Strike, Flip Point, Gamma Profile) include an Annotated variant with labeled callouts — toggle between Annotated and Plain with a single click.

Changed

  • Subscription Required for App Access: The /app and /dashboard pages now require an active trial or Premium subscription. Anonymous visitors and permanent free-tier users are redirected to the subscribe page. This change was necessary to protect platform stability — unrestricted free and anonymous access was driving significant load that degraded reliability for paying subscribers. New accounts still get a 14-day full-access trial, no credit card required.

[March 20, 2026] - Free Tier Access & Premium Gating

Added

  • Free Access to Core GEX Charts: GEX by Strike, Gamma Profile, and OHLC charts are now available to all users — no account required. See real-time gamma data without signing up.
  • Term Structure for Free Users: Term Structure chart is now accessible to free users with Open Interest data visible. GEX metrics and premium markers require Premium.

[March 19, 2026] - Paddle Payments & Simplified Pricing

Added

  • Paddle Payments: New payment provider with improved checkout experience. Existing LemonSqueezy subscribers are fully supported — manage your subscription as usual from the Account page.

Improved

  • GEX NET Line Overlay: The Term Structure chart's GEX NET view now shows a dotted line with diamond markers tracing the net total across expirations. Makes it easy to read the net value even when positive and negative exchange stacks overlap.

Removed

  • Referral Program: Discontinued due to low adoption. The Community Contributor Program remains active — create educational content and earn free Premium access.

[March 17, 2026] - OKX Exchange Integration

Added

  • OKX Exchange Support: OKX is now available as a third exchange alongside Deribit and Bybit. All GEX charts — GEX by Strike, Gamma Profile, OHLC, Term Structure, Heatmap, and Dashboard — now include OKX options data.
  • Select OKX individually or combine with Deribit and Bybit for a complete cross-exchange view
  • OKX data appears in distinct blue in the Term Structure chart, stacked alongside Deribit (green) and Bybit (orange)
  • Available for all supported assets where OKX lists options
  • ~99.5% Market Coverage: Adding OKX brings total crypto options market coverage to ~99.5%.
