What's New

Latest updates, features, and improvements to GammaFlip.io

Changelog

[February 26, 2026] - Expected Move Bands & Marker Multi-Selection

Added

  • Expected Move Bands (Premium): IV-based probability cones (±1σ, ±2σ) overlaid on the OHLC chart, showing where price is statistically likely to move by expiration. Computed from OI-weighted ATM implied volatility using a log-normal model. In TOTAL mode, a single cone is drawn from the expiration closest to 30 DTE.
  • Marker Multi-Selection: Positive, Negative, and Absolute GEX marker groups now support multi-select — toggle individual markers on/off for finer control over what's displayed on both OHLC and GEX by Strike charts.

[February 23, 2026] - In-App Help & Blog Updates

Added

  • Contextual Tooltips: Hover over chart markers and key UI elements for instant explanations
  • Searchable Help Drawer: Browse and search all GEX concepts, markers, and chart types from a single panel
  • Guided Tour: Step-by-step interactive walkthrough for new users to learn the interface
  • Blog: "Max Pain Explained": New article covering what Max Pain is, how it's calculated, where it falls short, and why the Gamma Flip Point offers a real-time alternative

[February 19, 2026] - GEX Time Machine & Chart Improvements

Added

  • GEX Time Machine (Premium): Replay historical GEX snapshots up to 7 days back. Control playback speed, jump to any date via a date picker, and filter by expiration to see how gamma structure evolved over time.
  • OHLC View in Replay: Switch to candlestick view while replaying — overlay price action on top of historical gamma levels at any point in history.
  • Shareable Replay Links: Capture and share a specific historical moment via URL. The full replay state (date, asset, expiration, chart mode) is encoded in the link.

GEX Replay

OHLC Replay

Improved

  • Regime Marker Group: Stability and Volatility markers are now grouped under a single "Regime" toggle for a cleaner chart. Enable or disable all key gamma reference levels at once.
  • GEX by Strike Bar Widths: Bars now adapt to the actual spacing between strikes, eliminating visual gaps when strike distribution is irregular.
  • Smoother Transitions: Charts now transition cleanly when switching assets, expirations, or modes — no more flickering or blank states between loads.
  • Asset Selector: Replaced with a native dropdown for faster and more reliable interaction.

[February 4, 2026] - Asymmetry Simplification & UI Reorganization

Improved

  • Simplified Asymmetry Calculation: Asymmetry now uses pre-calculated GEX values from "GEX by Strike" instead of recalculating gamma via Black-Scholes
  • Faster computation (~3x speed improvement)
  • Perfect consistency between Total GEX and Asymmetry (Upside + Downside = Total)

  • Simpler to understand: just sum of absolute GEX above/below current price

  • UI Reorganization: Moved Bias/Asymmetry panel from Gamma Profile to GEX by Strike tab

  • Better conceptual grouping: Snapshot metrics (Total GEX + Bias) separate from Forecast tools (Gamma Profile)
  • Bias now appears in rotating panel on Strike view alongside Total GEX and Max Pain
  • Updated in-app guides to reflect new location
