New
- JGEX Heatmap — See gamma concentration across the whole options chain at a glance with the new JGEX Heatmap, a panel docked under the chart that maps every key strike against upcoming expirations. Green cells mark call-side gamma and red cells put-side, with color intensity showing the size of whichever value you pick — Gamma, Open Interest, or Premium — and a gold outline highlighting the strongest gamma strike for each date. Choose which expirations to include, how many strikes to show (up to the full chain), and optionally overlay call/put rank labels and open-interest change badges. It updates live during the session and remembers your settings per chart tile.
Improved
- More JGEX/JDEX Strikes — The JGEX and JDEX overlays can now plot up to 20 strikes per side, up from 10, for a deeper view of the structure around price.
Changed
- Historical Strike Hover Retired — Previously, hovering over a past candle could show a snapshot of what the top gamma (JGEX) and delta (JDEX) strikes looked like at that earlier moment, toggled on with a "History Mode" switch on the gamma and delta panels. We've retired this historical strike-hover feature. The snapshots it showed were only captured periodically rather than moment-for-moment, which could be misleading, and it added storage and upkeep for a view very few traders used. Your live, current gamma and delta strikes are completely unaffected — the on-chart bars, the real-time updates, and every current-strike readout keep working exactly as before. Only the ability to hover a past candle and see its historical strike snapshot has been removed.
