Greek Exposure Projection
Dealer-signed charm, gamma and vanna across a price by forward-time grid. Each cell is the net dealer exposure if spot sat at that level at that time, summed over the option chain and signed per strike from live taker flow. Diverging color marks where dealers must add or shed delta to stay hedged.
Pick the Greek with the selector. Charm is the time-decay channel (its magnitude scales as 1/τ into expiry), gamma the price channel, vanna the volatility channel. Left of the NOW line is realized spot; the right side projects the latest snapshot onto the nearest flow-covered 08:00 settlement, a hedging map, not a price forecast. It assumes today's book holds; to see what traders actually added or removed into that book, hour by hour, open Greek Repositioning, and for the standing level of exposure by strike, see Greek Exposure Surface.
How the three differ
| View | Lens | Answers | Options traders should watch for |
|---|---|---|---|
| Greek Exposure Surface | Level · by strike | Where risk sits by strike, and how it decays into expiry. | Strike walls and gamma pins, and which strikes decay fastest into expiry. |
| Greek Repositioning | Flow · by cohort | Where traders added or removed risk, by cohort, over the last day. | Fresh adds and cuts. A whole column lit means a coordinated multi-Greek move. |
| Greek Exposure Projection | Hedge-flow · by price | What dealers must do to stay hedged, by price, into settlement. | Gamma-flip, charm-neutral and vanna-neutral price levels. |
Each view has its own colour scale, some configurable, so a colour is not one meaning across them. Read the legend on the chart itself.
