Dealer Greek Term Structure
Net dealer gamma, delta, vega, theta, vanna and charm for each upcoming expiry in the current option book.
The Dealer Greek Term Structure widget groups the current options book by expiry and shows one net dealer-exposure bar for each date. Choose Gamma, Delta, Vega, Theta, Vanna or Charm without putting unlike units on the same axis.
What it shows#
| Control or readout | What it means |
|---|---|
| Greek | The exposure shown on the chart and in the expiry list |
| Blend / OI / Vol | Engine positioning, printed open interest, or today's session volume |
| DTE | The furthest expiry included, from 7 through 90 days |
| Green bar | Positive net dealer exposure at that expiry |
| Red bar | Negative net dealer exposure at that expiry |
| Total | The selected exposure summed across the visible expiries |
Gamma is shown in dollars per 1% move, Delta in dollar delta, Vega in dollars per volatility point, Theta in dollars per day, Vanna in delta dollars per volatility point, and Charm in delta dollars per day. The unit changes with the selected Greek and is printed beside the headline value.
How to use it#
- Start with Gamma to see whether one near-term expiry dominates the current dealer regime or whether the sign is consistent farther out.
- Switch to Vanna or Charm to locate the expiries where volatility or time decay has the largest current delta effect.
- Compare OI with Vol to separate established positioning from today's activity. Use Blend when you want the same positioning view used by the main engine widgets.
- Increase the DTE window to check whether a front-expiry extreme persists through later dates or quickly reverses.
Every bar is calculated from the option book available now. The widget does not project how positions or price will change, and it is not available in Replay because historical full-chain Greek terms are not stored.
The gamma flip, walls, vol trigger and max pain for each upcoming expiry, against the current price.
Dealer exposure for any greek at every strike, colored by days to expiry, with the walls, flip and max pain.
Which expiries the levels cover, and why they move during the day.
