Dealer Edge Charm Lens
The Charm lens is the fourth heatmap view on Dealer Edge. It shows time-decay drift exposure by strike - useful near expiry when delta moves faster than gamma pinning alone explains.
Four lenses on one grid
| Lens | Colors | Best for |
|---|---|---|
| GEX | Red / green | Dealer gamma regime, anchor and flip reads |
| Vol | Red / green | Options volume concentration by strike |
| VEX | Red / green | Volatility exposure |
| Charm | Purple / amber | Time-decay drift near 0DTE and weekly expiries |
Charm uses a different color ramp from GEX so you do not confuse greek lenses:
- Negative charm: purple (
#8B5CF6) - drift down - Positive charm: amber (
#D9A42A) - drift up
When to use Charm
Switch to Charm when:
- You are trading 0DTE or front-week options
- GEX says pin but price keeps drifting through your strike
- You need to size and stop based on time, not gamma alone
GEX proposes regime. Charm adds how time decay may move deltas before expiry.
Web and mobile
Charm is available on web (Trade Echo dashboard) and mobile (Markets → Dealer Edge → lens selector). Pro mode on mobile remains GEX-only; use the main heatmap toggle for Charm.
