GCIGexLevels: Complete Reference Guide
GCIGexLevels: Complete Reference Guide
By GammaContext · Product documentation
GCIGexLevels plots the same GEX levels you see in the portal directly on your price chart:
three structural levels and four intraday levels. Before continuing, activate your Key
(activation guide).
The 7 Levels
Structural (Call Wall, Put Wall, Gamma Flip)
Calculated over all accumulated open interest, regardless of expiration. Active in 0DTE, 1DTE, and ALL.
| Level (UI label) | What it is |
|---|---|
| Call Wall | Strike with the highest concentration of call gamma. Acts as structural resistance. |
| Put Wall | Strike with the highest concentration of put gamma. Acts as structural support. |
| Gamma Flip | Price where the market's net gamma crosses from positive to negative. Marks the regime change. |
Intraday (Long Wall, Short Fuel, Res Call, Sop Put)
Reflect options flow expiring today or tomorrow. Only exist in 0DTE and 1DTE: they hide
automatically in ALL (the three structural levels stay visible).
| Level (UI label) | What it is |
|---|---|
| Long Wall | Wall that brakes the price advance from customer position defense at that strike. |
| Short Fuel | Zone that accelerates price once it's left behind. |
| Res Call | Short-term resistance from call concentration expiring today or tomorrow. |
| Sop Put | Short-term support from put concentration expiring today or tomorrow. |

How It Behaves
- Flicker-free updates: every new value from the feed only updates the affected level. No full recalculation or redraw.
- Live expiration switching: switching from 0DTE to 1DTE or All updates the levels immediately, without reconnecting.
- Self-reconnecting: if the feed drops, the indicator automatically retries the connection and keeps the last visible value in the meantime.
- Zero polling: the indicator receives data by streaming, it never queries the database in a loop.
