NinjaTrader 8 GEX Indicator
Live GEX levels and per-strike distribution right on your NinjaTrader 8 chart — without switching software.
Why use HermesGEX on NinjaTrader 8
The HermesGEX indicator for NinjaTrader 8 draws dealer gamma exposure onto your intraday chart: Zero / Long / Short Gamma lines, call/put walls and a right-side per-strike distribution panel, auto-refreshed roughly every 5 seconds. ES / NQ intraday traders never have to leave their order-entry and risk environment to read GEX.
Rival tools make you open a separate terminal just to see GEX. HermesGEX doesn't — it overlays institutional-grade gamma exposure, call/put walls and per-strike distribution right on the chart you already trade on. Your execution, risk and data feed stay exactly where they are.
What you get
- Zero / Long / Short Gamma lines (incl. 0DTE)
- Call / Put walls plus HVL and other derived levels
- Right-side distribution: Gamma Profile or GEX by volume
- Tactical HUD: regime/playbook call + vol microstructure + EOD magnet + reading ladder (off by default)
- Large, adjustable price-level labels
- Browser-based device authorization to prevent account sharing
