Hermēs DocumentationTradingView integration
A free Pine script that draws daily GEX levels (call wall / zero gamma / put wall / HVL) onto your TradingView chart.
The TradingView integration is a free, public Pine script that draws your daily GEX levels — call wall, zero gamma, put wall, and HVL — onto your own TradingView chart and shades the background by regime.
Open it at /tools/tradingview — no login required.
Who can use it
- Free / public, no login, no paywall.
- The equity-index levels published here are ~30 min delayed; for real-time levels sign in and use HuntingFlow.
Why "paste numbers" instead of auto-sync
TradingView's Pine scripts can't fetch arbitrary HTTP, so they can't pull our live levels directly. The workaround: paste 4 numbers into the indicator settings each morning and the script auto-draws and shades by regime. For auto-drawn levels inside the terminal, use HuntingFlow.
Three-step setup
Download and load the script
On /tools/tradingview, download hermes-gex-levels.pine → open TradingView's Pine editor → paste → Add to chart.
Enter today's 4 numbers
Copy your ticker's Call Wall / Zero Gamma / Put Wall / HVL from the on-page levels table (or the share card) into the indicator settings.
Watch the auto-draw
The indicator draws labelled horizontal lines and shades the background by regime: above Zero Gamma = long gamma / range; below = short gamma / trend.
For automation: the page also exposes a machine-readable JSON levels feed you can poll on a schedule:
GET /api/v1/public/levels?ticker=SPY.
Before the open there is no volume yet, so the response has basis: "oi": Call / Put Walls come from open interest and zero_gamma, hvl and regime are null. It switches to "vol" automatically after the open.
ES / NQ futures prices, intraday history and every field are covered in Free key-levels API.

Frequently asked questions
Is the TradingView integration paid?
No. It is a free, public Pine-script download page with no login required.
Is it a webhook or a live overlay?
Neither. Because Pine can't fetch arbitrary HTTP, it's a "paste 4 numbers each morning" workflow — the script then auto-draws the lines and shades by regime.
