How to install the NinjaTrader indicator

Install the Gamma Axis gamma-levels indicator in NinjaTrader 8 and connect it with your API key - in about 3 minutes.

NinjaTrader 8 is the one platform where the Gamma Axis levels update on their own: install the indicator once, paste your API key, and the call wall, put wall, HVL and magnets refresh through the session. It takes about 3 minutes - watch the video, or follow the steps below.

Before you start

The indicator is available to subscribers. From your account, download SPX_Evolution_NinjaTrader.zip and copy your personal API key (Copy button).

Install in NinjaTrader 8

Open NinjaTrader 8. In the Control Center: Tools → Import → NinjaScript Add-On…
Select the downloaded SPX_Evolution_NinjaTrader.zip and confirm. NinjaTrader imports the indicator.
Open an ES or NQ futures chart, right-click → Indicators…
Find SpxEvolutionLevels in the list and add it.
In the settings, paste your API key, pick the matching instrument (ES or NQ), and apply.

That is it

The gamma levels plot automatically and refresh through the session - call resistance, put support, the HVL and magnets appear as labelled lines. The indicator only updates while your subscription is active.

FAQ

Where do I get the indicator?

From your account page, as a subscriber: download the NinjaTrader file and copy your personal API key, then import the file into NinjaTrader 8.

Does it refresh automatically?

Yes. NinjaTrader is the one platform where the indicator pulls the daily levels from your API key and updates through the session, as long as your subscription is active.

ES or NQ - which set do I load?

Match the instrument to your chart: ES for the S&P map, NQ for the Nasdaq map. You pick it in the indicator settings alongside your API key.
