Yes, there are free alternatives that provide similar Gamma Exposure (GEX) data for E-mini traders.
One option to explore is AlgoStorm, which offers a free daily dashboard displaying key SPX Gamma levels (Call Wall, Put Wall, and Gamma Flip) without requiring a login or subscription.
As an additional option, SpotGamma provides a free, simplified daily SPX Gamma Exposure chart.
For an E-mini (ES/MES) trader using NinjaTrader 8, the workflow to integrate this data is straightforward and precise:
1. Retrieve Levels: Each morning, note the SPX Call Wall, Put Wall, and Gamma Flip prices from the chosen free dashboard.
2. Apply to Chart: Open your ES or MES continuous contract chart in NinjaTrader 8 and manually draw these specific price levels as horizontal lines. (SPX options levels map directly to ES/MES price charts without conversion).
3. Filter for Stability: If your focus is swing or trend trading, change the expiration filter on the dashboard from "0DTE" or "Weekly" to "Monthly" or "Quarterly". This provides stable, structural support and resistance levels that do not shift every week.
This approach allows you to map institutional options positioning onto your futures charts without the need for a paid subscription service.
