Nightwatch is an options market-structure platform built for U.S. equity market participants. It analyzes options activity to estimate dealer positioning and highlight price levels where hedging may cause prices to stall or volatility to accelerate. Its tools serve both active 0DTE traders and swing or longer-term traders, while providing market context for stocks, ETFs, options, and related index futures.

The Dealer GEX Chart displays intraday key levels and options trades directly on price charts, with live updates and split-screen comparisons. Dealer Heatmap maps estimated positioning across strike prices and expirations over the next 90 days. Users can also track live options flow across the market, analyze implied volatility, and practise with historical 0DTE sessions in Replay Lab.

Ask APEX, Nightwatch’s AI structure assistant, explains current chart readings and terminology without issuing trade signals or making decisions for users. Pro subscriptions include research reports, a Data API, and hosted MCP access for connecting Nightwatch data to code and AI tools.
