The Best SPX 0DTE Options Tools (2026)
There is no single best tool for SPX 0DTE trading - there are different jobs: dealer-positioning levels, flow discovery, strategy construction, screening, and continuous market-structure reading. This roundup (written by zdte.ai, so read our entry with that in mind) covers what each established tool genuinely does best.
This page is written by zdte.ai. We state each tool's genuine strengths plainly, avoid pricing (it changes — check each provider), and note that all trademarks belong to their owners; zdte.ai is not affiliated with the companies mentioned.
SpotGamma - dealer-positioning levels, multi-ticker
The most established name in retail dealer-positioning analytics. Daily levels across indices and many single stocks, strong written commentary, an active community, and educational content that shaped how retail talks about gamma. Best for: swing and index traders who want pre-computed levels across multiple tickers every morning.
Unusual Whales - options-flow discovery, market-wide
The best-known flow platform: real-time notable-trade alerts across thousands of tickers, market dashboards, and widely-cited data journalism. Best for: traders who want to discover unusual activity anywhere in the market, fast.
Menthor Q - levels across asset classes
Quant levels (gamma, key strikes) across equities, indices, futures, and FX, with integrations that bring levels into charting platforms traders already use. Best for: multi-asset traders who want positioning-derived levels inside their charting workflow.
OptionStrat - strategy building and visualization
The go-to free-to-start payoff visualizer: build any options structure and see profit/loss, Greeks, and probabilities, plus a flow product. Best for: planning and understanding specific trades - the "what happens if" tool, complementary to any analytics service.
Market Chameleon - screening and options data breadth
Deep options data and screeners: unusual volume, earnings history, volatility comparisons, and statistics across the whole listed market. Best for: research-heavy traders who want to screen and compare before committing to a trade.
zdte.ai - continuous SPX 0DTE market structure (that’s us)
Full disclosure: this is our platform. zdte.ai does one job - a continuous, intraday structural read of the SPX 0DTE complex: an estimate of dealer positioning, gamma regime, call and put walls, and pins, updating as positioning changes through the session. Around it sits a free public layer: forensic research papers reconstructed from our own recorded telemetry, a Field Guide, and a glossary. Best for: traders whose day is SPX and same-day options, who want the mechanics behind each session rather than levels alone. Positioning figures are proprietary estimates and are labeled as such.
How to choose
Match the tool to the job: levels across many tickers (SpotGamma, Menthor Q), flow discovery (Unusual Whales), trade construction (OptionStrat), screening and data (Market Chameleon), continuous SPX structure (zdte.ai). Serious 0DTE traders commonly pair one breadth tool with one depth tool. Features and pricing change frequently - verify with each provider before subscribing.

Frequently asked questions
What does an SPX 0DTE trader actually need?
At minimum: a way to understand the day’s structure (where the walls and the volatility regime sit), a way to construct and risk-check the trade, and the discipline to wait when the structure favors neither side. Different tools cover different parts of that.
Are dealer-positioning numbers from different tools comparable?
Directionally, often; precisely, no. Dealer positioning is not directly observable, so every provider publishes an estimate built from open interest and flow under different assumptions. Treat all of them - including ours - as estimates.
Is this roundup independent?
No - it is written by zdte.ai. We have tried to state each competitor’s genuine strengths plainly and to confine our own entry to what the platform actually does. Verify everything with the providers directly.
