Unusual Options Activity — Volume and Flow Outliers

As of April 21, 2026 (end-of-day snapshot). Pages update daily after the market close.

This screen surfaces the day's most active options names and lets you re-rank them by breadth of unusual activity. The pre-rendered table below is ranked by total contract volume on the most recent EOD snapshot — a simple activity proxy for search indexing. The interactive scanner panel (below) ranks the same universe by a stricter breadth signal: the number of individual contracts on each ticker's chain that traded at vol/OI > 2 AND volume ≥ 500. Names at the top of the interactive list have multiple strikes trading genuinely hot, not just one big block. That breadth is what distinguishes a catalyst-driven positioning build from an isolated trade.

Methodology

The pre-rendered table ranks tickers by total_volume descending on the most recent EOD snapshot of option_ticker_snapshots (liquidity floor: total_oi ≥ 500). The interactive scanner below ranks by unusual_contract_count — a per-ticker breadth count of contracts where volume/OI > 2 AND volume ≥ 500. Breadth is the better signal for 'truly unusual' because chain-wide volume/OI averages get diluted by quiet strikes and rarely clear a meaningful bar. Updated daily after close. All data is end-of-day OPRA aggregates.

Frequently Asked Questions

Why does the interactive scanner rank differently than the table above?

The pre-rendered table is ranked by total volume as an indexable activity proxy. The interactive scanner uses the stricter breadth-count metric — number of contracts with vol/OI > 2 AND vol ≥ 500 — which is more aligned with what "unusual activity" actually means. Breadth tells you whether multiple strikes across the chain are trading hot or just one big block made the volume number look interesting.

What qualifies a contract as "unusual"?

A contract counts if its volume/OI ratio exceeds 2 AND absolute volume is at least 500. The ratio ensures today's activity is meaningful relative to existing positioning; the volume floor filters out noise from tiny-OI contracts where a handful of trades produce extreme ratios.

Does unusual activity predict price moves?

Not reliably. It signals that someone is positioning with conviction. Whether the trade is directional, a hedge, informed, or speculative — and whether it ultimately pays off — depends on the catalyst. Use it as a research starting point, not a standalone signal.

Is the data real-time?

No — all public screener data is end-of-day for OPRA licensing reasons. Real-time options data is available to authenticated users with their own Tradier or tastytrade BYOK credentials.
