How Stryke surfaces it
The screener pulls live chains, ranks contracts by activity score, and exposes filters for delta, days to expiry, and volume to open interest ratio. Pair it with the IV Rank column to find names where options are unusually active and the broader volatility is also stretched.

FAQ
What is unusual options activity?
Unusual options activity describes contracts trading at volumes well above their typical level, often a multiple of average daily volume or open interest. Traders watch it as a possible signal of informed positioning before earnings, news, or large moves.
How does Stryke detect unusual activity?
Stryke compares each contract's intraday volume to its trailing average and open interest, flags volume to open interest ratios above one, and highlights block prints near the ask or bid for sentiment context.
Is unusual options activity a reliable signal?
It is one input, not a standalone signal. Combine it with implied volatility rank, the underlying's technical setup, and upcoming catalysts like earnings before acting.
Does Stryke cover ETFs and indexes?
Yes. The scanner runs across the US equity and ETF universe including SPY, QQQ, IWM, and major sector ETFs.
