About OptionsScreenerPro

OptionsScreenerPro ranks and filters US-listed stocks and option contracts by the activity behind them: option volume against its usual level, open interest and its changes, implied volatility and IV rank, approximate money flow and spread opportunities.

How we work

• Every number shows its source and how delayed it is. Phase 1 uses free and delayed providers and end-of-day data.
• Every column has a written formula in the metric glossary; nothing is a black box.
• An unknown value is shown as “-” with the reason, never as 0.
• We describe activity, not direction: volume and flow never claim to know who bought or sold.

What we are not

OptionsScreenerPro is a research tool. It is not a broker or an investment adviser, cannot place trades and never holds your money or securities.
