How It Works

Options markets often lead equity moves. Fin45 monitors real-time options flow for unusual activity: large sweep orders, block trades above open interest, aggressive bid-side buying, and significant put/call ratio shifts. These signals often precede major price moves by 1–5 days.

Frequently Asked Questions

What counts as "unusual" options activity?

Transactions exceeding 5x average daily volume, sweeps across multiple exchanges at the ask, and significant open interest changes relative to the 20-day average.

How far ahead do options signals typically lead?

Based on Fin45's backtesting, unusual options activity precedes significant equity moves by 1–5 trading days on average, with highest alpha in the 2–3 day window.

Does Fin45 trade options directly?

No. The current experiment trades equities only. Options flow is used as a leading indicator for stock direction, not as a direct trading instrument.
