Whale Flow Bias

Intraday institutional call vs put accumulation ratio

No intraday whale history yet for this ticker (data accrues during active market hours).

Informational only — not financial advice. Directional bias is derived from observed whale options activity and can be wrong.

Methodology

Gamma walls — strikes with the largest gamma exposure: Black-Scholes gamma × open interest × 100 × spot, summed per strike, calls counted positive and puts negative (naive dealer-positioning assumption — we do not have real dealer flow). Green = net positive (price magnet/support), red = net negative (accelerant).
Gamma flip — strike where cumulative gamma exposure changes sign.
Max pain — strike minimizing the total intrinsic payout of all open contracts at expiry.
Expected move — at-the-money straddle price of the nearest expiry, as a percent of spot.
Tickers: SPY, QQQ, IWM plus the top 10 by whale-flow activity today. Full option chain (all open interest, not just today's trades), recomputed every 30 minutes.

Informational only — not financial advice. These are mechanical computations from public option-chain data and can be wrong or stale.
