Why it moved

TA on this site tells you which classic rule printed and whether it historically paid. It does not say why the stock moved. Options positioning is often why. SpotGamma maps that.

Optional: SpotGamma free tools. Nothing here is trade advice.

Honest caveats

  • Past โ‰  future. Everything here is a historical measurement on daily bars, not a prediction and not investment advice.
  • No costs modeled. Forward returns are close-to-close with no commissions, slippage or borrow.
  • Overlap bias. Signals that fire in clusters get credit for the same move more than once.
  • Small samples. A row with fewer than 10 firings is anecdote, not evidence.
