What Are Signals?

Short answer: Signals are what an Investor Skill watches and how much each one counts. In invest.md they are weighted tokens (high / medium / low) with optional direction, threshold, frequency, and source. They are inputs to judgment — not automatic buy orders.

Anatomy

signals:
  fundamental:
    roic:
      weight: high
      frequency: annual
      direction: higher-is-better
      threshold: "> 15%"

A Buffett-style skill weights owner earnings and ROIC. A Livermore skill weights breakout confirmation and volume. A Willy Woo skill weights on-chain holder behavior. The plugin layer is how those numbers actually arrive.

Signal vs filter vs execution

• Signal — evidence that updates conviction

• Filter — binary gate

• Execution — only after thesis + limits
