Projects

Open one to use it, or read the code and copy it.

Code is a hypothesis. Evidence is the standard.

Every tool starts with a question about how the market behaves. The job is to turn that question into explicit rules that can be inspected, tested and improved.

  1. Observe

    Define the market behaviour or problem worth investigating.

  2. Formalize

    Translate the idea into transparent logic and measurable conditions.

  3. Validate

    Test across symbols, timeframes and market conditions. Document the limits.

  4. Iterate

    Publish revisions with clear notes instead of hiding what changed.
