  • Every consequential number has a source, a time and an age. If it does not, we say that.
  • Missing data is reported, not hidden. A gap, a delay or a thin sample is stated in the answer.
  • Inference is labelled. Anything that guesses at intent (for example a bullish or bearish label on an options trade) is marked as an inference.
  • No trading. TraderOS analyses and tests. It never places orders.
  • Not advice. Results describe data and history. Decide for yourself, and size your risk accordingly.
