Validation & sources
A risk preflight should predict downside risk, not price direction. We backtested the live scoring math (model v1.3.0: winsorized level z + trend z squashed by tanh, plus a 12-lookback trend-regime vote and dip-in-uptrend conditioning) over 9,122 trading days of FRED history: 1990 to 2026, four bear markets. Full sample (NASDAQ, forward 20 days):
The middle tercile lands in between (17.7% vol, 6% drawdown odds), so the separation is monotonic across the whole 36 years, including the 2000, 2008, 2020 and 2022 bears. Earlier model versions only separated in the recent cycle; v1.3.0's trend-regime vote (12 momentum lookbacks, an approach validated in live trading research) is what fixed the full-sample robustness. In the recent cycle the spread is wider still: 28.4% vs 15.1% vol, 18% vs 2% drawdown odds. Backtest uses a 4-input proxy with full 36-year history; the live engine runs ~50 inputs including credit spreads, the dollar, and financial-stress indices.
Where a pro index isn’t free (MOVE, ISM, CRB) we build a transparent proxy and say so. What we never do: hand-edit a score, paste a number, or override the engine. The Send Meter formula: 50 + 12·MacroCore − Fragility − Session − Options + Confirmation − DataConfidence.
