Hindenburg Omen

The Hindenburg Omen highlights periods of internal market stress — when both new 52-week highs and new lows expand while the NYSE remains in an uptrend.
This condition often precedes major corrections or volatility spikes by revealing divergence beneath the surface of an advancing market.

The indicator triggers when four classic breadth rules align: elevated highs and lows, a positive trend, a negative McClellan Oscillator, and a highs-to-lows ratio under 2:1.
Use it on broad indices (NYSE, S&P 500) as an early-warning context tool, NOT a standalone sell signal.
