ATR Ratio Z-Score
Volatility regime signal using the ratio of short-term ATR to long-term ATR, then normalizes it using a Z-score.
It measures how unusual the current short-term volatility is relative to long-term volatility.
Conceptually:
Short ATR (5) → recent volatility
Long ATR (20) → baseline volatility
Ratio = Short ATR / Long ATR
If the ratio rises, recent volatility is expanding.
If the ratio falls, volatility is compressing.
Then you standardize it using a Z-score, so you know how extreme the condition is relative to the last 50 periods.
