NR7 (Narrowest Range of 7 days): today's range is the smallest of the last 7 trading days. A clear volatility contraction. Explosive breakouts follow these compressed days more often than random chance, especially when combined with trend alignment.

💡 Pro Tip
NR7 alone is a mediocre signal. Combined with trend alignment (above/below EMA 20), it becomes substantially more reliable. You're catching volatility expansions in the direction of the existing trend, not random breakouts from compression.
