What is the New Highs New Lows Indicator?
The New Highs New Lows (NHNL) indicator is a powerful market breadth tool used by traders and investors to measure the overall health and momentum of the stock market. It tracks the number of stocks making new 52-week highs versus those making new 52-week lows on a given trading day. This indicator provides insight into whether the market rally or decline is supported by broad participation across many stocks, or if it's being driven by just a handful of names.
NHNL Formula
New Highs: Number of stocks that hit a new 52-week high
New Lows: Number of stocks that hit a new 52-week low
NH/NL Ratio: New Highs ÷ New Lows (values >1 are bullish)

Interpreting NHNL Data
| NHNL Pattern | Interpretation |
|---|---|
| Rising New Highs + Rising Prices | Bullish confirmation - healthy uptrend with broad participation |
| Rising New Lows + Falling Prices | Bearish confirmation - downtrend with widespread selling pressure |
| Falling New Highs + Rising Prices | Bearish divergence - rally may be weakening, potential top forming |
| Rising New Highs + Falling Prices | Bullish divergence - decline may be ending, potential bottom forming |
| NH/NL Ratio > 2 | Strong bullish breadth - market has significant upward momentum |
| NH/NL Ratio < 0.5 | Strong bearish breadth - market under significant selling pressure |
NHNL vs Advance Decline Line
While both are market breadth indicators, they measure different aspects of market participation. The Advance Decline Line tracks daily advancing vs declining stocks regardless of their position relative to their 52-week range. The NHNL indicator specifically focuses on stocks at their extremes - those making new yearly highs or lows. This makes NHNL particularly useful for identifying market extremes and potential turning points, while the AD Line is better for tracking day-to-day market participation.
New Highs New Lows Calculator FAQ
- What is the New Highs New Lows indicator?
- The New Highs New Lows (NHNL) indicator is a market breadth tool that tracks the number of stocks making new 52-week highs versus those making new 52-week lows. It measures overall market strength by showing how many stocks are participating in upward versus downward trends. A positive Net New Highs value indicates bullish market breadth.
- How is Net New Highs calculated?
- Net New Highs is calculated using the formula: Net New Highs = New Highs - New Lows. When more stocks are making new highs than new lows, the value is positive (bullish). When more stocks are making new lows, the value is negative (bearish). The cumulative sum tracks the trend over time.
- What does the New Highs/New Lows ratio tell us?
- The NH/NL ratio (New Highs divided by New Lows) provides a normalized view of market breadth. A ratio above 1 indicates more stocks hitting new highs than lows (bullish). A ratio below 1 indicates more new lows (bearish). Extreme readings often signal overbought or oversold conditions.
- How do I use NHNL data in trading?
- Traders use NHNL to confirm market trends and spot divergences. When the market index rises but new highs decline, it signals weakening breadth (bearish divergence). Conversely, rising new highs during a market pullback suggests underlying strength. NHNL is particularly useful for identifying market tops and bottoms.
- Where can I find New Highs and New Lows data?
- New Highs and New Lows data is available from major exchanges like NYSE and NASDAQ. Financial websites like Yahoo Finance, Bloomberg, Barchart, and most broker platforms provide daily NHNL statistics. The data is typically reported at market close for each trading day.
