High-Low Percent (HL Percent) is a breadth indicator that measures the percentage of Net New Highs for a particular group of stocks, such as an index or ETF. Net New Highs equals the number of 52-week highs less the number of 52-week lows. High-Low Percent equals Net New Highs divided by the total number of stocks in the group. High-Low Percent fluctuates between -100% and +100%. Chartists can use this indicator to create oscillators and the High-Low Line.

Data Characteristics

StockCharts uses a three-step process to calculate breadth indicators. First, StockCharts maintains component lists for these indices. Second, our scan-engine uses these component lists to run scans based on the price data for the individual stocks. Third, the data is then updated and published to our website. This “in-house” data may differ from other sources due to differences in the index components and price data. Index components change and require updates on a regular basis. Also note that StockCharts uses dividend-adjusted data for its calculations, while other sources may use non-adjusted data.
