Haurlan Index

Haurlan Index

In technical analysis, a measure of market breadth, which is an indicator of the number of advancing stocks relative to the number of declining stocks. The Haurlan Index consists of three parts: a three-day, 20-day and 200-day exponential moving averages of advancing stocks minus declining stocks on the New York Stock Exchange. Each of these is used to look at short-term, medium-term, and long-term trends in market breadth, respectively.
