Haurlan Index

The Haurlan Index is an indicator developed by Peter N. Haurlan in the 1960s. It was developed to be an overbought oversold indicator.

This indicator consists of three different components

1. The short term 3 day exponential moving average

2. The Intermediate mediate term 20 day exponential moving average

3. Long term 200 day exponential moving average

All of these components takes the averages from the net advances over declines for the NYSE.

When the short term line (the fast moving line) moves above +100 it is considered a buy signal and remains a buy signal until the line crosses below -150. When the line moves below -150 it is considered a sell signal and remains a sell signal until it crosses above +100.
