The advance/decline line (A/D) is a breadth indicator used to show how many stocks are participating in a stock market rally or decline.
When major indexes are rallying, a rising A/D line confirms the uptrend showing strong participation.
If major indexes are rallying and the A/D line is falling, it shows that fewer stocks are participating in the rally which means the index could be nearing the end of its rally.
When major indexes are declining, a falling advance/decline line confirms the downtrend.
If major indexes are declining and the A/D line is rising, fewer stocks are declining over time, which means the index may be near the end of its decline.
Great Indicator, it's linked to nyse advancing and declining indices? Can You include an option for the NASDAQ alternatives? Also, why does the ADL still give a signal outside of market hours? Thanks man
