The Advance/Decline (A/D) Line is a technical indicator that plots the difference between the number of advancing and declining stocks daily. The formula for the A/D Line is:

A/D = Net Advances + Previous Advances (or subtract if negative)

Net Advances represent the difference between the number of daily advancing stocks and declining stocks. Previous Advances refer to the prior indicator reading.

Example of an Advance/Decline Ratio

To calculate the Advance/Decline Ratio (ADR) for Market Index A:

●    ADR = Advancing Stocks / Declining Stocks 
●    ADR = 200 / 100 
●    ADR = 2.0
 

Interpreting the Advance Decline Ratio

How to Calculate the Advance Decline Ratio Line

Calculating the Advance Decline Ratio Line involves the following steps:

1.    Determine the number of advancing and declining stocks for a specific day.
2.    Calculate the Net Advances by subtracting the number of declining stocks from the number of advancing stocks.
3.    If this is the first time calculating the A/D Line, use the Net Advances as the initial value for the indicator.
4.    On subsequent days, calculate the Net Advances for that day and add the value to the previous day's A/D Line value if the Net Advances are positive. Subtract the Net Advances if they are negative.
5.    Repeat steps 1-4 daily to calculate and update the Advance Decline Ratio Line.
By following these steps, you can track the A/D Line over time and utilise it as a valuable tool in your market analysis.
