Interpretation

Tradingview

Upward Trend: During an uptrend you will see the ADL trending upward, which is a suggestion that a large number of stocks are participating in the rally (market), indicating market strength.

Downward Trend: This is the opposite of the upward trend, in which you will see the ADL signals that a large number of stocks are declining rather than advancing, which is an indication of the weakness of the market.

Divergence: This is when the ADL moves in the opposite direction of a major market index, which can signal a potential market reversal. In a situation where you see that the index is rising but the ADL is falling, it means that fewer stocks are supporting the market, which may lead the market to a downward movement.

Calculation

The given formula is used to calculate the ADL indicator.

Advance decline line = Advancing stocks - Declining stocks + Previous Net Advance

We have the daily calculation which is calculated by misusing the advance stocks from the decline stocks. Let's consider looking at the given example below.

Let's say as an investor you are looking for a way to create an ADL for an index for over four days and you are been given the following data as shown below.

ADL	DAY 1	DAY 2	DAY 3	DAY 4
Advancing stocks	70	60	56	40
Declining stocks	30	40	40	60
Total Stocks	100	100	100	100

Based on the information above, the calculation will be as shown below.

ADL Day 1 = 70 – 30 + 0 = 40

ADL Day 2 = 60 – 40 + 40 = 60

ADL Day 3 = 56 – 44 + 60 = 72

ADL Day 4 = 40 – 60 + 72 = 92
