Accumulation Distribution Line (ADL)

Overview

Developed by Marc Chaikin, the Accumulation Distribution Line is a volume-based indicator designed to measure the cumulative flow of money into and out of a security. Chaikin originally referred to the indicator as the Cumulative Money Flow Line. As with cumulative indicators, the Accumulation Distribution Line is a running total of each period's Money Flow Volume. First, a multiplier is calculated based on the relationship of the close to the high-low range. Second, the Money Flow Multiplier is multiplied by the period's volume to come up with a Money Flow Volume. A running total of the Money Flow Volume forms the Accumulation Distribution Line. Chartists can use this indicator to affirm a security's underlying trend or anticipate reversals when the indicator diverges from the security price.

Find the mathematical description of the indicator on the Accumulation Distribution Line (ADL) Mathematical Description page.

Adding indicator

ADL indicator is added through the adl() method. It requires a mapping with five fields in it: "open", "high", "low", "close" and "volume".

// create data table on loaded data
var dataTable = anychart.data.table();

// add data to a table
dataTable.addData(get_data());

// map loaded data
var mapping = dataTable.mapAs({"high": 1, "open": 2, "low": 3, "close": 4, "volume": 3});

// create stock chart
chart = anychart.stock();

// create plots on the chart
var plot0 = chart.plot(0);
var plot1 = chart.plot(1);

// create ADL indicator
var adl = plot1.adl(mapping).series();

Note that ADL indicator needs to be built on a separate plot due to rather huge difference between the indicator values and the data values.

Here is a live sample:

It is possible to change the series type any time using the seriesType() method.

Visualization

Visualization of an indicator depends on series type. Here is a sample where ADL indicator is visually adjusted:

// adjust ADL indicator
var adl = plot1.adl(mapping).series();
adl.seriesType("area");
adl.fill("#E5BE01");
adl.stroke(null);
