What is the Accumulation/Distribution Line?
The Accumulation/Distribution Line (A/D) is a technical indicator used to identify divergences between price and volume. Developed by Marc Chaikin, it attempts to gauge whether a stock is being accumulated (bought) or distributed (sold), even during periods of price consolidation. Unlike simple volume indicators, the A/D line considers the closing price relative to the price range, providing a more nuanced view of buying and selling pressure. It's categorized under volume indicators in TradingView, offering traders insights into potential trend reversals.
How it Works
The A/D line calculates a running total based on the following formula: A/D = Previous A/D + ((Close - Low) - (High - Close)) * Volume. Essentially, if the price closes near the high of the range, it suggests buying pressure, adding to the A/D line. Conversely, a close near the low indicates selling pressure, subtracting from the line. The A/D line is plotted below the price chart, and its direction reflects the accumulation or distribution of the asset.
Trading Signals
Key signals include divergences. A bullish divergence occurs when the price makes lower lows, but the A/D line makes higher lows, suggesting buying pressure is increasing despite the price decline. A bearish divergence happens when the price makes higher highs, but the A/D line makes lower highs, indicating selling pressure is rising. Breakouts of the A/D line can also confirm price trends. Rising A/D confirms an uptrend, while a falling A/D confirms a downtrend.
Basic Settings
In TradingView, the A/D line has minimal customizable settings. The primary setting is the source data (typically 'Close' price). Some traders experiment with different volume moving averages to smooth the line, but the default settings are generally sufficient. It's best used in conjunction with other indicators and price action analysis for confirmation. This indicator is for educational purposes only, not financial advice.
