Accumulation Swing Index

The Accumulation Swing Index is a cumulative total of the Swing Index. The Accumulation Swing Index was developed by Welles Wilder. Wilder noted the following characteristics of the Accumulation Swing Index:

• It provides a numerical value that quantifies price swings.
• It defines short-term swing points.
• It cuts through the maze of high, low, and close prices and indicates the real strength and direction of the market.

The Accumulation Swing Index is a cumulative total of the Swing Index. The Swing Index and the Accumulation Swing Index require opening prices.

The Accumulation Swing Index attempts to show the “real market” because it closely resembles prices themselves. The ASI attempts to provide an indication of the real strength and direction of a price trend by providing a single indicator line which can be analyzed for support and resistance lines just like a basic price chart. If the long-term price trend is up, the ASI will be positive. If the long-term price trend is down, the ASI will be negative. If the long-term price trend is oscillatory, the ASI will fluctuate from plus to minus. A typical analysis involves looking for breakouts, new highs and lows, and divergences.
