This technical indicator guide covers what the accumulative swing index is useful for as a technical indicator for traders.

We use an example chart to show how an accumulative price index may show potential buy or sale signals.

What Is The Accumulative Swing Index?

Developed by Welles Wilder in his popular technical analysis book New Concepts in Technical Trading Systems, the Accumulative Swing Index (ASI) is mainly used as a divergence and confirmation tool, but can be used for buy and sell signals as well.

This chart shows the Accumulative Swing Index for gold futures.

It was designed to be used for futures trading, but can be used for stock trading and currency trading too.

Basically, the Accumulative Swing Index is a running total of the Swing Index.

Accumulative Swing Index as a Confirmation Tool

In the chart shown below, the Accumulative Swing Index confirmed Gold’s downtrend. Subsequently, when Gold broke the downward trendline, the Accumulative Swing Index confirmed the trendline break as well.

Similarly, the upward move in the Gold futures contract was confirmed by the Accumulative Swing Index and the upward trendline break was confirmed too.

Potential Buy Signal – Accumulative Swing Index

A trader might consider a buy signal when the Accumulative Swing Index breaks above a downward trendline or, in a price consolidation period, above resistance.

Potential Sell Signal – Accumulative Swing Index

Contrastly, a trader might consider a sell signal when the Accumulative Swing Index breaks below an upward trendline or, in a price consolidation period, below support.

In summary, the Accumulative Swing Index is best used as a confirmation tool with other technical indicators and charting patterns like support & resistance indicators.
