Accumulative Swing Index (ASI)
The Accumulative Swing Index, based on the Swing Index, is a swing or wave system used to capitalize on breakout patterns. ASI is commonly used to confirm trendline breakouts on price charts.
Overview
ASI was developed by Welles Wilder, Jr. as a simple swing system (even though the calculation itself is relatively complex), with signals generated by breakouts past previous highs or lows in the index. Trendlines drawn on the ASI chart are also used to confirm or deny trendline breakouts on a price chart. Any divergence between the Index and price should also be noted.
