Random article: Accumulation Swing Index
In his book “New concepts in technical trading systems” Wilder says: “If ASI lays on the same day chart, comparison with chart's lines can be made along the tendency shown by the indicator. For someone, who knows how to draw meaning trend's line, this indicator can serve as a nice tool confirming lines breaking the trend. Wrong break ups will not be confirmed by relevant lines in the indicator's area. Since to a greater extent ASI uses Close prices, intraday up and down movements do not influence indicator's index value heavily.”
