Accumulative Swing Index

The accumulation swing index (ASI) is a variation of Welles Wilder's swing index. It plots a running total of the swing index value of each bar. The swing index is a value from 0 to 100 for an up bar and 0 to -100 for a down bar. The swing index is calculated by using the current bar's open, high, low and close, as well as the previous bar's open and close. The swing index is a popular tool in the futures market.

The accumulative swing index is used to gain a better long-term picture than using the plain swing index, which uses data from only two bars. If the long-term trend is up, the accumulative swing index is a positive value. Conversely, if the long-term trend is down, the accumulative swing index is a negative value. If the long-term trend is sideways (non-trending), the accumulative swing index fluctuates between positive and negative values. This indicator is used to analyze futures but can be applied to stocks as well.
