Calculations
Accumulation Swing Index = CumSum(Swing Index)
Discussion
The Accumulation Swing Index (ASI) is just a cumulative sum of the Swing Index indicator. The accumulation starts with the very first bar loaded (not displayed) on the chart.
Visually the ASI line resembles very much the smoothed price curve itself, however on a different scale. This allows using standard support/resistance analysis, including finding breakouts, divergences, new highs and lows.
NOTE. Since the ASI uses the cumulative sum starting with the very first bar loaded on the chart, it depends on all previous data. If you change the chart’s start date/time, the cumulative sum most certainly changes, and so does the ASI. Therefore, be very careful when using the ASI in a trading strategy because the buy and sell signals depend on previous data loaded on chart.
