Accumulation Swing Index
The Accumulation Swing Index is a running total of the Swing Index. The Swing Index is calculated using only the two most recent bars, by summing it, the Accumulation Swing Index shows long-term trends. It will be positive in a long-term up trend, negative in a long-term down trend and it will hover around zero if the market is flat. The shape of the Accumulation Swing Index line closely matches the shape of the price line. It can be interpreted by comparing it to the price and looking for divergence or confirmation.
The Accumulation Swing Index was developed by J. Welles Wilder and is described in his 1978 book New Concepts In Technical Trading Systems.
