Accumulation Swing Index (ASI)

Category: momentum

The Accumulation Swing Index (ASI) is a cumulative total of the Swing Index, designed to show the 'true' market direction by comparing price relationships between high, low, and close relative to the previous day.

Formula

R = \begin{cases} |H - C_1| - 0.5|L - C_1| + 0.25|C_1 - O_1| & \text{if } |H - C_1| \ge |L - C_1| \text{ and } |H - C_1| \ge |H - L| \\ |L - C_1| - 0.5|H - C_1| + 0.25|C_1 - O_1| & \text{if } |L - C_1| \ge |H - C_1| \text{ and } |L - C_1| \ge |H - L| \\ |H - L| + 0.25|C_1 - O_1| & \text{otherwise} \end{cases} \\ 
K = \max(|H - C_1|, |L - C_1|) \\ 
SI = 50 \cdot \frac{(C - C_1) + 0.5(C - O) + 0.25(C_1 - O_1)}{R} \cdot \frac{K}{T} \\ 
ASI = \sum SI
