Accumulation Swing Index Calculation from OHLC Data

Summary

Despite a title referring to Bollinger Bands, the body describes the Accumulation Swing Index (ASI). It outlines a calculation using open, high, low, and close prices, comparing the current bar with the previous bar. Intermediate terms measure price changes and gaps; a selected range term is then used to calculate a swing value, which is cumulatively summed to produce ASI.

The document gives indicator pseudocode but does not explain how to interpret ASI, choose its parameters, or turn it into entry and exit rules. It points to a separate file for the indicator’s meaning, but that explanation is not included here. No market, backtest, or performance evidence is supplied, so the material supports understanding the calculation rather than judging its usefulness as a trading signal.

Key ideas

• ASI is calculated from open, high, low, and close data.
• The calculation compares current price movement with prior-bar prices.
• Intermediate range terms determine the scale of each swing value.
• The final indicator is the cumulative sum of the swing values.
• The document provides no interpretation rules or performance evidence.
