This article explains what Accumulative Swing Index is, what signals<\/a> it gives, how it is calculated and set up in a trading terminal, and, naturally, how it is used in trading.<\/p>\n\n\n\n

<\/span><\/a>What Accumulative Swing Index shows<\/span><\/h2>\n\n\n\n

Accumulative Swing Index (ASI) was invented and made popular by a famous trader, financial analyst, and creator of several other indicators<\/a> Wells Wilder. He described the work of ASI in detail in his book New Concepts in Technical Trading Systems, published in 1978.<\/p>\n\n\n\n

For calculating ASI, prices of the current and preceding timeframes are used – Close, Open, High, Low. The results help to assess current price dynamics of the instrument in question. The indicator appears in a separate window under the price chart and looks like one main line.<\/p>\n\n\n\n

The line allows seeing the direction of the current market trend and confirms (or not) breakaways and bounces off the support\/resistance levels<\/a> on the chart. Growing ASI confirms an actual uptrend and falling ASI indicates a downtrend.<\/p>\n\n\n\n

<\/span><\/a>How to calculate Accumulative Swing Index<\/span><\/h2>\n\n\n\n

The indicator is caluculated by the formula:<\/p>\n\n\n\n

ASI(n)<\/strong> = ASI(n-1)<\/strong> + SI(n)<\/strong><\/p>\n\n\n\n

SI(n)<\/strong> = 50<\/strong> * (CLOSE(n-1)<\/strong> - CLOSE(n)<\/strong> + 0.5<\/strong> * (CLOSE(n-1)<\/strong> - OPEN(n-1))<\/strong> + 0.25<\/strong> * (CLOSE(n)<\/strong> - OPEN(n))<\/strong> \/ R)<\/strong> * (K\/T)<\/strong><\/p>\n\n\n\n
