TASC = Technical Analysis of Stocks & Commodities
TradeStation: November 2023
In his article in the September 2023 issue titled “VAcc: A Momentum Indicator Based On Velocity And Acceleration,” author Scott Cong has introduced a new momentum indicator based on the simple physics principles of velocity and acceleration. The indicator is said to be responsive, precise, and easy to use. In addition, the indicator is said to be less susceptible to overbought/oversold saturation. The TradeStation implementation in EasyLangauge uses a VAcc function.
