Core Viewpoint - The article discusses the construction of a true cost price curve using cumulative transaction amount divided by cumulative transaction volume, emphasizing its accuracy compared to traditional methods [1]. Group 1: Volume-Weighted Average Price (VWAP) - The article introduces a new formula for calculating VWAP using cumulative transaction amount (AMO) and price (C), which is expressed as SUM(AMO*C,N)/SUM(AMO,N) [1]. - This VWAP formula is designed to be more sensitive and reliable than traditional volume-weighted methods, especially when accounting for stock splits and other corporate actions [1]. Group 2: Standardized Strength Calculation - A new standardized strength formula is proposed, replacing the arithmetic mean price with the volume-weighted price, resulting in VWAP and standard deviation (STDD) calculations [1]. - Two output methods are provided: one using the weighted price as the divisor for deviation and another using standard deviation for normalization [1]. Group 3: Relative Strength (RS) Calculation - The article extends the VWAP concept to calculate a relative strength line (RSLine), which is claimed to be more reasonable than popular moving average methods [4]. - The RS calculation is defined as CLOSE/INDEXC, with a volume-weighted RS (VWRS) formula introduced for enhanced accuracy [4]. Group 4: Output Comparison - The article notes that the output from the new calculations is consistent and stable when configured as a Relative Strength Ratio (RSR) [2]. - It highlights the effectiveness of using volume-weighted prices in producing reliable output compared to traditional methods [2].
