Group 1 - The core principle of the article is that in the stock market, declines happen due to inherent weight, while rises require external push to overcome that weight [1] - SSV and RSL are two long-term momentum indicators; SSV measures inherent momentum, while RSL compares inherent momentum with external push [2] - In a long-term downward trend, SSV is sufficient, but once transitioning to an upward phase, both RSL and SSV should resonate upwards [3] Group 2 - The condition SSV>0 AND RSL>0 defines the core logic of long-term trend background [3] - RSL can show positive values even in a downward trend if the decline is slower, which may lead to false signals [7] - During an upward trend, RSL consistently shows negative values for slower gainers, effectively filtering out underperforming stocks [8] Group 3 - Both declines and rises exhibit a Matthew effect; declines accelerate due to inherent weight, while rises require sufficient external push to gain momentum [9] - The article emphasizes the importance of understanding the underlying logic and differences between SSV and RSL, recommending "Laughing at Bulls and Bears" as a foundational text for trend speculation [10]

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) and Relative Strength - The formula for VWAP is defined as SUM(AMO*C,N)/SUM(AMO,N), which represents the average holding cost over a period [2]. - The article introduces a method to calculate relative strength using volume-weighted averages, where deviations from the holding cost indicate the speed of profit or loss, thus reflecting strength changes [1][9]. Group 2: Standardized Strength Algorithms - Two normalization methods are retained for calculating standardized strength values (SSV), with SSV1 defined as (C-VWAP)/VWAP*100 and SSV2 as (C-VWAP)/STDD*100 [2]. - The article also presents a method for calculating RSLine using volume-weighted averages, which appears to be more reasonable than popular moving average methods [5]. Group 3: Momentum Indicators - SSV and RSL are identified as typical momentum indicators that measure current strength and can assess trend reversals through peak and trough divergences, similar to the BIAS indicator [9]. - The update includes the addition of mean outputs for SSV1 and RSL1, while the outputs for SSV2 and RSL2 are hidden [9].
