What is better TRIN or ADS (Advance/decline sentiment)? http://www.marketvolume.com/technicalanalysis/advancedeclinesentiment.asp Both indicators are based on the number of advance/decline stocks and the volume associated with advancing and declining stocks (see formula in the link above). Basically, both indicator perform the same analysis. 1. TRIN is old and well known - ADS is new 2. TRIN is contrarian indicator - ADS is straight. 3. TRIN oscillates around 1 from 0 to infinity - ADS oscillates around 50 from 0 to 100 4. Since TRIN oscillates to infinity critical levels for NYSE composite, S&P 500 and DJI would be different (different number of stocks) - does not happens with ADS as it moves like Stochastics from 0 to 100. 5. It is difficult mathematically to combine TRIN with other indicators (contrarian and oscillates around 1) - it could be done quite easy with ADS as it moves and it is analyzed as other most popular technical studies.
