question about AD Line

Hello I have a question about the Advanec/Decline Line or the Breadth Line Value. In the notes it says it is the #StocksAdvances - #Stocks Decline. In the book it says it is the (#Advances - #Decline) + Previous Breadth Line Value. Please clarify

Hi Anirudh,

Please post CMT questions in the CMT1 forum: https://forum.optuma.com/forum/cmt1-prep-course/

However, the Advance/Decline line is the accumulation of daily advances minus daily declines added to the previous day’s value. So for the S&P500 on October 28th there were 15 advances and 490 declines, resulting in the A/D line falling by 475 (there are actually 505 stocks in the index).
