Advance/Decline Ratio History Calculator


Trading System based on the "advances" and "declines" concept

The Advance/Decline (A/D) issues and A/D volume ratios are among the most popular sentiment indicators. They are used by technical analysts to anticipate potential market reversal points. Extremely low A/D issues and A/D volume ratios are indicative of an extremely bearish market sentiment, thus allowing market observers to anticipate potential bullish market reversals. Conversely, highly elevated readings of the A/D issues and A/D volume ratios may indicate an overly bullish sentiment, often pointing to a potential downside reversal.

Our research has uncovered incidences where the Advance/Decline issues and Advance/Decline volume ratios were either critically elevated or extremely low. This data can now be used to define index levels thought to be critical for an upcoming trend reversal. A database has been established that allows traders to devise their own trading strategies (Click HERE to see an example of a mid-term trading system built on the premise of critically low A/D issues and A/D volume ratios for the S&P 500 index).
