Stock Trends symbols and indicator values are used to quickly and visually communicate the results of our moving average trend analysis.
Volume Indicator Symbols
Stock Trends uses two volume indicator symbols to identify stocks that have traded an ‘unusual’ number of shares during the week. The term ‘unusual’ is arbitrarily defined as >= 200% (i.e. double) or <= 50% (one-half) of the 13-week average weekly trading volume for a stock. Since infrequently traded stocks would tend to trigger these indicators more often than not (too often to be useful), the volume indicators are limited to stocks with a minimum average weekly volume of 100,000 shares traded.
Unusually high volume indicator
The stock’s trading volume for the week is at least double (>= 200%) its average weekly volume (13-week moving average). Trading implications: The High Volume 
indicator, concurrent with a Bullish Crossover 
symbol, has proven to be a highly successful identifier of stocks verging on a long-term bullish trend. Generally, high volume should support price advances, and at times can precede or anticipate them.
Unusually low volume indicator
The stock’s trading volume for the week is no more than one-half (<= 50%) its average weekly volume (13-week moving average). Trading implications: The Low Volume 
indicator, concurrent with advancing price, offers both a warning for Bullish ( 
or 
) stocks and a possible Buy trading signal for Bearish (
or 
) stocks.
