Trend bars are “a data visualization tool which represents whether a security or index is bullish, neutral, or bearish.”
Bars can be one of three states:
•Uptrend (atmTB_Up) = green bar
•Downtrend (atmTB_Dn) = red bar
•Neutral = black bar

This study uses conditions for marking bars. To change the display, right-click a bar, then click Select Conditions for Marking Bar.
