Red mean down
Black mean neutral
Hope this helped. Take Care
Depends on what software you are using
I always thought the colors represented the market had gone up or down.
Do they actually represent shares bought and sold? The different heights of the candle graphics indicating the volume of people selling and buying at that moment?
I see this video where this guy is day trading stocks and showing the chart saying, okay so green, people are buying shares, oh look, lot of red here, people are bearish they're selling shares I want wait till those lines narrow out then I can bull call this stock, etc.
