But their traffic lights are red, being the traditional "STOP", or caution, etc...why would that be chosen to be applied to something increasing? And apparently chart-decreasing is blue, again opposite correlation to use in traffic lights, meaning "go"

>In Japan, the country where the first emoji sets originated, red is traditionally used to represent increases in the value of a stock. I don't see it necessary to make a correlation to a stop-light's color coding. You could also argue why anything hot is colored red while cool is supposedly blue.

  Well metal becomes red hot, and ice is often blueish in nature. But it is something we humans do, particularly with signaling devices (which a chart is a form of too, arguably) you will see color used in similar fashions to convey a similar meaning. Red is internationally a STOP color, a danger, warning color, and used as such most everywhere; except the Japanese stock market apparently. Which is fine, just curious to me. Another comment here said that in the US some traders flip their colors to indicate red=sell, green=buy, which makes more sense to me in terms of Japan.

    One of the reasons why red is used internationally for stop lights is because it has the least scattering in the air, which means that it can be seen from further away.

The first traffic lights were imported to Japan from the US in 1930, and had "subtitles" written on them because people had a hard time understanding what the colors meant*. Something I find entertaining about the stock colors is that the idioms "in the red" and "in the black" mean the same thing in Japanese as in English. * https://www.pref.hiroshima.lg.jp/uploaded/image/24705.gif https://www.pref.hiroshima.lg.jp/uploaded/image/24705.gif

  Also stop signs were originally yellow, not red, which would add to the confusion.
