Why are some prices/candles/bars red or blue?
By default in the Trading Station, a price is highlighted with a blue background when it moves up, and red when it moves down.
On the charts, if the closing price of a candle or bar is higher than the opening price, then the candlestick/OHLC bar will be blue. If, instead, the closing price is lower than the opening price, then the candlestick will be red.
