The RSI indicator is a powerful tool that utilizes both volume and time to determine market trends. When there is a low volume of trades in a short period of time, but the trading activity is high, it is considered bullish or bearish. In the case of a bullish trend, the RSI indicator will display a green color, while a bearish trend will be represented by a red color. If there is no trading activity, the indicator will display a gray color. Additionally, if the ADX level meets the threshold level, the indicator will display a blue color. However, if the ADX level does not meet the threshold level, the indicator will revert back to displaying a gray color.
