Bollinger Bands (BOLL): Composed of three track lines, it can show the fluctuation range and trend of the price. When the price touches the upper rail, there may be downward pressure for correction; when the price touches the lower rail, there may be a rebound opportunity.
RSI (Relative Strength Index): It is used to measure the strength of price rises and falls. When the RSI value is below 30, the market may be in an oversold state, which is a buying opportunity; when the RSI value is above 70, the market may be in an overbought state, which is a selling opportunity.
KDJ (Stochastic Oscillator): Composed of three curves, it reflects the price fluctuation by calculating the proportional relationship between the highest price, the lowest price, and the closing price within a certain period. When the K line breaks above the D line, it is a buying opportunity; when the K line breaks below the D line, it is a selling opportunity.
MACD (Moving Average Convergence/Divergence): This indicator helps us judge the trend change and momentum strength of the price. When the fast line (DIF) crosses above the slow line (DEA), it is usually a buy signal; conversely, when the fast line crosses below the slow line, it may be a sell signal.
