WR index is a technical analysis index, which measures the strength of market trading power by calculating the ratio of stock price rise and fall over a period of time. WR index generally adopts the critical value of period 14 days or 10 days, overbought and oversold. These settings can be adjusted according to the actual situation. WR index can help investors to judge the trend and inflection point of the market, and it is one of the commonly used technical analysis tools.

WR index is helpful to understand the trading situation of the market, but it is not an absolute forecasting tool. In the actual operation process, investors need to comprehensively analyze other indicators and fundamental factors to decide whether to conduct trading operations. At the same time, the application of WR index also needs to form its own personalized strategies and methods, because investors have different trading preferences and risk tolerance.

WR index can help investors catch market fluctuations and reversals in the short term, but it may not be suitable for long-term trading strategies. In addition, WR index also has some limitations. For example, under unilateral and fluctuating market conditions, WR index may be noisy and misjudged. Therefore, when using WR indicators, investors should also consider the overall market situation and the characteristics of individual stocks in order to formulate appropriate investment strategies.
