Before and after the news release, how did the numerical changes of the Williams %R (W%R) indicator in the cryptocurrency market inspire predictions about price trends? Compared with other technical indicators, how accurate is it? Generally, if W%R shows extreme values, it may indicate overbought or oversold conditions. However, in the volatile cryptocurrency market affected by news, its accuracy might be compromised. For instance, sudden news can cause rapid price changes, making W%R less reliable compared to more comprehensive indicators like MACD.
