"Hello! Sorry to bother you, I would like to ask you a question. Recently, I have been studying the application of the 200-day moving average and found that when the stock price breaks through the 200-day moving average and the trading volume increases, the market trend often continues. However, I am not sure how much the trading volume should increase in order to more accurately determine the effectiveness of the breakthrough. Do you have any suggestions or practical experience to share on this point? Thank you very much for your help!"
