In February and March, the stock price rose to a level before it crashed through a window, and the stock price continued to rise to a high price of 9,405 points on May 21. It continues to move above the low support line, and the upward trend continues to form while forming a push. The Bollinger Bands continue to touch the upper band again. In RCI, we can see that the trend has been flat and the upward trend is continuing. As a future strategy, an uptrend is ongoing, so a trend-following strategy would be good. However, there is a possibility that it is forming a rising wedge type chart pattern, so I would like to be careful about grasping the high price.
