This is an indicator that gives you a visual indication that you are currently oversold. We mainly use ROI to determine if the market is currently oversold. I made it so that you can easily visually judge from the chart what is difficult to check visually, such as checking the ROI value normally. The background color can be changed freely. You can also set alerts to receive alerts the moment they are oversold. I think that it will help you to detect the timing of a momentary plunge with a short foot of about 5 minutes or 10 minutes.
