Conversely, some traders use RSI to identify potential areas for reversals, so you would look to buy with low RSI values (and vice versa for sell positions).
In the settings, please select which 5 timeframes you require. Then select which tickers you wish to see, and you will find a dashboard on your chart to show the RSI values. The dashboard can be highlighted when the RSI value shows bearish momentum (a value under 50, of your choice) and bullish momentum (a value over 50, again of your choice). These colours and values are fully customisable.
In the settings you can also select the location of the dashboard, as well as some colour and transparency settings to enable the best possible view on screen.
