The indicator identifies and marks the WRB - very long bars (Wide Range Bars) or candlesticks with long bodies (Wide Range Bodies). Since WRB-bars themselves do not represent the values of the indicator also identifies hidden gaps based on these bars. It shows in different ways filled and unfilled hidden gaps, so that only by looking at the screen, it is possible to very simply determine the current situation. Also, you can turn on the notification of the current price entry into the unfilled gap zone.
