The Range Indicator by Jack Weinberg for ThinkorSwim


Staff member
Developed by Jack Weinberg, Range indicator compares intraday range with inter-day range. Author had a strong belief that crossing of intraday range outside the inter-day range is an indication of end of current trend

  • RI crossing above level 80 is a signal to exit
  • RI below 20 is indication that a new trend is about to take charge
  • RI is useful to filter signal given by other studies
It oscillates between 0 to 100 levels
