The indicator’s fundamental concept is to identify rebounds between support and resistance levels. The indicator has two input parameters: Period and Bars. A support level is the lowest low in the last period bars if this value is equal to the lowest low of the last Period+Bars. A resistance level is the highest high in the last period bars if it is equal to the highest high of the last Period+Bars. If both support and resistance levels exist and a rebound occurs (price is between these levels), then the chart will display both support and resistance levels.
