I created the 3 Rivers indicator as per the indicator developed by my mentor Mr. Abhijit Paul.The application of this indicator is to gauge the depth of price movement away from the 21 day moving avg . The 3 used are drawn at 3 distinct standard deviations : 1,2,3. These settings can be edited by the user. The interpretation of the indicator is that as the price moves away from the 21 MA into the 1/2/3 stdev zones, the probability of price returning to the 21 MA increases.
