Random Walk Index indicator

Random Walk Index indicator
The following formulas for the random walk index, were constructed using information from the article "Are there continuous cycles" by Michael E. Poulos, in September 1992 TASC.
The formulas for DOS and Windows versions of MetaStock.
All formulas are needed.

Random Walk Index:

Max ((Ref (High, -1) - low) / ((Ref (Sum (ATR (1), 2) -1) / 2) * sqrt (2)), Max ((Ref (High, -2 )-LOW) / ((Ref (Sum (ATR (1), 3) -1) / 3) * sqrt (3)), Max ((Ref (High, -3) - Low) / ((Ref ( sum (ATR (1), 4) -1) / 4) * sqrt (4)), Max ((Ref (High, -4) - Low) / ((Ref (Sum (ATR (1), 5) , -1) / 5) * sqrt (5)), Max ((Ref (High, -5) - Low) / ((Ref (Sum (ATR (1), 6) -1) / 6) * sqrt (6)), Max ((Ref (High, -6)-low) / ((Ref (Sum (ATR (1), 7) -1) / 7) * sqrt (7)), Max ((Ref (high, -7)-low) / ((Ref (Sum (ATR (1), 8) -1) / 8) * sqrt (8)), (Ref (High, -8)-LOW) / ( (Ref (Sum (ATR (1), 9) -1) / 9) * sqrt (9 )))))))))
