Description:
This formula is based on Fibonacci And Gann Projections by Dennis Peterson, which appeared in the October 2004 issue of Stocks & Commodities.
Formula Parameters:
* Swing # of Bars - 1
This is the minimum number of bars required to define a swing point. This number is for both sides of the swing point (i.e. 5 bars on the left and right of the swing bar).
* Swing Wave Type - % Change in Price
(% Retracement, % Change in Price)
* Swing Wave Percentage - 5
The number 5 will be treated as 5.0%. The number 0.05 will be treated as 0.0005%.
* Swing High Price Source - Close
* Swing Low Price Source - Close
* Line Thickness - 2
* Confirmed Swing Line Color - Blue
* Developing Swing Line Color - Yellow
* Number of Swings for Gann - 1
The number of previous swings points to be included in the Gann projections
* Gann Increment - 0.25
The +/- increment for Gann calculation above and below the base calculation for Gann.
* Number of Gann Increments - 2
The number of Gann increments to be calculated above and below the Gann basis calculation. 2 will draw one above and one low
the basis.
* Fibonacci: DR 1 - 0.382
* Fibonacci: DR 2 - 1.618
* Fibonacci: A1 1 - 0.5
* Fibonacci: A1 2 - 1.732
* Fibonacci: A2 1 - 0.618
* Fibonacci: A2 2 - 2.0
* Fibonacci: C 1 - 0.707
* Fibonacci: C 2 - 2.618
* Fibonacci: DC 1 - 1.0
* Fibonacci: DC 2 - 3.0
Notes:
The current version has one added modification since the formula went into publication. Per Dennis Peterson's request, a third label has been added to show a second percent retracement figure. The top %Rtmt label is the percent retracement of the developing swing (green Sept peak) to the second previous confirmed swing (blue June peak). The second %Rtmt label is the percent retracement of the right-most developing swing line (current bar) to the previous confirmed swing (Aug valley). The last %Chg label is the percent change in price of the righ-most developing swing line (current bar) from the developing swing (green Sept peak). The related article is copyrighted material.
