according to http://www.sierrachart.com/index.php?page=doc/doc_TechnicalStudiesReference.html#s133 ReversalPrice SG3 should be the threshold price at which the swing will change direction. instead it appears to be the end price of the swing, and only populated on the last bar of the swing. please look into this.

SC, please fix ZigZag SG3 Reversal Price also please fix the math here: http://www.sierrachart.com/index.php?page=doc/doc_TechnicalStudiesReference.html#s133 -Mode 1 with Uptrend: ReversalPrice = LastHigh - (LastHigh * Reversal % for Calculation Mode 1) -Mode 3 with Uptrend: ReversalPrice = LastHigh - Reversal Amount for Calculation Mode 2,3 -Mode 1 With Downtrend: ReversalPrice = LastLow + (LastLow * Reversal % for Calculation Mode 1) -Mode 3 With Downtrend: ReversalPrice = LastLow + Reversal Amount for Calculation Mode 2,3 these formulas do not work. as it is now, a user cannot calculate a Method 1 Reversal Price in any way. the study subgraph is incorrect and the math does not work.

SC please tell us the correct way ZigZag calculates the reversal price.

There is some confusion as to what is being conveyed by the study. The study does not currently convey where the current swing will reverse, but instead is conveying ZZ swing points. The spreadsheet output that conveys the reversal price is the same ZZ swing point, not where it would have reversed. To find where a swing might reverse, you use the last swing point and the calculation method to determine the potential reversal point. This reversal point can be changing as the the final swing continues to expand.

please show an example of how to calculate the point at which a swing will "print" and a new opposite direction swing will begin. for EU, the formula above gives irrelevant values e.g. if 1.1010 is the current high and a method 1 reversal coefficient of .06, according to the formula the swing will print at 1.1010 - (1.1010 * .06) = 1.03494 this value is not even close. please explain.

Perhaps you are missing a factor of 100? The input is a percentage, so is divided by 100. For example, an input of 6 translates to 6% which is .06 multiplier. An input of .06 is actually .06% which translates to .0006 multiplier. So, with a high pivot of 1.1010 and an input of .06 you would get: 1.1010 - (1.1010 * .0006) = 1.10033
