ZigZag deviation type

[binwang2]

Hello, NT experts,

The ZigZag deviation type has 2 options: points and percentage. I would like to know the exact definitions of points and percentage.

Now I assume the following: if the prior ZigZag is a swing high, then the percentage is the (ZigZag_Immediate_prior_HighBar_price - current_price)/ZigZag_Immediate_prior_HighBar_price. If this percentage is greater than the input value, then ZigZag is ready to find the next ZigZag low.

Let me know if that makes sense.

binwang2,

The DeviationTypes are used when determining if you are over the high/low deviations. That information is then used to determine whether or not to set a new high/low or not.

bool isOverHighDeviation = (deviationType == DeviationType.Percent && IsPriceGreater(highSeries[1], (lastSwingPrice * (1.0 + deviationValue * 0.01))))
|| (deviationType == DeviationType.Points && IsPriceGreater(highSeries[1], lastSwingPrice + deviationValue));
