ZigZag misbehaving in Strategy

[mntemel]

Hi,

I added the Zigzag indicator into my strategy to find Highs and Lows, code below

ZigZag1 = ZigZag(Close, DeviationType.Percent, 0.05, true);
ZigZag1.Plots[0].Brush = Brushes.DodgerBlue;
AddChartIndicator(ZigZag1);

When i add the zigzag output in my chart I can see it's making unexpected highs and lows, I'm attaching a screenshot. When I use the same settings and add zigzag as an indicator, it's definitely not matching the output from the strategy. Is this something you guys can look at?

Just for context, I use Zigzags barsAgo function to capture past highs and lows in my strategy.

int first_high_barsAgo = ZigZag1.HighBar(0, 1, 999);
int second_high_barsAgo= ZigZag1.HighBar(0, 2, 999);

Is there another method you can suggest to capture past highs and lows since this hasn't worked for me perfectly?

Thanks
M

Hi mntemel,

Thanks for your note.

The code for ZigZag is available to view in the platform under the Indicator folder, studying the High/Lowbar methods could prove useful. What highs and lows do you need for your strategy? From what you posted, you just want the bar number of the most recent occurrence and the second to most recent occurrence of a high bar, is that correct?

I look forward to your reply.

hi Chris,

I'm using the most recent four High and four Low occurrences, and yes all i need is the bar numbers for those occurrences.

thanks

Hello mntemel,

Thanks for your reply.

If you are not getting the output you need from High/LowBar then a custom method would need to be made to target the needed values of Zig Zag. You can open up the ZigZag indicator>Right click>"Save As" then save it under a different name, this will make a copy of ZigZag that you can modify as needed.

Please let me know if I can assist any further.

Hi Chris,

I don't think this is about getting the output I need. I think the problem is the "Use High Low" option of the indicator. If you add this indicator into a blank strategy and plot it (with "Use High Low"=True), and if you add it as an indicator as well, you'll see that they are generating a different outputs. If you False "Use High Low" in both strategy and indicator, then they generate the same output. I think this is a bug.

Thanks

Hello mntemel, thanks for your reply.

I attached a script that will print out the same values as an applied indicator with the same settings, make sure that "Deviation Type" is the same. The default setting for this script is DeviationType.Percent.
