ZigZag alignment

[Squib]

Hi,

I'm currently about to do my first steps in Ninja Script programming. I started with a modified ZigZag with some different extrema-qualification criterias and used the original ZigZag as a basis.
In general the indicator works fine, but if I attache it to the chart and modify the price scale or if I scroll through the time scale the extremas start to move away from the price. I thought it is a failure of my code, but after checking the original ZigZag I recognized, that this one has the same effect.
Left attachement is the shifted ZigZag line, right one the same indicator, when I scroll a little bit to the future.

Is this a general problem, or is something wrong on my side?

squib,

I am happy to assist you.

Is this indicator applied to a secondary data series? I am unable to replicate this with just a single data series.

What is your scale justification set to? This is located in Indicator > ZigZag > Scale Justification.

Please let me know if I may assist further.

Hi Adam,

thanks for this very fast response. I did not apply the indicator to any secondary data series, just simply to the EURUSD, but I checked my Scale Justification setting. It was "Right". After changing this to "Left" I could not reproduce the effect any more, so this solves my problem.
Could you please explain shortly, what Scale Justification means?

Thanks!

Squib,

I am happy to assist you.

There is a left scale and a right scale. This is typically used for overlaying two data series on one chart and comparing price action, even if the prices are very different. I.e. if you add a second data series to the same chart and set one to left justification and one to right justification, you can then modify each data series scales independently.

Here is a forum link that discusses this : http://www.ninjatrader.com/support/f...ad.php?t=33501

Please let me know if I may assist further.

Perfect!
This explains the effect and I know how to avoid in the future.

Thanks a lot!

changing default setting

Now I have 2 more questions to this topic.

Always if I apply the indicator to the chart, the scale justification is set to "right" by default, so every time I have to manually change this.
Is there a way to set it to "left" by default (maybe within the indicator code)?

And the same question to the "maximum bars look back" setting in the data section of the indicator setting. It's 256 by default. Is there a way to change this to "infinite"? I already tried "ForceMaximumBarsLookBack256=false;" in the indicator-initialization, but this seems to have no influence.

Thanks!

Yes, this is possible. Im going to go ahead and give you links to the help guide since each entry has an example of how to use it.
