how to skip a value in AddPlot

[patricia70]

Hello everybody,

I am using AddPlot to draw an indicator into my price chart which I use as a trailing stop-loss. Please ignore the numbers below the bars, they are only for debugging purposes and visible in this screenshot. In the shown example the trailing stop line jumps above the bar because the trend has reversed:



This jump is drawn but I want to skip this part. I have shown it with yellow color in the above screenshot for better visualization. How can I remove/skip this yellow part of my plot? My goal is to have a gap at this bar. The code I use for drawing the line is simply:

[...]
    protected override void OnBarUpdate()
{
if (CurrentBar < 2) return;
{
[...]
if ( trendDir == 1 )
trail = Low[1];
if ( trendDir == -1 )
trail = High[1];
Value[0] = trail;

I tried assigning Value[0] = null; but that doesn't seem to be valid code.

How can I solve this? any help appreciated.
Thanks in advance.

Hello patricia70,
You can do this by changing your plot style from line to dot / block / hash / cross. If you want line then 2 plots will be required & based on your condition you can assign value to the one needed.

Hello patricia70,

Thank you for your post.

If you wish to not plot a value for a particular bar, you can simply just not assign a value to Value[0] for that bar, then on the next bar assign a value. Alternately, if you want values plotted on every bar you could use 2 separate plots, one for the upper and one for the lower line. This example from our help guide shows using multiple plots that you could modify to fit your needs:
