Plots move when chart scrolls

[sobertradingpartner]

I've uploaded two screenshots of the same chart. It seems when I scroll the chart, the plot "moves". The plots are created using PlotStyle.Block. The relevant parts of the code are here -

if (State == State.SetDefaults)
...
BlockOffset = 3;
SellBrush = Brushes.Red; // screenshot shows Magenta
BuyBrush = Brushes.Aqua; // screenshot shows Blue

AddPlot(new Stroke(Brushes.Transparent, 6), PlotStyle.Block, "MYTarget");

protected override void OnBarUpdate()
...
PlotBrushes[0][0] = Brushes.Transparent;
// if sell signal
MYTarget[0] = High[0] + (BlockOffset * TickSize);
PlotBrushes[0][0] = SellBrush;
// or if buy signal
MYTarget[0] = Low[0] - (BlockOffset * TickSize);
PlotBrushes[0][0] = BuyBrush;

Can anyone tell me why the plot points are moving higher or lower when the screen is scrolled? I checked if Auto-Scale is the issue and that doesn't seem to be it. Thanks for your time.

Hello sobertradingpartner,

Thank you for your post.

Please right-click your chart and select indicators. Take a screenshot of the indicator properties for this particular indicator with the plot so I may better understand and assist you.

I look forward to your reply.

I took some screens from a different instrument. The same issues are happening there also. The properties are the third graphic. Thanks!

Hello sobertradingpartner,

Thank you for your reply.

I see you have the Scale Justification of the indicator set to "Overlay" which I suspect is causing this behavior. If you change it to "Right" it should share the same scale as the bars which would make it so the plots are adjusted/scaled the same as the bars when you scroll on the chart.

That fixed the issue. Why is it the issue was not resolved when I chose "Left Justification"? Is it just because the main chart is right justified?

Yes, the chart bars have the scale justification set to Right by default. This could also be changed between the options of Right, Left, and Overlay in the Data Series window if desired.

Please don't hesitate to reach out with any additional questions or concerns.
