Custom Render Disappearing

[Vikuno1]

Hello All,

I have developed an indicator that uses a custom rendering. I am using values from another time frame and it works flawlessly when I load it onto a historical chart.

For some reason the moment the state turns to realtime it disappears completely.

No errors in the log, I also setup print statements to make sure the entire function was running and it runs all the way through everytime.

Let me know if I am missing something.

You can recreate by opening up a 15 Second and loading it.

Thanks

Hello Vikuno1,

I've tested the script on a 15 second ES 09-24 chart without connecting, and I am not seeing anything rendered in historical, and connected and I am not seeing anything rendered in real-time.

"I also setup print statements to make sure the entire function was running and it runs all the way through everytime."

Are you printing the ChartPanel.Y and ChartPanel.Height + ChartPanel.Y as well as the ChartPanel.W and print the x and y coordinates of the objects you are rendering to ensure these are in the rendered area?

Print(string.Format("ChartPanel.W: {0}, startX: {1}, ChartPanel.Y: {2}, chartScale.H + ChartPanel.Y: {3}, startY: {3}", ChartPanel.W, startX, ChartPanel.Y, ChartPanel.H + ChartPanel.Y, startY));

May I have the output from the prints?

It renders in front of the most recent bar always.


you are looking at the most recent bar and there is nothing to the right?

Hello Vikuno1,

I'm not seeing anything rendered on the most recent bar or to the right of it.

Here is the print as well as a picture of the render.

ChartPanel.W: 1059, startX: 832, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783
ChartPanel.W: 1059, startX: 873, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783
ChartPanel.W: 1059, startX: 914, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783
ChartPanel.W: 1059, startX: 955, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783
ChartPanel.W: 1059, startX: 996, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783
ChartPanel.W: 1059, startX: 1037, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 783, startY: 783

Trying disconnecting to data so that the chart is frozen and then adding the indicator

Hello Vikuno1,

The connection was not connected when I added the indicator.

I am seeing that your startY value is out of the viewable area.

startY: 783 this needs to be several pixels less than chartScale.H + ChartPanel.Y: 783 to be in the viewable area.

The viewable area stops at 783.

Hey Chelsea, thank you for you speedy response.

There was actually a mistake in the print statement you gave.
"Print(string.Format("ChartPanel.W: {0}, startX: {1}, ChartPanel.Y: {2}, chartScale.H + ChartPanel.Y: {3}, startY: {3}", ChartPanel.W, startX, ChartPanel.Y, ChartPanel.H + ChartPanel.Y, startY));"
You used the 3rd string twice instead of using {4}

Here is the updated Print Statement:
ChartPanel.W: 1273, startX: 555, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 378
ChartPanel.W: 1273, startX: 572, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 529
ChartPanel.W: 1273, startX: 589, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 546
ChartPanel.W: 1273, startX: 606, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 557
ChartPanel.W: 1273, startX: 623, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 579
ChartPanel.W: 1273, startX: 640, ChartPanel.Y: 0, chartScale.H + ChartPanel.Y: 801, startY: 467

Also the part I circled in Red is the actual rendering not the candles from the chart

Thanks!

Hello Vikuno1,

Oh, good catch!

"Also the part I circled in Red is the actual rendering not the candles from the chart"

I'm not clear I'm understanding. I'm not seeing anything in the circled part of the screenshot.

Sorry in this picture I am uploaded you don't see anything circled in red?

Hello Vikuno1,

All I am able to see are the chart bars on the chart.
Within the red circle I am seeing a red chart bar, followed by 4 more red chart bars, and then a green chart bar.
I also see the horizontal crosshair line.

Perfect! Everything inside of the red circle is a rendering that I have created. When the indicator is run in real time or on playback it disappears. This is what I am trying to solve. I am attaching the mock indicator again as well. Let me know if I am missing anything!

Hello Vikuno1,

I'm not certain I am understanding.

Are you saying you are rendering the candles I am seeing on the chart and that the chart bars have been set to transparent in the Data Series window?
(Meaning all of the candles are rendered by the script and none of the chart bars are showing, correct?)

If not, how are you able to tell what is rendered by your script and what is being rendered by the ChartStyle?
(If you had chosen purple or a different color, this would make your custom rendering stand out)

Thank you for your speedy responses! Here is an updated copy that changes the color and I changed the color so the rendering pops

Hello Vikuno1,

Thank you for the modification.

I can clearly see the purple and aqua rectangles are not the chart bars rendered by the ChartStyle now.

Testing on my end, I see now that you have to move the horizontal time scale range to see the rendered objects.

However, in real-time I am still seeing the rendered rectangles. I'm not sure I am understanding what the issue is.

Below is a link to a video of the test.

Is the issue that without adjusting the time scale range to the right of the chart bars the rectangles are not in the viewable area?

Hey Chelsea! Thanks for the video. For some reason this weekend when I was testing as soon as the chart would start receiving data the render would disappear completely. I just tested it on my end again and for some reason now it is working flawlessly. A mystery for sure. I'll let you know if anything else breaks, sorry for the waste
