Hello Support, I have a third-party custom study which is not reflecting the change or modification of any colors from subgraphs or input parameters on the chart. I am able to modify the colors and any other values from the input parameters or study subgraphs, and they look correct and valid on the settings. However, they are not reflecting on the chart and all colors on the chart for this study are black (please see attached screen shot). I have tested this thoroughly and even added this study as an only study to a brand-new chart to eliminate any possible conflict or chart corruption. Same problem - I am able to modify colors on the settings and they look correct, but on the chart all colors are still black. I have tested this with Global colors turned ON and OFF - same problem. I am running Sierra v2908 I strongly suspect this issue is local to my installation of Sierra because same chartbook opens without any issues and works correctly on 2 other separate machines for two different users. Could it possibly be a setting on Sierra that affects this? Date Time Of Last Edit: 2026-05-26 04:32:28

From our perspective we do not know the cause of this. Possibly it is an issue related to using OpenGL or not. Sierra Chart Support - Engineering Level Your definitive source for support.

I did not have OpenGL turned on and never used it before. However, after your recommendation I have turned it ON and the chart that was experiencing a problem described above started to work correctly. However, all other charts in the same chartbook that worked correctly before became completely misaligned and even the vertical scale on the right has disappeared. It looks like the entire chart area has been moved to the left and there is a huge empty area added to the right side where the price scale should be. I cannot adjust the chart to bring the main subgraph to the right (see attached screen shot). Now I have the chart that was not working correctly before functioning properly, but all other charts that were good before turning OpenGL ON are messed up. Enabling "Use Compatible OpenGL Profile" did not help either. This can't be a normal behavior. Can you please advise a solution? Date Time Of Last Edit: 2026-05-26 05:37:55

We really do not know what is occurring in your case. Turning on OpenGL should not cause your charts to be different from what they were previously. The only thing we can suggest is to reset your charts back to what you need and then move forward from there. But, if your studies are not working properly, then you would need to talk to the developers to see what may be occurring with the use of OpenGL either On or Off. They would need to deal with that aspect of this. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Hi John, I entirely agree with your point and recommendation in the case if the studies are not working properly (especially third-party). However, in this particular situation there is only ONE aspect of the problem that involves a custom study - the fact that it's not working properly without OpenGL feature turned ON. My understanding is that the only difference between using OpenGL and not using it - is that all calculations and processing of the study are transferred to GPU, instead of the CPU. Is there a C++ compiler option that could affect such behavior and cause the study not to work without OpenGL? I assume this would be the case for all studies compiled for Sierra, not just custom studies. What's more concerning for me is the fact that several charts in the same chart book behave differently with OpenGL feature turned ON and Turned OFF. When OpenGL is flipped back to OFF, other charts return to normal, while others stop working. This is happening even WITHOUT the custom study applied to the chart. It has to be somehow related directly to how the chart is being processed by Sierra with respect to OpenGL feature. I am just trying to get to the bottom of this and avoid such situation as I have a complicated setup and use many charts. As always, your input is greatly appreciated!

Although it has not been as much of an issue as it once was, the support for OpenGL is different between different Graphics Card manufacturers. Nvidia has always had the best support. So if you are not using an Nvidia graphics card, then it is possible that the issues you are seeing are due to this. In which case, you can either change your graphics card (if possible) or just run with OpenGL turned off. As to the custom study that is not working without OpenGL, it is possible that the developer coded specific OpenGL items into what they did, or the opposite. Basically, if they are drawing directly to the graphics, then they are controlling this. If they are using ACSIL to do the drawing, then use of OpenGL or not, is determined based on the setting in the Graphics Settings.

I use 2 video cards in my system - Nvidia GeForce RTX 5060 (8GB) and Nvidia RTX A400 (4GB).

ARe you using a MAC or Linux, and therefore are running Sierra Chart in an emulator? If not the above, then we really do not know why you would have an issue with OpenGL. Our recommendation is to pick one state and adjust everything as needed for that. Then check with the developers of the studies that are not working and see if they have any insight as to why their programs are not working with the OpenGL state you are using.

No, this is Windows 11 Pro system with 96GB or RAM. Thank you, I have turned the OpenGL back to OFF for now until there is a clear understanding of what exactly is affecting the charts in the same chartbook. |

Please get us that chartbook so we can see if we can reproduce the issue. You can attach it privately so no one but Sierra Chart can see it.

Thank you John, I have uploaded the chartbook. There are 2 main charts there - NQ and ES. I have also removed ALL studies from the charts so there is no conflict or any other side effects. When you open the chartbook you will be able to see that when OpenGL are OFF both charts displayed and behave normally. However, when OpenGL is turned ON, the ES chart (on the right) is completely messed up. I am also attaching the screenshots to illustrate this. Thank you so much for looking into this!

This issue may be related to fonts. We want you to update to the current version of Sierra Chart instructions: Software Download: Fast Update Go to the chart where there is a problem when using OpenGL. Set Chart >> Graphics Settings >> Graphics Settings for Chart-Colors >> Settings >> Use Global Graphics Settings Instead of These Settings : No Press OK. Go to Chart >> Graphics Settings >> Graphics Settings for Chart-Fonts Near the bottom press the Reset >> Reset All Fonts To Their Own Default button. Press OK. Save the Chartbook. Restart Sierra Chart. See if the problem is then resolved in the chart. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Hello support, you have (once again) nailed it! I have followed your recommendation (resetting the fonts on the problem chart to their default) and it has fixed the problem. Now when OpenGL is activated the charts are plotted perfectly normal and all studies (including the custom studies) are working as expected and without any issues. Great work and thank you so much for taking your time to identify the root cause of this problem! Quick question: when I have reset the fonts on the chart that was not working, it appears that all fonts for the Sierra has reset also, including data / connectivity statistics window on the Control Bar 1 as well as Open Chart Book dialog window which lists available charts. Is this something that should have happened? I don't have any issue with this just noticed the difference. |

We did test for this issue ahead of time, but not thoroughly. We understand the reason for the problem and it will be resolved in the next release: it appears that all fonts for the Sierra has reset also, including data / connectivity statistics window on the Control Bar 1 as well as Open Chart Book dialog window which lists available charts. Is this something that should have happened? I don't have any issue with this just noticed the difference.
So this is not the expected behavior but it will be resolved. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Excellent. Thank you for the follow up! Meanwhile, I will restore the configuration file to get old fonts and settings back. |
