We updated the documentation to explain the solution. This is an image we added:
https://www.sierrachart.com/images/AdjustRayDrawingForStability.png

We do take exception to saying that they do not work accurately. They are precise and work as designed and Chart Drawings are designed as best as possible. So what exactly is the problem? Mapping into the integer pixel coordinate system of a monitor.

Other programs must have this kind of issue if you have set up the very same kind of line and if you are doing exactly what you are doing in Sierra Chart. And if not, then you are welcome to use another program. We know we are handling this properly and we know the source of this kind of issue. Anyway, it should be resolvable with doing what we said in the image.

Moving trend lines. Almost speechless.
The general answer to this kind of comment from a user is to explain why they should not move. Although that might be hard for you to answer because you do not know all of the things that we know although we try to explain that as much as possible in the documentation.

Also in that video, we can only get a general sense of the problem. It is too overwhelming because it is a video that shows rapid movement and there are a large number of lines in there. We also do not know the anchor points of those lines or the types of drawings they are.


We would actually have to get a Chartbook containing a single line and the instructions to replicate the problem in order to give a precise explanation of it. But in any case, we know in general what the source of this kind of problem is. There is no need to provide a Chartbook.
