I have seen something on this in the past but can't seem to find it. Is there anyway to avoid charting seemingly randomly deciding not to draw lines? I have custom indicators I have written using Drawline to draw lines at calculated levels.
Usually this works but at times, it simply doesn't draw the line until some future point at which time, it draws it completely correctly (start to end, that isn't the issue). I have other indicators that use the actual number and it is correct so that is definitely not the issue (so that isn't the issue either).
Sometimes scrolling one direction or the other causes it to draw but usually it just suddenly reappears. To say this is annoying is an understatement but worse yet, I trade live based on this information.
At times I don't realize the number that should have been drawn wasn't (it can be difficult to prove a negative). I could check the other indicators and work backwards but this seems like a pretty serious bug for someone who trades live.
