Release Notes: - Simplifies the UI to be more instantly apparent of the trend and it's start and end points.
- Simplifies the script down to a simple for loop
- Adds toggle for historical trace lines and prints them as stepline

Apologies to anyone that was using the previous version whose settings will get reset, but I think you'll enjoy this version much better.

TODOs: The trace points currently only work with non-log view -- update the code to check for log view and update the linear-extrapolation algorithm to a logarithmic-extrapolation

This is one of the best script so far :) Thanks bro for this great script. Looks like the error occur when the new bar shows up. Looking forward to see you solve the issue.

@greywolf254, thank you very much. I'm still trying to figure out a work-around for the root cause of the error. My latest guess is that this is a timeout issue caused by the for-loops and the line drawing mechanism being too resource intensive. I'll continue to debug and hopefully TV will optimize the line drawing method.
really awesome script. i tried the other auto trendline apps in the indicators section but they sucked. this one doesnt thank you
Is there anyway to add alerts for when price crosses trendline?
@Lij_MC, not at the moment, but I like the idea. I'll try adding it to a future update!

@Lij_MC, Hey there. I've added plot lines which trace the path the lines take over time which should allow you to add alerts against the current bar. There is still the slight chance that the script will throw a server error and your alert may not fire properly. Apologies in advance -- I'm working with the TV team to try and fix that.
@Lij_MC, So my math is a bit off and the plot points only align with the NON-log view of the chart. This shouldn't cause too many issues if you are looking on a somewhat short timeframe (daily or less), but it's worth pointing out that the plot points you can use to generate alerts may be slightly off the current bar's intersection. Cheers and good luck!

@nickbarcomb, Great thanks will give it a try
Also have "Internal server study error"

@theodorejuliano, yeah, i've been trying several ways to fix it. The error isn't that useful and im still trying to pinpoint the problem. I just hide and unhide to get the indicator back. Thanks for your patience!
