Way to keep trend lines when switching between symbols?

[bosslife]

when i create trend lines for example on eurusd, change to eurcad, and then back to eurusd the trend lines are gone. i know i could save it as a template or profile but thats way too time consuming (including creating a profile for each currency and switching between them).

is there any way to make the re-appear automatically when switching between symbols?

1. You have code that is removing them. Fix your broken code.
2. What would a trendline on one symbol have any value on another?
