Hi,
How do I save a chart settings that would apply for all instruments.
Whenever I open new chart it is defaulting to line. I was expecting it save last used settings., if not something defined by me.
If using the desktop platform;
Open a chart, set it up (add indicators, change views etc.) then right click on to the chart, scroll down to ‘Templates’ select ‘Create Template’ name it, save it and then when previewing a new instrument, right click on it immediately and then scroll down to ‘Templates’, select the one you created and it will open up as you’ve previously defined.
this is no longer possible
Hello there and welcome to the Community 
The web app was recently updated, and it includes an improved TradingView integration. After the update, there’s no ‘Save layout’ button. Instead, each drawing and indicator you apply to the chart is automatically saved. Still, I see how it can be useful to save specific templates and I’ll forward your feedback.
