Is there a way to lock the custom fibonacci settings, so that the same custom settings appear on every chart? Really cumbersome to set them manually on every chart. 
Save it as a view and apply it on charts you analyse.
It does not work when you pop out the chart even when I save it as a view.
Drawing tool settings are saved only stock wise. You cannot apply the same setting for all stocks.
So if you select the Fibonacci retracement tool, select all percentages in settings and apply it to a stock chart, it will be saved specifically to that stock chart only. And all your selected percentage settings will show on that chart.
But if you are adding the Fibonacci retracement tool to another chart, then you will have to select your desired settings again. This is probably how the drawing tools are designed on Kite.
@Sanket, drawing tools are saved in the browser cache and views are saved on the cloud server, which is why when you clear your browser cache, your drawings get deleted but the views remain.
