Guess, you got it wrong.
Step 1 - Click on any scrip on your watchlist and open the chart.
Step 2 - If you already have a template, choose that, if not choose your chart preferences (Indicators, drawings etc.) and save the chart layout.
Step 3 - Close that chart and return to your watchlist.
Step 4 - Choose any other scrip and when you load the chart, the same indicator settings and chart preferences will load without having to load the template again. So each time you open a new chart, the same settings will be applied. Previously, that was not possible.
