Can I track the thematic performance in the Fyers?

Yes, by the Index value you can easily track your performance of the theme. This Index value is set by default at 100. Your increment and decrement of the theme will be reflected in the Index value and it is calculated on a percentage basis. Let's say if specific plan value goes to 110, then it means that your theme is in profit of 10%. Besides this, you also can track your monthly return & annual return over the thematic investment.
