I was planning to move all my family accounts with large holdings to Fyers.
I opened account Today for me first and as you are using Trading view I thought It would work here too.
and you do not provide demo prior to account opening I was not able to check. 
I got heavily DISAPPOINTED as I can not put an indicator on other indicator 
I use this https://www.youtube.com/watch?v=Qdug_K_TNHg&t=1050s 

I need to put RSI and WMA and EMA. 
for wma  and EMA source should be the RSI not Close etc.
I am able to do this on Groww, Zerodha etc.

not just me many people follow/use this indicator.
I would not be able to move any of my funds or share holdings until I get this.
Could you please custom build that indicator as soon as possible?
