Looks like this query has been lingering since Feb 2021. Damn we are about to enter 2024 and the question still remains, When are we getting to view the long term equity curve on zerodha console.
Every feature request in zerodha is a 5 year plan. 
Actually this has been lingering since the original equity curve was launched in April 2019. Zerodha is the first company that i have a love hate relationship with. I am so used to them and their ui and reliability that i can’t go anywhere else but the rate at which they work and deliver features really pisses me off, especially as i grow in my investing/trading journey.
They will literally say “yes, we are working on it” to any random feature request you make and then take 5 years to deliver 1 of them. But then we don’t have many other choices either. I hope Groww and Dhan to some magic and bring them back on their toes.
From 2019
