Zerodha always frozen during peak times and gap ups, option trading also worst, financial reports is very difficult, ease of login is difficult.
I use upstox, dhan both are good.
Both are free in amc, opening
Difference is Upstox charges Rs20/ order in equity whereas in dhan it is free and ease of web login in upstox is better when compared with dhan.
Reports download for Financial year is very convenient in upstox, dhan need to try but it is also easy when I checked for monthly reports.
DM me or reply me for referral of any app.
