I am going to share my personal experience with upstox. I have already demate account with zerotha as well as with upstox . Most of time upstox taking time to execute contract . Many time I find my portfolio was disappeared and I am mail to upstox many time tried on call but no response . After 3: 35( after closing) you can easily
Access your portfolio but as you know after 3: 30 u cant purchase sale any script.
Same thing happend with fund and order .
You placed order but application/web is unable to show the same.
Whenever you tried to add/withdrow fund it will take unnecessory time .
So I think this broker must have to upgrade software .
I choose again zerodha .
Reason for choosing zerodha low brokerage charge , very well developed software
And stopped trading throught up stox.
