I have no POA.
I usually trade currency futures & MCX silvermicro & goldguinea/Goldpetal futres. no problem, I place orders usually In NRML (not MIS ) & I carry forward positions to next day also.
If I do trade stocks (only intraday & never CNC) it is only under MIS . Sytem will close out position by 3.20pm, (atleast saving grace is no ₹50+ gst like Zerodha)
