I hold some stocks, for example, SBI for a few days, and I sold it on one fine day. So now on the same day, I am unable to buy back SBI unless you have an upfront margin. Ok, now what? Can I buy some other stocks apart from SBI? If I bought is that just for intraday or else can I hold them just like I did for SBI before? Here I cannot see any positions and shows 0 and how can I see them now without then and no upfront margin to but another stock.
