What does T1 above the shares I've bought mean?
Indian stock exchanges use the rolling settlement method - Rolling settlement is the process of settling security trades on successive dates so that trades executed today will have a settlement date one business day later than trades executed yesterday. This contrasts with account settlement, in which all trades are settled once in a set period of days, regardless of when the trade took place.
In India, the settlement time for equity is T+2 days, which means if you have purchased shares on a Monday, it will be added to your Demat account by Wednesday evening.
So until then, it will show up in your holdings as T1 quantity i.e. settlement yet to be completed.
