T means trade day (the day you buy the stock)+ 3 means days for settlement. (Payment)
So If you buy stock as long as you sell it within the three days you do not have to pay for it.
You get to keep the profit or you have to kick in if a loss.
Therefore if there is an anticipated announcement then some traders will buy a swag of stock even though they may not have the full funds. If the announcement comes out or the price goes up on anticipation then great but sometimes the price can fall or not move.
It is a calculated risk!
