Just call us Bond. Amortized bond.
Over 700 finance terms, Shmooped to perfection.
The T here refers to time, and the 3 refers to 3 days.
So T+3 = the 3-day time period that you have to wait after you buy or sell a stock. Yep, it takes three days from when your order is executed until you actually have the stock or the money in your hot little hands.
