A GTT, or Good Till Triggered, order lets you set a trigger price and a limit price, and the broker keeps the instruction alive for weeks or months, usually up to a year, until the trigger is hit. Regular exchange orders expire at the end of the day, so GTT solves the problem of waiting for a price without placing a fresh order every morning. Suppose SBI trades at ₹800 and you would like to buy at ₹760. You set a GTT with trigger ₹760 and limit ₹758; when the price touches ₹760, the buy order goes to the exchange. Investors also use GTT as a long-standing stop loss on delivery holdings. Note that a GTT is held by the broker, not the exchange, that execution is not guaranteed after triggering, and that a corporate action such as a split can make the trigger irrelevant.
