Good-Till-Triggered Order
A standing instruction held at the broker for up to a year, submitted to the exchange only when its trigger price is reached.
How it is identified
Test: the instruction rests with the broker, not in the exchange order book, until the trigger condition is met

In depth
A GTT order is not in the market — it is a note the broker holds and acts on, which is why it does not occupy a place in price-time priority and cannot be seen by anyone else. That distinction matters when many GTTs cluster at a round number: they all convert at once and hit the book together, producing an air pocket. Because they persist across sessions, GTTs need periodic review; a trigger set for a company whose facts have changed is a stale decision executing itself. Corporate actions can also make an old trigger nonsensical, since the price adjusts but the stored instruction may not.
Worked example
A GTT to buy at ₹400 set today may fire eight months from now. If the company announces a 1:1 bonus in the meantime, the adjusted price halves to around ₹400 for reasons that have nothing to do with the original thesis — and the order fires anyway.
