Key facts

When a GTT is rejected	Most often at trigger time, not placement; the released limit order is validated against funds, freeze limits, and instrument status when it fires
Top rejection causes	Insufficient funds or holdings, freeze-quantity breach, ineligible or blocked scrip, contract expiry, and quantity or symbol changes
Order type released	A single limit order; a gap past the limit leaves it unfilled, which is a non-fill, not a rejection
Active-GTT cap	Up to 500 active GTTs per account
Guarantee	GTT is best-effort: stored on Zerodha's servers, fired once, and dependent on funds and eligibility at trigger time

A GTT (Good Till Triggered) order on Zerodha Kite is a broker-stored conditional instruction that releases a single regular limit order to the exchange when your trigger price is touched, and it is rejected when that released order fails validation, most often for insufficient funds, a freeze-quantity breach, an ineligible or blocked scrip, or an expired contract; because the GTT is not lodged at the exchange and fires only once, it is best-effort rather than guaranteed. The distinction that trips up traders is that a GTT can pass placement-time checks today and still be rejected at trigger time months later, when the funds, eligibility, and exchange limits are re-evaluated. This article documents the instrument-eligibility, quantity, funds, and structural limits, the specific rejection messages, and the reason a GTT should be treated as a convenience layer, not a certainty.

The GTT reference article covers the product, GTT validity rules on Kite covers the expiry window, and why a GTT triggered but did not execute covers the non-fill case specifically. This page is the limitations-and-rejection companion.

Rejection at trigger time, not placement time

The most important structural fact is that a GTT is validated twice, and the two checks are separate. At placement, Zerodha accepts the GTT with light validation: it does not check whether you have the funds for a buy or the shares for a sell, and it stores the order on its servers. The hard validation happens at trigger time, when the GTT fires and the released limit order is submitted to the exchange. That released order is checked against your live funds, the exchange’s current freeze limit, the scrip’s trading status, and the contract’s validity, and any failure there produces a rejection.

This is why a GTT accepted in January can be rejected in June. The conditions that matter, your account balance, the scrip’s surveillance status, the contract’s existence, the exchange freeze quantity, are evaluated when the order fires, not when you set it up. A trader who placed a buy GTT and later spent the cash on other trades will see the GTT trigger and the released buy limit order rejected for RMS reasons, with the GTT marked triggered but no position taken.

Funds and holdings at trigger time

A buy GTT needs sufficient funds when it fires; a sell GTT needs the shares in the demat or the open position. Zerodha does not reserve funds at placement, so a buy GTT does not block the cash, and a trader who depletes the balance before the trigger gets a rejection on the released order. The fix is to maintain a buffer covering pending buy GTTs, or to set an alert so funds are topped up before a near-trigger GTT can fire.

A sell GTT carries the mirror risk. If you sold part of the holding after setting a sell GTT for the full quantity, the triggered sell can exceed the shares you still hold, producing a short-delivery situation or a rejection, depending on the shortfall. The discipline is to modify or cancel the GTT whenever you change the underlying position, covered in how to modify a GTT on Kite , so the GTT quantity always matches what you hold.

Instrument eligibility

GTT is not available on every instrument, and a GTT placed on an ineligible one is rejected when it triggers even though placement accepted it. The eligible set is equity cash on the NSE and BSE , and equity and index F&O, on the MTF, CNC , and NRML product types. GTT is not offered on the currency segment. A GTT on a contract Zerodha does not allow for trading at the moment it fires is rejected at that point.

Surveillance and trading-status changes are a frequent eligibility trap. A scrip that was freely tradable when you set the GTT can move into a blocked or restricted list, ASM , GSM , trade-to-trade , or a Zerodha-imposed block, by the time the trigger fires, at which point the released order is rejected. GTTs are also cancelled outright when the underlying changes materially: an equity F&O GTT is cancelled if a corporate action affects the lot size or price, and an index F&O GTT is cancelled whenever the contract’s lot size changes. The complete disabled-and-cancelled taxonomy is in GTT disabled, cancelled, or expired .

Quantity and freeze limits

The released order must respect the exchange’s freeze quantity, the maximum quantity allowed in a single order for an instrument, set by the exchange and revised periodically, especially on derivatives. A GTT whose quantity exceeds the freeze limit at trigger time produces a freeze-quantity rejection on the released order, the same limit documented in how to fix a freeze-quantity rejection . Because the freeze limit can change between placement and trigger, a GTT sized at the limit when set can breach a tightened limit later.

The other quantity constraint is OCO consistency. In an OCO (One Cancels Other) GTT, both legs carry the same quantity because they refer to the same position. If the position size changes after the OCO is set, the surviving leg can fire for a quantity that no longer matches the holding, the sell-side mismatch described above. Equity GTTs are also not auto-adjusted for corporate actions: a sell GTT at Rs 200 on a stock that does a 2:1 split fires at Rs 200 post-split, which is effectively double the intended target, so trigger levels must be reviewed and reset after any split, bonus, or rights issue.

Single vs OCO and the 500-order cap

A GTT is either a single-trigger order, one condition firing one limit order, or an OCO, two conditions where one firing cancels the other. The single-trigger form is the building block for a buy-on-dip or a one-sided stop; the OCO form protects a held position on both sides at once, a target above and a stop below, with the unfired leg auto-cancelled when one fires. An OCO does not place both orders; it places the leg whose condition is met and cancels the other, so both a target and a stop cannot execute from one OCO.

An account can hold up to 500 active GTTs. Each single-trigger GTT and each OCO counts as one slot, so an OCO is the slot-efficient way to get two-sided protection. At the 500 ceiling, new GTTs are refused until existing ones expire, trigger, or are deleted, so a trader running individual stops across a large book should delete GTTs on closed positions to free slots, covered in how to delete a GTT on Kite .

Rejection versus non-fill

A rejection and a non-fill are different failures with the same outcome of no trade, and separating them is the key to diagnosing a GTT that did not work.

Outcome	What happened	Typical cause
Rejected	The released order failed validation and never reached the order book	Insufficient funds or holdings, freeze breach, ineligible or blocked scrip, expired contract
Triggered, unfilled	The order reached the exchange as a limit order but did not execute	The market gapped past your limit price; no counterparty at your limit
Not triggered	The trigger price was never touched during market hours	Price did not reach the trigger; GTT later expired

A rejection means the order failed a check. A non-fill, by contrast, means the limit order was accepted by the exchange but rests unexecuted because the market moved past your limit, the gap case detailed in why a GTT triggered but did not execute . Both leave the trader without the position, but the remedies differ: a rejection needs the underlying cause fixed (add funds, check eligibility, resize) before re-placing; a non-fill needs a closer limit, or an SL-M order in place of the GTT for a guaranteed market exit.

Why GTT is best-effort, not guaranteed

GTT is a broker-level facility, not an exchange-recognised order type. It sits on Zerodha’s servers, and the exchange sees nothing until the trigger fires and a limit order is submitted. Three properties make it best-effort rather than guaranteed. It depends on Zerodha’s server firing the order when the trigger is touched, so a broker-side outage can prevent it from firing even when the market reaches the trigger; a resting exchange order does not carry that dependency. It fires once and does not re-arm, so a triggered-but-unfilled GTT must be re-placed manually for the next session. And it releases a limit order, never a market order, so it will not chase the price past your limit.

These are not defects to be fixed but the design of a server-stored conditional facility, and SEBI’s intermediary-disclosure rules require brokers to make the risk of such conditional-order services clear to clients. The practical consequence for a trader is that a GTT is a convenience that removes the daily re-entry burden of a session-bound order, not a substitute for an exchange-resident order on a position that cannot be left to a single best-effort trigger. For a guaranteed intraday exit, an SL-M at the exchange is the right tool; for a long-horizon buy target or a multi-day backstop, the GTT’s persistence is worth its non-fill tail risk. The validity windows that govern how long each GTT survives are in GTT validity rules on Kite .

Frequently asked questions

Why was my GTT order rejected on Zerodha?

A GTT is usually rejected at trigger time, when the released limit order is checked. The common causes are insufficient funds or holdings, a quantity above the exchange freeze limit, an ineligible or blocked scrip, a delisted or expired contract, or a symbol or lot-size change since you placed the GTT.

Is a GTT order guaranteed to execute?

No. A GTT is best-effort. It sits on Zerodha’s servers, fires once when the trigger is touched, and releases a single limit order that the exchange may reject or leave unfilled. It is not lodged at the exchange and carries broker-server dependency that a resting exchange order does not.

What is the difference between a GTT being rejected and not filling?

A rejection means the released order failed validation, for missing funds, a freeze breach, or an ineligible scrip, and never reached the order book. A non-fill means the order reached the exchange as a limit order but the market moved past your limit price, so it rests unexecuted. Both leave you without the trade.

Can a GTT be rejected even though it was accepted when I placed it?

Yes. Placement-time validation and trigger-time validation are separate. A GTT accepted today can be rejected when it fires months later because funds are short, the scrip moved into a blocked surveillance list, the contract expired, or the exchange freeze quantity changed in the interim.

How many GTTs can I keep active, and does OCO count as one?

An account can hold up to 500 active GTTs. Each single-trigger GTT and each OCO (One Cancels Other) GTT counts as one slot, so an OCO that protects both a target and a stop uses a single slot against the 500 cap.

What happens to a GTT after a corporate action or lot-size change?

GTTs are not auto-adjusted for equity corporate actions, so a split or bonus can leave the trigger at a stale price; review and reset it. For F&O, a GTT is cancelled if a corporate action affects the lot size or price, and an index F&O GTT is cancelled whenever the lot size changes.
