What is Alert Triggers Orders (ATO)?

Alert Triggers Orders (ATO) is a feature that automatically places a linked basket of orders on the exchange when your Kite alert is triggered. In ATO, market orders are placed with market price protection.

For instance, if you want to buy a NIFTY 100 ETF, like Zerodha's TOP100CASE, when the NIFTY 100 index drops by 10% or more, you can use ATO to set an alert and automatically place a buy order for TOP100CASE. When the index falls by 10%, your alert will be triggered, and a buy order for the TOP100CASE ETF will be automatically placed.

You can also create alerts or ATOs for a particular instrument by visiting kite.zerodha.com/orders/alerts and then clicking on New alert.


You can change the order type, whether buy or sell, without opening the order window by clicking on B (Buy) or S (Sell). You can delete multiple instruments by selecting the box next to the instrument name or by selecting the box beside Type and clicking on Delete to remove all instruments from the basket.

You can edit the quantity and price without opening the order window by clicking on the up or down arrows or manually entering the values.


The Alerts section displays all your alerts, whether enabled or disabled. The types of alerts are displayed as SIMPLE or ATO, and you can modify, enable, disable, or delete them at any point until they are triggered from the Alerts section. Kite alerts have a validity period of 365 days and will be automatically disabled after this period unless triggered or manually disabled earlier.

Your alerts will be disabled automatically if there is a corporate action for the instrument that changes the price by more than 2%, such as extraordinary dividends, bonuses, splits, or rights issues.

You can delete, duplicate, or edit individual instruments by clicking on the options icon. Additionally, you can change the order sequence by dragging and dropping. The margin required will be different based on the sequence of individual orders, while the margin blocked after execution remains the same.

To include open positions that are not part of your basket and verify margin requirements, select the Include existing positions option. However, this option may display a required margin of 0, even when you need margin to place the order. This happens because an order in your basket might reduce the overall margin requirement while still requiring margin for placement.

For F&O strategies, place buy option orders before future or short/writing option orders. This approach executes your F&O strategy with the least margin requirement, as displayed below:

By default, your orders have a Day validity and are cancelled if not executed by the end of the trading day. You can change this validity from the order window.

Email alerts: You will receive push and email notifications upon the triggering and execution of an ATO. Once an ATO is triggered and your order is placed, you can check its status via email or the Alerts section.


You can identify ATOs on the order history page by the bell icon.


ATO is not available for currency and commodity segments.
