Key facts

Corporate-action disable	Kite auto-disables an alert when a corporate action moves the price by more than 2 per cent (dividend, bonus, split, rights)
Validity disable	An alert has a 365-day validity and is auto-disabled after it unless triggered or disabled earlier
Instrument-change disable	Delisting, suspension, series change, or a derivative contract expiry disables the alert
Alert limit	500 alerts and 200 ATOs per account; you cannot create more until you delete some (Zerodha support, June 2026)
How you find out	Kite emails you when an alert is auto-disabled
The fix	Review the condition is still valid, then re-enable the alert or recreate it in the Alerts section

Procedure

Read the disable email and open the Alerts sectionKite emails you when an alert is auto-disabled. Open the Alerts section under Orders, or kite.zerodha.com/orders/alerts on web, to see which alerts are now in the disabled state.
Identify the disable reasonMatch the instrument to its recent history. A price gap over 2 per cent from a corporate action, a derivative expiry, a delisting or series change, or an alert older than 365 days each disables the alert. Knowing the reason tells you whether re-enabling still makes sense.
Re-check that the condition is still meaningfulAfter a corporate action the price level you set may no longer correspond to anything. A 460 alert on a stock that did a 1:1 split now trades near 230 means little. Recompute the level on the adjusted price before re-enabling.
Re-enable the alert or recreate itIf the condition still holds, toggle the alert back to enabled in the Alerts section. If the level needs changing, edit it, or delete and recreate the alert with the adjusted condition so it monitors the right level.
If you hit the alert limit, free slotsIf Kite refuses a new alert, you are at the 500-alert or 200-ATO cap. Delete stale, triggered, or expired alerts from the Alerts section to free slots, then create the alert you need.
For an expired derivative, set the alert on the live contractAn alert on an expired F&O contract cannot be re-enabled meaningfully because the contract no longer exists. Create a fresh alert on the current-month or relevant live contract instead.

Kite auto-disables a price alert for a small set of defined reasons: a corporate action that moves the instrument’s price by more than 2 per cent, a derivative contract expiry, a delisting, suspension or series change, or the lapse of the alert’s 365-day validity. Separately, you cannot create a new alert once you hit the account cap of 500 alerts or 200 ATOs . A disabled alert no longer monitors anything, so a level you set and forgot can quietly stop watching. Kite emails you whenever an alert is disabled, which is the prompt to act.

This guide explains each disable reason, why the 2 per cent corporate-action rule exists, how to decide whether re-enabling still makes sense, the exact re-enable flow, and how to free slots when you have hit the limit. The fix is rarely just flipping the alert back on; after a corporate action the price level itself usually needs recomputing.

The disable reasons, and what each means

Kite turns an alert off automatically in these situations.

Disable reason	What happened	What to do
Corporate action over 2 per cent	A dividend, bonus, split, or rights issue moved the price discontinuously	Recompute the level on the adjusted price, then re-enable or recreate
365-day validity lapse	The alert reached the end of its one-year life without triggering	Re-enable or recreate if you still want the level watched
Derivative expiry	The futures or options contract the alert was on expired	Create a fresh alert on the live contract
Delisting, suspension, series change	The instrument changed or stopped trading	Re-evaluate; the old alert may no longer apply
Triggered	The alert fired and turned itself off	Recreate if you want to watch the condition again
Alert limit reached	You are at the 500-alert or 200-ATO cap	Delete stale alerts to free a slot, then create the new one

The first four are the genuine auto-disables that surprise people. The last two, a fired alert and the cap, are not strictly “disabled” in the error sense but produce the same outcome: no monitoring, and in the cap case, no ability to create a new alert.

Why a corporate action over 2 per cent disables the alert

This is the disable reason worth understanding, because the fix is not just re-enabling. When a company does a bonus issue, a stock split, a rights issue, or pays an extraordinary dividend, the price adjusts discontinuously on the ex-date. A 1:1 bonus roughly halves the price; a 1:5 split quotes the stock at a fifth of its prior level; an extraordinary dividend drops the price by the dividend amount on the ex-date. Your alert level was set against the pre-action price. If it kept running, it would fire spuriously against the adjusted price, because a “below 250” alert on a stock that just split from 500 to 250 is now sitting on top of the price.

Kite’s rule is to disable any alert on an instrument whose price a corporate action moves by more than 2 per cent. The 2 per cent threshold separates an ordinary dividend (small, no adjustment needed) from an event that meaningfully resets the price. The disable is protective: it stops a stale level firing, and forces you to recompute the level against the adjusted price before the alert watches again. So the correct fix is to work out where your level sits on the new price, edit the alert to that level, and re-enable it, not to flip it back unchanged.

Step-by-step procedure

The infobox at the top gives the sequence. The detail below expands the diagnosis and the recompute step, which is where the real work is.

1. Read the disable email and open the Alerts section

Kite emails you when an alert is auto-disabled, so the email is your first signal. Open the Alerts section: Orders, then Alerts on web or app, or kite.zerodha.com/orders/alerts directly. Disabled alerts show in the list in a disabled state, distinct from your active ones.

2. Identify the disable reason

Match each disabled alert to its instrument’s recent history. Did the stock go ex-bonus, ex-split, ex-rights, or pay a large dividend in the last few sessions? Did the F&O contract expire? Was the scrip delisted, suspended, or moved to a new series? The reason determines whether re-enabling is even sensible: an alert on an expired contract has nothing to monitor, while a corporate-action alert needs its level recomputed first.

3. Re-check that the condition is still meaningful

For a corporate-action disable, the old level usually no longer means anything. An alert to buy “below 460” on a stock that did a 1:1 split now trades near 230 is pointing at a level the stock cleared on the ex-date. Recompute: if your thesis was “buy 8 per cent below the pre-split 500,” that is roughly 230 on the adjusted price, not 460. Do this arithmetic before you touch the enable toggle.

4. Re-enable the alert or recreate it

If the condition still holds unchanged, toggle the alert back to enabled in the Alerts section. If the level needs to change, edit the alert to the recomputed level, or delete it and recreate it with the adjusted condition. Either way the alert resumes monitoring once enabled with a valid level.

5. If you hit the alert limit, free slots

If Kite refuses a new alert outright, you are at the 500-alert or 200-ATO cap, not facing an auto-disable. Open the Alerts section and delete stale entries: triggered alerts that linger, expired-contract alerts, and alerts on instruments you no longer trade. Each deletion frees a slot. There is no bulk-clear, so work through them, then create the alert you wanted.

6. For an expired derivative, set the alert on the live contract

An alert on an expired future or option cannot usefully be re-enabled, because the contract no longer trades. Recreate the alert on the current contract instead: the new-month future, or the relevant live option. If you regularly alert on F&O, expect to refresh these alerts each expiry as contracts roll.

How you learn an alert was disabled

Kite sends an email notification whenever an alert is disabled. That email is the system’s only proactive signal, so the registered email on your account must be current and the message must not be filtered to spam. If you rely on alerts for risk management, treat a disable email as actionable, not informational: a disabled alert is a level you think is being watched but is not. The notification channels reference covers the email and push behaviour in full.

What can go wrong

You re-enable a corporate-action alert without recomputing the level. A split or bonus reset the price; the old level is now meaningless. Recompute on the adjusted price first, then re-enable, or the alert fires immediately or never.
You try to re-enable an expired-contract alert. The contract no longer exists, so there is nothing to monitor. Create a fresh alert on the live contract.
You assume the alert is still watching after a corporate action. A disabled alert does nothing. If you did not see or act on the disable email, a level you rely on may have been off for days.
You hit the cap and read it as a bug. Kite blocks new alerts at 500 alerts or 200 ATOs. Delete stale alerts to free slots; there is no error to “fix” beyond clearing room.
The disable email went to spam. The notice is your only proactive signal. Check spam and keep the registered email current, or you will not know an alert went dark.
A 365-day-old alert quietly lapsed. Set-and-forget alerts auto-disable after a year. Re-enable or recreate any long-dated levels you still depend on.

Frequently asked questions

Why did my Kite alert get disabled on its own?

Kite auto-disables an alert for a corporate action that moves the price by more than 2 per cent, a derivative contract expiry, a delisting, suspension or series change, or the lapse of the 365-day alert validity. It emails you whenever an alert is disabled.

Why does a corporate action disable my alert?

A bonus, split, rights issue, or extraordinary dividend changes the price discontinuously. Your alert level was set against the old price, so it would fire spuriously on the adjusted price. Kite disables it so you can recompute the level against the adjusted price and re-enable it.

How do I re-enable a disabled Kite alert?

Open the Alerts section under Orders at kite.zerodha.com/orders/alerts, find the disabled alert, confirm its condition still makes sense, and toggle it back to enabled. If the price level no longer fits, edit it or recreate the alert with the adjusted level.

Why can't I create a new alert on Kite?

You have likely hit the account cap of 500 alerts or 200 ATOs. Kite will not let you create another until you are below the cap. Delete stale or triggered alerts from the Alerts section to free slots, then create the new alert.

Is the 2 per cent corporate-action threshold on the alert or the stock?

It is on the instrument’s price. When a corporate action shifts the price by more than 2 per cent, such as a bonus, split, rights issue, or extraordinary dividend, Kite disables the alerts on that instrument so a stale level does not fire against the new price.

Can I re-enable an alert on an expired contract?

Not meaningfully. Once a futures or options contract expires it no longer exists, so an alert on it has nothing to monitor. Create a fresh alert on the live contract, the current-month future or the relevant active option, instead.

How long does a Kite alert stay active?

An alert has a validity of 365 days. After that it is auto-disabled unless it triggered or you disabled it earlier. A set-and-forget alert that never fires is therefore turned off a year on, and you re-enable or recreate it if you still want the level watched.
