Quick answer: a well-built alert turns your chart into a watchman that works while you do not. The trick is firing it on bar close rather than on every tick, so you stop receiving warnings that vanish seconds later. A webhook is simply the message TradingView sends to another service when the alert triggers — that message is the bridge between a signal and a real order in your account.
Key takeaways
- “Once per bar close” removes about 90% of false alerts.
- The alert message should carry instrument, direction, price and signal type — not generic text.
- A webhook does not execute; it hands the notice to a service that can.
- There is always latency between alert and order. Measure it before trusting the chain.
The three alert types you will actually use
| Type | Fires when | Used for |
|---|---|---|
| Price alert | Price touches a level | Watching supports, resistances and zones |
| Indicator alert | The indicator meets a condition | Flagging an entry or exit signal |
| Strategy alert | The strategy opens or closes | Sending orders to an external executor |
How to configure an alert that does not lie to you
- Condition: pick the indicator and the specific signal, not “any change”.
- Frequency: once per bar on close. Firing on every tick produces alerts that later disappear.
- Expiry: match it to your trading horizon; an alert left open for months is noise.
- Message: include instrument, direction, timeframe and price. “Signal” tells you nothing afterwards.
- Channel: app notification if you trade manually, webhook if you want automatic execution.
What a webhook really is
When the alert fires, TradingView sends a message to a web address you provide. That service receives the notice and decides what to do: log the signal, forward it, or open an order at your broker. TradingView never trades your account; it only notifies.
Three basic safety rules:
- Never put sensitive data in the alert text.
- Use a service that lets you cap risk, instruments and schedule.
- Always test on demo before connecting a live account.
The full chain: signal → alert → order
| Step | What happens | Where time is lost |
|---|---|---|
| 1. Signal | Indicator confirms on bar close | Waiting for confirmation (necessary) |
| 2. Alert | TradingView sends the notice | Seconds |
| 3. Executor | The service turns the notice into an order | Seconds |
| 4. Broker | The order reaches the market | Slippage in volatile moments |
Compare that with the manual route: you see the notification, unlock the phone, open the platform, calculate the lot and enter. That is minutes, not seconds.
Common mistakes when automating with alerts
- Leaving the alert on “every tick” and executing signals that later vanish.
- Omitting the instrument from the message and trading the wrong symbol.
- Ignoring the clock: the alert fires overnight and the order fills on a wide spread.
- Automating a system that was never measured on demo.

Frequently asked questions
Are TradingView alerts free?
The free plan allows a limited number of active alerts; paid plans raise the limit and add features such as webhooks.
Do alerts work if I close my browser?
Yes. Alerts run on TradingView's servers, so they fire even with your computer off.
What is the difference between an alert and a signal?
The signal is the trading condition; the alert is the notice telling you about it. A good signal with a bad alert arrives late.
Can a webhook trade on its own?
Not by itself. It needs a service that receives the message and has permission to send orders to your broker.
How much latency is acceptable?
For intraday indices and Gold, a few seconds. The smaller your average target, the more each second costs.
