TradingView Alerts & Webhooks Guide 2026 — Complete Tutorial

Why This Matters

TradingView Alerts Are the Trigger for Everything

TradingView is where your Pine Script indicators live and where market conditions are monitored. But TradingView itself doesn't execute trades — it fires alerts when conditions are met. Those alerts, sent via webhooks, are what connect your strategy to actual trade execution through software like Traders Post.

Without understanding how TradingView alerts and webhooks work, you can't automate anything. This guide covers everything from the basics to production-ready alert configuration.

Plan Requirements

Which TradingView Plan Do You Need?

Plan	Price	Webhooks	Simultaneous Alerts	For Automation
Free	£0	✗ No	1	Not suitable
Essential	~£12/mo	✗ No	5	Not suitable
Plus ⭐	~£20/mo	✓ Yes	20	Recommended
Premium	~£38/mo	✓ Yes	100	For multiple pairs

💡

TradingView Plus is the Sweet Spot

For most prop traders automating 2–5 strategies across a handful of pairs, the Plus plan at ~£20/month is sufficient. 20 simultaneous alerts is plenty. Upgrade to Premium if you're running automation across many instruments or timeframes.

Alert Types

The Four Types of TradingView Alerts

Understanding which alert type to use is critical — using the wrong type is the most common cause of automation errors.

Script Alert (alertcondition)

Triggered by a Pine Script alertcondition() function in your indicator. This is what you use with the PropHub free indicators. The most reliable and controllable alert type for automation.

Price Cross Alert

Triggers when price crosses a specific level. Simple but limited — cannot pass dynamic data like current price in the webhook message without Pine Script.

Drawing Alert

Triggers when price crosses a line or shape drawn on the chart. Useful for manual level-based automation but harder to manage at scale.

Strategy Alert (strategy.entry)

Triggered by Pine Script strategy functions. Works but alertcondition() in an indicator gives you more control over exactly when signals fire.

Creating Alerts

How to Create a Webhook Alert — Step by Step

Open the Alert Dialog

Right-click on the chart → Add Alert, or press Alt+A. The Create Alert dialog opens.

Set the Condition

Under Condition, select your indicator name from the first dropdown (e.g. PropHub — Extended VWAP Reversal). In the second dropdown, select the specific alert condition (e.g. VWAP Reversal — LONG).

Set Trigger Frequency

Select Once Per Bar Close in the Trigger dropdown. This is the most reliable setting for automation — the alert only fires once, at the close of the bar where the condition was met.

Set Expiry to Open-Ended

Under Expiry, select Open-ended alert. TradingView alerts expire after 2 months by default — set to open-ended so your automation doesn't silently stop working.

Enable Webhook URL

Scroll to the Notifications section. Enable the Webhook URL checkbox. Paste your Traders Post webhook URL in the field that appears.

Add the JSON Message

In the Message box, paste your JSON alert message. This is the payload Traders Post receives. Use {{ticker}} and {{close}} placeholders to insert dynamic values.

Placeholders

TradingView Alert Placeholders

TradingView supports dynamic placeholders in alert messages that are replaced with real values when the alert fires. These are essential for building flexible JSON messages.

Placeholder	Replaced With	Example
`{{ticker}}`	Chart symbol	EURUSD
`{{close}}`	Bar close price	1.08524
`{{open}}`	Bar open price	1.08510
`{{high}}`	Bar high price	1.08540
`{{low}}`	Bar low price	1.08480
`{{volume}}`	Bar volume	12453
`{{timenow}}`	Current timestamp	2026-05-01T08:30:00Z
`{{interval}}`	Chart timeframe	15

Troubleshooting

Common Alert Problems & Fixes

🚨

Alert Fires But No Trade Executes

Check: (1) Webhook URL is correct and matches Traders Post exactly, (2) JSON message is valid — no extra spaces or missing quotes, (3) Traders Post strategy is active and connected to the right broker, (4) TradingView plan supports webhooks (Plus or higher required).

⚠️

Alert Fires Multiple Times on Same Bar

Change your alert trigger from "Once Per Bar" to "Once Per Bar Close". The "Once Per Bar" setting fires whenever the condition is true within the bar — which can be multiple times on lower timeframes. "Once Per Bar Close" fires once only, at the candle close.

💡

Testing Your Webhook

In Traders Post, use the Send Test button to manually fire a test webhook and confirm receipt. Also check TradingView's Alert Log (the clock icon in the Alerts panel) to see a history of fired alerts and any delivery errors.
