PINE LIBRARY

StrategyWebhookJson

567
Overview

Open-source Pine library that builds JSON strings for strategy alert_message webhooks. Use it when a strategy should send structured trade signals to an external webhook receiver instead of plain alert text.

What it does

The library formats JSON payloads for three actions:
• open — new position (side, volume, stop loss, take profit, symbol, price)
• close — close by signal id
• modify — update stop loss and take profit for an existing signal id

Each payload includes secret, signalId, action, and symbol (from syminfo.ticker). Optional fields are omitted when not applicable. Strings are JSON-escaped.

Delivery modes (Mode enum)

• LocalOnly — returns an empty string (no JSON in alert_message)
• CloudOnly — returns JSON for webhook alerts
• Both — same as CloudOnly for alert_message output

How to use

1. Import the library into your strategy.
2. Call init(secret, mode) once and store the result in a var Config.
3. Pass the result of openMsg, closeMsg, or modifyMsg to strategy.entry, strategy.close, or strategy.exit via the alert_message parameter.
4. Create a strategy alert and set the webhook URL in TradingView alert settings (TradingView Plus or higher required for webhook URL field).

Example pattern

var cfg = init("YOUR_SECRET", Mode.CloudOnly)

strategy.entry("Long", strategy.long,
alert_message = openMsg(cfg, "Long", "buy", 0.1, sl, tp))

strategy.close("Long",
alert_message = closeMsg(cfg, "Long"))

Requirements

• Pine Script v6
• A strategy script (not an indicator)
• Webhook URL configured on the alert, not inside this library

Notes

signalId should be stable and unique per logical order so close and modify can target the correct open. The secret is included in the JSON body for authentication at the receiver.
