TradingView–MetaTrader Integration — Webhook Alerts That Place Real Trades

How the Bridge Works

TradingView Webhook Requirements You Must Design Around

Always check TradingView’s current webhook documentation, because plan requirements and limits can change. Source: TradingView webhook guide.

A Webhook Receiver That Acknowledges Fast and Rejects Bad Requests

import asyncio
import hmac
import json
import os
from fastapi import FastAPI, HTTPException, Request

app = FastAPI()
URL_TOKEN = os.environ["WEBHOOK_URL_TOKEN"]          # long random string, part of the URL
orders: asyncio.Queue = asyncio.Queue()
seen_ids: set[str] = set()                           # simple replay / duplicate guard

@app.post("/webhook/{token}")
async def webhook(token: str, request: Request):
    if not hmac.compare_digest(token, URL_TOKEN):
        raise HTTPException(status_code=404)         # do not reveal that the endpoint exists

    raw = await request.body()                       # TradingView may send text/plain
    try:
        data = json.loads(raw)
    except json.JSONDecodeError:
        raise HTTPException(status_code=400, detail="payload must be JSON")

    alert_id = str(data.get("id", ""))
    if alert_id and alert_id in seen_ids:
        return {"status": "duplicate"}               # same alert delivered twice: ignore
    seen_ids.add(alert_id)

    intent = {k: data.get(k) for k in ("symbol", "action", "volume", "sl", "tp")}
    await orders.put(intent)                         # a worker validates and executes later
    return {"status": "queued"}                      # answer well inside the ~3 s limit

The matching TradingView alert message could be: {"id":"{{ticker}}-{{time}}","symbol":"{{ticker}}","action":"buy","volume":0.1}. Placeholders such as {{ticker}} are filled in by TradingView when the alert fires.

Safeguards Built Into Every Bridge

Delivery Steps

1. 1

   Review your TradingView strategy

   We check that alerts fire at the moments you intend. Strategy logic that repaints or acts on unconfirmed bars is flagged first.

2. 2

   Design the alert payload

   A JSON schema for actions such as buy, sell, close, move stop, with symbol, size and optional stop and target.

3. 3

   Build server and executor

   Webhook server, queue, and the MT4/MT5 Expert Advisor or exchange connector.

4. 4

   Test on demo

   End-to-end tests with real TradingView alerts on a demo account, including failure scenarios.

5. 5

   Deploy and hand over

   Hosting on a VPS with auto-restart, documentation and monitoring. See VPS Setup & Bot Infrastructure.
