TradingView Strategy Automation with Python and Webhooks

Pine Script is excellent for backtesting but has no direct order-execution surface for retail exchanges. Python fills the gap. Here is the production stack I ship most often.

Why Python

Every major exchange has a maintained Python SDK.

`pandas` and `numpy` make position and risk math trivial.

Async frameworks handle bursty webhook traffic cleanly.

Deployment on a small VPS or a Cloud Run container is a five-minute job.

The Full Pipeline

Pine Script strategy fires an alert on bar close.

Alert POSTs JSON to a Python webhook.

Webhook validates a shared secret and shape.

A queue (Redis or asyncio) hands the signal to the executor.

Executor sizes, places, and logs the order.

Metrics stream to Grafana or a Telegram bot.

Structuring the Payload

Design one payload shape and reuse it across every strategy. Passing stop-loss and take-profit inside the alert lets the bot bracket the order the moment it opens — no second round trip.

Position Sizing in the Bot, Not the Chart

Pine's built-in sizing does not know your live account balance. Let Python size trades from actual equity using fixed fractional risk.

Deployment Checklist

HTTPS only.

Systemd service with auto-restart.

Env vars for API keys — never in the repo.

Structured JSON logs shipped to Loki or CloudWatch.

Health endpoint TradingView can ping.

Monitoring

Two dashboards are enough: execution (fills, rejections, latency) and PnL (equity curve, drawdown, per-strategy PnL). Alert on rejection spikes and any drawdown breach.

Wrap-Up

The stack is boring on purpose. Boring is what survives a live market at 3 a.m.
