TradingView lets you build indicators and strategies in Pine Script and fire alerts when conditions are met. Those alerts can send a webhook to your server with a JSON payload—symbol, direction, quantity, or custom fields. The missing piece is turning that webhook into a real order at your broker. That’s the pipeline we build for clients: receive alert → validate and apply risk rules → send order to Interactive Brokers (or another broker) → log and monitor.
How TradingView webhooks work
In TradingView you create an alert and choose “Webhook URL.” When the alert triggers, TradingView sends an HTTP POST to your URL. The body can be the default message or a JSON you design in Pine (e.g. {"symbol": "{{ticker}}", "side": "buy", "qty": 10}). Your server must be reachable from the internet and respond quickly so TradingView doesn’t retry unnecessarily. You should also handle duplicate alerts (idempotency) and validate the payload before doing anything.
Risk checks before execution
Blindly executing every webhook is dangerous. We typically add: (1) Symbol allowlist — only trade symbols you’ve approved. (2) Position and size limits — max position size, max order size, or max daily volume. (3) Rate limiting — cap how many orders per minute or per symbol. (4) Optional manual gate — e.g. require a second confirmation for large orders. These run on your server before any call to the broker API.
Connecting to the broker
Once the signal passes your checks, the next step is to place an order. We often use Interactive Brokers’ TWS API or Client Portal API: translate the signal (symbol, side, quantity, maybe limit price) into an IB order type (market, limit, etc.) and submit. You need to handle rejections, partial fills, and connection drops—and keep an audit log of all signals and orders for compliance and debugging.
What we build for you
At FintechPaa we build the full chain: webhook receiver, validation, risk layer, and broker integration (e.g. IB). We can also design custom Pine indicators or strategies and wire their alerts to your execution service. The result is a robust signal-to-order pipeline so you can run strategies 24/7 without manually copying trades. If you want to go from TradingView idea to live execution, we can build it for you.
