TradingView to FreqTrade Bridge
Sub-second executionA small, hardened production service that turns TradingView strategy alerts into real exchange orders in under a second. Roughly 150 lines of FastAPI doing one job reliably, with the security and observability a money-moving webhook actually needs.
The Problem
A strategy is worthless if it cannot execute.
TradingView is where the signal lives. The exchange is where the order has to land. Between them sits a gap that most retail setups fill with brittle copy-paste or unverified third-party webhooks that fail silently and move real money when they misfire.
The Solution
One service, locked down, end-to-end verified.
A FastAPI bridge receives the TradingView webhook, authenticates it, and forwards a typed order to FreqTrade for execution. IP allow-listing and a shared secret gate every request, structured logs make every fire auditable, and a verified paper trade proved the full path before anything ran live.

What it demonstrates.
- •Production signal-processing infrastructure with clean, auditable failure modes.
- •Security-first design on a service that moves money: authn, allow-listing, least surface area.
- •Small-and-correct over large-and-fragile. One service, one job, verified end to end.
