TradingView Webhook Automation: The Complete Reference

A TradingView webhook is not a connection to your broker. It is an unauthenticated HTTP POST from a third party to a public endpoint you own, delivered with a three-second budget and no guarantee it arrives at all.

Shipping UI to a Live Trading Client Without a Redeploy: A Module Federation Case Study

Self-hosted trading clients create a deployment problem: how do you ship interface changes without making every user redeploy and interrupting live automation? Module Federation 2.0 with a Vue micro-frontend is the answer — the shell stays put while remotes update from the CDN. Here's how it works, and the shell-to-remote contract problems that make it hard.
