Then nothing happened.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eOr worse, it happened twice, and you woke up holding double the position you chose.\u003c\/p\u003e\n\n\u003cp\u003eThis is the piece between \"TradingView fired\" and \"a server acted on it, exactly once.\" It is where most people building this stall, and it is the least interesting part of the job, which is exactly why nobody writes it carefully.\u003c\/p\u003e\n\n\u003ch3\u003eWhat it does\u003c\/h3\u003e\n\n\u003cp\u003eReceives a TradingView alert, proves it is genuine, throws away duplicates, and writes it down somewhere that survives a crash.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe same signal can never open two positions,\u003c\/strong\u003e because the alert id is the database key. If the insert did nothing, we have seen this alert before. No lock, no race, no second cache to keep in sync.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA restart mid-signal does not lose the queue,\u003c\/strong\u003e because it is on disk rather than in memory. A lost exit signal is a position that never closes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA slow broker cannot make you miss an alert.\u003c\/strong\u003e TradingView gives you three seconds and then gives up. The endpoint acknowledges in about two milliseconds and does everything slow on a worker nobody is waiting on.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou can watch it for a week before any money is involved.\u003c\/strong\u003e Trading is off by default, so out of the box it records and never touches a broker. That is a complete and useful thing on its own.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou can see what each test is defending against,\u003c\/strong\u003e not just that it is green. 91 of them, no network, no credentials, no broker account.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat is in the download\u003c\/h3\u003e\n\n\u003cp\u003eThe Pine strategy that emits the alert, the server that receives it, the full test suite, and a walkthrough that gets you from nothing to a real alert from your own chart landing in your own log. No server, no domain, no certificate and no money required. Budget an hour.\u003c\/p\u003e\n\n\u003ch3\u003eWhat this is not\u003c\/h3\u003e\n\n\u003cp\u003eI would rather you skip this than buy it expecting the wrong thing.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt is not a strategy.\u003c\/strong\u003e The Pine script included is a moving average crossover, the least special signal in existence. That is on purpose. This is the plumbing between a signal and a broker, and anything resembling an edge would be a claim I cannot make.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt has never traded real money.\u003c\/strong\u003e Everything here has been run on paper. The broker adapter has been exercised end to end against a paper account and never against a live one.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIt will not make you money.\u003c\/strong\u003e It removes one specific reason automation fails: signals arriving twice, arriving late, or vanishing when a process restarts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eYou will be at a keyboard.\u003c\/strong\u003e This is code you run, not a service you log into.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNot sure what you are building yet?\u003c\/h3\u003e\n\n\u003cp\u003eThis is one component, and it assumes you already know where it fits. If you want the whole path mapped first, in about an hour, start with \u003ca href=\"\/products\/algorithmic-trading-complete-guide\"\u003ethe roadmap\u003c\/a\u003e at $5.99. It contains no code, which is exactly why this exists.\u003c\/p\u003e\n\n\u003ch3\u003eWhy it costs nine dollars\u003c\/h3\u003e\n\n\u003cp\u003eBecause it took two evenings and four real bugs to get right, and because I would rather you owned it than read about it. The reasoning behind every decision, and the setup that builds the rest of the system for your strategy instead of a generic one, is what I actually sell.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIf it does not get you a real alert landing in your own log, tell me and I will refund it.
