24/7 Serverless Rate Alert Architecture Specification
As specified in the technical roadmap, reliable 24/7 off-site rate alert processing requires decoupled background services rather than client-side browser timers. Below is the deployment blueprint:
Stores user alert subscriptions, target trigger values, hashed email tokens, and notification history:
CREATE TABLE rate_alerts (
id UUID PRIMARY KEY DEFAULT gen_random_uuid(),
email VARCHAR(255) NOT NULL,
currency_pair VARCHAR(10) NOT NULL,
target_rate NUMERIC(12, 4) NOT NULL,
condition VARCHAR(10) NOT NULL CHECK (condition IN ('above', 'below')),
is_active BOOLEAN DEFAULT TRUE,
created_at TIMESTAMP WITH TIME ZONE DEFAULT NOW()
);
Runs every 15 minutes via CRON trigger: fetches wholesale rate feed from live interbank sources, queries active target alerts, and triggers dispatch.
Sends templated alerts with SPF/DKIM verification, rate limiting (maximum 1 notification per 24 hours per pair to prevent inbox spam), and 1-click unsubscribe tokens.
Currently active on this frontend: checks rates on every live sync and raises immediate browser notifications and audio chimes while you browse.

Synced: LiveHow Foreign Exchange Rate Alerts Work
Currency markets trade 24 hours a day across global financial hubs. Setting a rate alert helps international businesses, frequent travelers, and remitters monitor key support and resistance price points without constantly watching ticker screens.
When you create an alert, the system monitors real-time wholesale exchange rates from official interbank feeds. When the threshold condition is met (whether the rate rises above or drops below your target), an immediate alert notification is triggered.
