The Challenge

Active traders need to monitor multiple stock positions simultaneously but can't watch screens all day. Existing solutions are too complex, require expensive subscriptions, or lack reliable mobile notifications that actually get seen.

The Solution

A professional Windows desktop application that monitors stock prices in real-time and sends instant alerts via both Windows toast notifications and WhatsApp messages when prices cross user-defined thresholds. It runs silently in the system tray with zero subscription fees.

Key Features

Real-time price monitoring for up to 15 stocks with configurable intervals and automatic market hours detection
Multi-channel alerts: Windows toast notifications with audio plus WhatsApp mobile messages via Meta's WhatsApp Cloud API
Cloud monitor on Cloudflare Workers checks prices every 5 minutes during market hours — alerts arrive whether or not the PC is running
Smart consolidated notifications — multiple alerts combined into a single notification per check cycle
Bilingual interface (EN/ES) with multi-currency display toggling between USD and MXN with live exchange rates
Background service runs silently in system tray — alerts work even when UI is closed, auto-starts with Windows

Results

Sub-2-second alert delivery from price change detection to notification
15 stocks monitored simultaneously on free tier
60 API calls/minute rate-limited token bucket for optimal Finnhub usage
