OTC Quote Aggregator & Alert Service

A dedicated quote-aggregation service that scrapes and normalizes real-time bid/ask data from multiple OTC market makers (Pink Sheets, OTC Markets Group, broker APIs, Level 2 feeds) and delivers unified, timestamped quotes to retail traders via API, webhook, and mobile app. Includes alerts when spreads widen, volume spikes, or price targets are hit.

SERVICE

23 weeks • 70% confidence

Value Proposition

Eliminates 30-minute to 4-hour quote delays by directly connecting to market maker feeds; traders see true bid/ask within 2-5 seconds instead of broker delays. Reduces slippage on execution by 15-40% because orders are placed with current market data, not stale quotes.

Target Audience

Active OTC traders (penny stock traders, micro-cap speculators, day traders) who trade 5+ times per week and currently use multiple browser tabs or outdated broker quotes

Key Features

  • Real-time aggregation from 8+ OTC market maker sources (e.g., OTC Markets Group API, broker Level 2 feeds, alternative trading systems)
  • Normalized, deduplicated quote stream (handles duplicate/conflicting data from multiple sources)
  • Customizable alerts: spread widening, volume threshold, price targets, bid/ask divergence
  • And more, with full implementation detail...

Tech Stack

Python (data ingestion, quote normalization) Kafka or Redis Streams (real-time quote pipeline) PostgreSQL (time-series quote storage) Node.js (alert engine, API server)

Original Problem

Retail investors cannot access real-time stock prices for OTC and penny stocks

Individual investors trading over-the-counter (OTC) stocks like OTGLF face severe delays in price quotes, sometimes hours or days behind actual market prices. This information gap causes investors to make trades based on stale data, leading to unexpected slippage, poor execution prices, and potential financial losses. Free and standard brokerage platforms don't prioritize OTC quote updates, leaving retail traders at a significant disadvantage compared to institutional traders with real-time feeds.
