Case Study
Overview
Built a real-time arbitrage alerting system that aggregates prices across exchanges, normalizes spreads, and notifies users when opportunities cross configured thresholds.
Problem
Traders were manually checking multiple exchanges and missing short-lived spreads. Data was inconsistent across sources, and raw price differences ignored fees, causing noisy alerts.
Solution
A Rails-based backend with a price aggregation layer, alert rules engine, and a lightweight dashboard for managing watchlists and reviewing alerts.
Goals
- 1Monitor multiple exchanges and surface opportunities in near real time.
- 2Normalize spreads by accounting for fees and transfer constraints.
- 3Deliver alerts fast enough to act on short-lived opportunities.
- 4Reduce duplicate or low-quality alerts from volatile price swings.
- 5Provide a simple dashboard to track alert history and performance.
Approach
- Pulled ticker data on a fixed cadence and normalized symbols across exchanges.
- Used Redis for caching and deduplication to avoid alert spam.
- Scheduled background jobs with Sidekiq to keep ingestion and alerting independent.
- Applied spread rules with configurable thresholds and minimum liquidity checks.
Results & Impact
Outcomes
- Improved visibility into multi-exchange spreads from a single view.
- Reduced missed opportunities by alerting within seconds of a valid spread.
- Cut noisy alerts by filtering out low-liquidity or fee-negative signals.
