Sports Exchange Platform Development — Order Books, P2P & Liquidity

Every market has a back/lay order book identical in structure to a financial exchange. We implement matching as a price-time priority engine in Rust or Go, capable of 200k+ matches per second per shard. State lives in memory with a Postgres or Cassandra audit log.

• Back and lay orders matched at the best available price.
• Partial-fill support with FIFO time priority.
• Per-market liability calculated in real time.
• Cancel and amend supported with sub-50 ms latency.

Standard is 2–5% on net winnings per market. Loyalty discounts (commission reduction for high-volume users) drive retention. We implement commission as a post-settlement adjustment in the ledger to keep the matching engine pure.

Empty order books are the #1 killer of new exchanges. Seed liquidity with a market-maker bot tied to a primary odds feed (Sportradar, Betfair Exchange API or your own trader desk). Start at 2–4% spread and tighten as real users arrive.

Exchanges attract bonus abuse, wash-trading and match-fixing alerts. Build a real-time surveillance layer that flags self-matching, repeated price manipulation and unusual volume on lower-tier events. Integrate with Sportradar Integrity Services for tier-1 leagues.

70%+ of exchange volume in 2026 comes from mobile. Ship a React Native or PWA front-end with one-tap betting, persistent order book and in-play streaming. Latency budget end-to-end: under 350 ms from price tap to confirmation.
