Stale-Quote Protection API for Arb Bots
Build a real-time risk layer that monitors source-odds freshness, fair-value drift, and fill conditions, then automatically cancels or blocks passive orders before they become toxic. The clearest commercial value is direct P&L protection for small-to-mid-sized algorithmic traders already running bots but lacking exchange-grade controls.
Pourquoi c'est important
You already built the trading bot, found a real cross-venue edge, and even generated gross profits. The problem is that your passive orders sit in the book while your external odds snapshot quietly ages. By the time you get filled, someone faster often knows the fair price has shifted, so your winning trade idea turns into residual exposure and silent losses. Generic bot frameworks help with order placement, but they do not act like a dedicated protection layer that knows when your reference data is too old to trust. You need software that sits between signal and execution and prevents bad fills before they happen.

Périmètre MVP · 1–2 semaines
- Define a normalized schema for external odds, local quote timestamps, and exchange orders.
- Build a small ingestion service that accepts odds updates through REST and stores quote age in Redis.
- Create a rules engine for max quote age, max fair-value drift, and stale-market pause logic.
- Expose a webhook that returns allow, cancel, or pause decisions for each order.
- Build a basic dashboard showing market freshness and triggered protections.
- Add one prediction-market integration and one sample odds-source connector.
- Implement auto-cancel recommendations and alerting through Telegram or email.
- Create an order replay tool to test the protection layer on historical fills.
- Add toxicity scoring based on fill timing relative to source updates.
- Launch a closed beta with 3-5 traders using paper-trading or read-only mode first.
Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1The strongest value claim depends on measurable latency and avoided losses, and many users may not trust a product unless it proves P&L improvement quickly.
- 2A niche market of technically capable traders may prefer to implement freshness rules internally once the problem is obvious.
- 3Source integrations can break often, making support burden high relative to revenue if the product depends on scraping.
Résumé des preuves
Comment l'IA a synthétisé cet aperçu — pas de citations textuelles
The core pattern appeared repeatedly: the strategy made money before residual losses, and several participants independently linked those losses to stale external odds and informed counterparties. Multiple comments converged on quote age as the main diagnostic variable, with suggested fixes centered on faster updates, freshness thresholds, and automated order suppression. That makes a prevention-focused software layer the most direct and commercially credible opportunity.
