News Latency: Information Travels, So Should You
In event-driven markets, a delay of seconds can invert your edge. News travels fast; your models need to keep pace.
Optimizing news ingestion and reaction paths ensures signals act on fresh information rather than stale headlines.
Why it matters
Slow news flow creates asymmetric information. Competitors reacting first capture alpha while laggards trade on leftovers.
Common mistakes
- Relying on a single vendor feed.
- Skipping latency measurement for news data.
- Letting strategies fire when feeds lag significantly.
Implementation steps
Use multiple feeds
Subscribe to redundant providers and compare arrival times.
Timestamp ingestion
Record when each headline hits to monitor delays.
Throttle on lag
Suspend or hedge strategies when news latency spikes.
