Each exchange now routes to strategies that match its execution speed. XARB requires Tier 1 only. The system scans ~550 combinations across 6 exchanges. Infrastructure cost: unchanged at $26/month.
Here's what changed: the system now knows which exchanges are fast enough for which strategies. Cross-exchange arbitrage needs sub-second execution — only Tier 1 exchanges qualify. Mean reversion works fine with slower data — so Tier 2 and Tier 3 exchanges can participate.
This means every exchange contributes to the strategies it's matched to, instead of being excluded because it's too slow for one strategy.
The numbers:
- Before: 313 active trading combinations
- After: 550 active trading combinations
- Infrastructure cost change: $0
- Projected P&L impact: +75% from expanded route coverage
The system didn't need more hardware. It needed better routing. The infrastructure gate tracker confirmed the improvement over 7 days of monitoring before anything changed.
That's Phase 0 of the scale plan: extract maximum value from existing infrastructure before spending a dollar on expansion.
Frankfurt is next. When the gate tracker proves EU routes are worth it, the system will flag the expansion. Not before.
