Tokyo Stock Exchange’s arrowhead 4.0 cash-equity system is scheduled to increase daily order-processing capacity from 830 million to 1.5 billion on 30 November. JPX disclosed the upgrade on 23 October as part of a broader market-infrastructure and asset-building programme.[1]
Capacity and fee timetable
| Measure | Change | Timing |
|---|---|---|
| Daily order capacity | 830 million to 1.5 billion | Scheduled 30 November 2026Source 1 |
| Calculated additional capacity | 670 million orders, approximately 80.7% | Design capacity, not observed flowSource 1 |
| Retail investor market-data terminals | Fee reduction | January–December 2027Source 1 |
| Cash-equity trading access | Lower access fees | From March 2027Source 1 |
The percentage increase is calculated as (1,500 − 830) ÷ 830 × 100. It describes how many orders the system is designed to process in a day. It does not measure execution latency, the number of completed trades or the volume customers actually submit.[1]
JPX also describes a 24/7 incident-response framework, stronger backup protection and geographically remote continuity facilities. The fee initiatives have a separate commercial timetable: they reduce specified exchange or data charges, while the release gives no uniform reduction in brokers’ retail commissions.[1]
