When to evaluate Tokyo
Tokyo is a candidate for an endpoint in Japan or a workflow with Northeast Asian dependencies. A broker offering Asian markets may still host its account service elsewhere, so establish the connection destination first.
Asia is not one interchangeable hosting region. Compare Tokyo with Singapore only when both are relevant to the actual destination. If a program also calls a European or US service, document that second route; moving the terminal changes more than the broker connection.
Tokyo route-selection checklist
| Check | Action |
|---|---|
| Japan destination | Confirm the selected broker service instead of inferring it from instrument coverage. |
| Regional comparison | Test Singapore or another proposed region only against the same destination. |
| External dependencies | Record signal, licensing or data services reached outside Northeast Asia. |
| Observation window | Include the Asia-session periods that are relevant to the program. |
Test before selecting the region
- Record the account server selected in the terminal and ask the broker for a suitable test destination.
- Request a test environment for the proposed region if one is available. Record the actual environment, method, date and time zone.
- Compare repeat observations, including variation and failed attempts, during your relevant trading hours.
- Validate a demo terminal and its program dependencies on the selected environment.
What a Tokyo quotation should confirm
For Tokyo, match the production proposal to the Northeast Asian test context. Confirm the available resources and region, and identify any external program dependency whose route crosses into another region.
Document the EA startup and recovery process as well as the Japan-facing connection. If remote administrators work across time zones, agree maintenance timing explicitly. Send the actual endpoint, external dependencies and representative terminal workload.
Availability and actual placement require written confirmation. No specific facility, co-location arrangement or fixed network delay is stated. See access and recovery planning.
Build a Tokyo comparison record
Use Tokyo as a candidate for Japan and nearby APAC endpoints. Keep the tested source, broker destination and observation window identifiable so the result can be compared later.
| Decision | Practical check |
|---|---|
| Japan destination | Confirm whether the actual account endpoint is in Japan before prioritising Tokyo. |
| APAC comparison | Test Singapore separately when a workflow connects to Southeast Asian services. |
| Time-zone record | Save UTC timestamps alongside any local session notes so observations can be aligned. |
Compare Singapore when its route is relevant, using the same endpoints and method. Keep remote administration and application-to-broker connectivity as separate observations. Review the required management and recovery scope alongside the route.
