## Summary

A focused service for MT4/MT5 estates, Bridge/Gateway paths and the host, storage, network and cross-region conditions around them. Apsiren is independent of MetaQuotes Ltd. and does not provide vendor support.

## Trading infrastructure scope

The agreed question determines which execution path, infrastructure layer and operating boundary are examined.

### Order execution latency

Assess order execution latency against an evidence-backed baseline across the agreed symbols, paths and time periods.

### Bridge / Gateway paths

Trace Bridge and Gateway dependencies, queues and hand-offs without treating vendor internals as Apsiren-owned.

### Host and storage

Review host placement, storage behaviour, capacity signals and the failure modes that affect the trading path.

### Network path

Map network dependencies, packet-loss evidence and the boundaries between local, hosted and provider-controlled paths.

### Cross-region behaviour

Compare the agreed regional paths and failover assumptions using the evidence available from each side of the boundary.

### Observability

Define signals, logs, traces and alerts that let the team explain a latency or availability symptom.

### Release and change

Review deployment sequencing, approval boundaries, validation and a tested rollback path for infrastructure changes.

### Backup and recovery

Check backup coverage, restore evidence and recovery dependencies without promising an outcome outside the agreed scope.

## Evidence across the path

The minimum source set is agreed before collection and kept tied to the question being answered.

- MT4/MT5 server journals, client logs and order timing records
- Bridge/Gateway output, host events, storage signals and network observations
- Cross-region failover, backup and restore evidence from the agreed test path

## Operating boundaries

Trading infrastructure work stays within the approved engineering question and change process.

- Apsiren does not provide trading signals, strategy or trading decisions.
- Production changes require named owners, validation, rollback and separate approval.
- Third-party products and vendor-controlled availability remain outside Apsiren's ownership.

## Independent service boundary

Apsiren is independent of MetaQuotes Ltd. and does not replace vendor support. Vendor responsibilities remain with the applicable vendor.
