Ask what the product actually connects
Draw the platform-side interface, intermediary component and external destination. Then mark which flows pass through each connection: prices, orders, amendments, cancellations, executions and operational events. A diagram often exposes assumptions hidden by an umbrella product name.
Ask whether the component is supplied as software, a managed service or part of another provider’s environment. That boundary determines access, change control, troubleshooting and the practical exit route.
Use a function-based comparison
| Decision | Evidence to request | Why it matters |
|---|---|---|
| Supported actions | Interface/version matrix and representative event traces | A connection may support only part of the required workflow |
| Configuration ownership | Routing and mapping permissions, approval procedure | Your operators need to know which changes they can make |
| Dependency failure | Demonstrated interruption and recovery behaviour | Reconnect alone does not establish correct outstanding states |
| Portability | Exportable settings, records and replacement requirements | Changing providers can affect more than the endpoint |
For MT5, MetaQuotes documents platform gateways and integration APIs. A particular provider proposal still needs to specify which interfaces and rights are available. Do not infer a complete capability set from the platform name.
A practical selection exercise
Illustrative scenario: a broker needs an established pricing connection and a new external order route. One candidate may cover both in a single operating boundary; another may require separate adapters. Compare the total number of owners, failure points and reconciliation tasks using the same test cases.
Request a demonstration agenda that includes one successful workflow, one rejection, an interruption and the related operator view. Select the proposal that covers the agreed requirements with a support model your team can operate. Document exclusions before comparing commercial terms.
