| Approach | Use case | What to verify | Main limitation |
|---|---|---|---|
| REST polling | Discrete market and account reads | Endpoint weights, limit scope, cadence | Bursts and stale observations |
| WebSocket stream | Continuous event updates | Sequence rules, snapshots, reconnect procedure | Missing events or stale local state |
| Order submission | Request a change in exposure | Client identifiers, permissions, precision | Timeout with uncertain acceptance |
| Reconciliation | Resolve local/exchange differences | Orders, fills, balances, timestamps | Relying on one incomplete observation |
Compare like with like
An API response is one observation of exchange state. A dependable integration also handles missing responses, stale data, and reconciliation.
Keep assumptions visible
Use the same amount, market, network, time window, and cost basis when those factors apply. Record the original source and check date for product-specific information. A low advertised fee is incomplete without the conditions that make it available.
Check the evidence
Separate an actual test result from a calculation or a statement in product documentation. A review should describe its method, scope, and unresolved questions. We do not assign star ratings or publish benchmark winners without evidence.
Run the numbers
Plan polling volume against a request limit you supply. This simple model does not simulate burst limits or endpoint weights.
