A prop firm's pricing requirements depend on whether its environment is simulated, evaluated or connected to live execution.
Identify which accounts consume simulated prices and which use production references. Keep test and replay feeds clearly labelled, and define how displayed prices relate to challenge evaluation, risk calculations and any executable liquidity path.
Verify symbol precision, session availability and the quote basis used for evaluation. Retain the event context needed to investigate disputed fills or stale prices without claiming that a reference feed alone establishes execution quality.
Bring the proposed instrument list, source documentation and consumer workflow to a technical discussion. The agreed integration specification defines coverage, fields, usage permissions and acceptance tests.
| Instrument scope | Identify the exact underlying, source identifier, quote currency and intended use. |
|---|---|
| Consumer workflow | List trading platforms, charts, risk tools and applications that need the output. |
| Delivery contract | Agree protocol, quote fields, timestamps, source status and recovery behaviour. |
| Production review | Confirm source rights, integration ownership, test evidence and commercial scope. |
For your instrument universe, define who consumes the prices and what each system needs to reconstruct a usable quote. An application dashboard, broker platform and historical process can require different delivery rules even when they share one normalized instrument model.
