Quick answer

Store the provider observation time, not only the time the UI rendered.

Every market statement needs a unit, provider and timestamp. A listing is an observation; it is not a promise of liquidity, execution or future value. A freshness policy for market scanners and arbitrage tools.

KEY TAKEAWAYS
✓

Store the provider observation time, not only the time the UI rendered.

✓

Define a maximum age appropriate to the use case.

✓

Mark old values as stale and stop calling them opportunities.

✓

Provider outages should degrade to Unavailable without synthetic replacements.

How to read the data

Begin with the exact record involved: item name, variant, source and observation date. Then separate a factual game-data field from an estimate, community convention or market inference. This sequence keeps a helpful shorthand from becoming a false claim.

Common mistakes

DON'T

Treat a listing as a sale

Asking prices can be stale, manipulated or far from executable demand.

DON'T

Hide model assumptions

Fees, odds and freshness windows must stay visible and editable.

DO

Match the exact variant

Wear, pattern, StatTrak, Souvenir and event identity can change the record.

DO

Keep an unavailable state

Missing evidence should remain missing instead of becoming fabricated data.
