A live price needs a source and a timestamp
Why current-market answers should show where the quote came from, when it was observed and how fresh it is.

“What is the price now?” sounds like a simple question, but a useful answer has more than a number. It needs an instrument, a source and an observation time. Without those fields, a value copied from an earlier conversation can look current even when the market has moved.
Freshness is a property of data, not of prose. A model can produce a fluent sentence from stale context. The system handling the request should recognise a current-price question, fetch a quote from an approved provider and preserve the provider timestamp. If the quote is unavailable or too old for the task, it should say so rather than filling the gap from memory.
Resolve the instrument explicitly
“BTC” may mean a spot pair, a perpetual contract or a broker-specific symbol. Resolve the instrument before displaying a quote and keep the source’s symbol alongside the user-friendly label. This avoids silently comparing values that represent different markets.
Make the handoff inspectable
Store or display the source, observed-at time and freshness status. A price response should not imply execution availability; a quote is information, while an order also depends on permissions, liquidity, spread, quantity rules and risk checks. Those are separate decisions.
The same discipline applies to charts, alerts and email. A static message should not carry levels that can become stale after delivery. Current trade details belong in the live, guarded interface where the data and controls can be checked together.
Fresh data does not make a market predictable. It makes the information boundary honest, which is a prerequisite for responsible decisions.
