Does FXpeek invent weekend rates?
No. The displayed source date should remain the latest available provider date.
Rate convention
Which daily exchange rate should I use for a dated record?
Short answer
Start with the date required by the document or policy: invoice date for invoice recognition, payment date for cash settlement, or reporting date for period-end measurement. If the selected date has no published reference point, record the latest available business-day date rather than silently relabeling it.
A practical method for choosing an invoice date, payment date, reporting date, or latest available business-day reference rate.

No. The correct date depends on the applicable policy, contract, and reporting purpose.
Should the retrieval date be saved?
Yes. Saving both the rate date and retrieval date makes later review easier.
