Why COP/USD Reference Rates Differ on Weekends
Reference rates, card-network rates and cash-counter offers may use different update schedules.
Understand the timestamp
An online currency feed may be delayed or based on its own market aggregation. Check when the displayed number was updated and the feed methodology.
Expect transaction spreads
The amount a service buys at and sells at can differ from a neutral reference midpoint; a fixed fee may also apply.
Watch the trade window
Currency markets do not all operate on the same schedule. A weekend transaction may be settled at a later rate depending on the provider.
Use the actual payout
For important transfers, compare the full amount received after provider charges rather than assuming that a single market-rate screenshot is executable.
How to use this guide
