The mid-market rates
shown in our information services are neither
"buy" rates nor "sell" rates. Mid-market
rates are derived from mid-point between the
buy and sell rates of large-value transactions
in the global currency markets.
Since "buy rates"
and "sell rates" include overheads and profit
margins that are set independently by each
foreign exchange provider, they will vary
depending on who you're talking to, and will
always be different than the mid-market rate.
