Note that there is no obligation to trade on a specific quoted price. An expression used in the traded markets to indicate that one does not want to trade at a quoted price is to say "nothing there."
Buying & Selling Currencies: Example
Let’s look at an example of a USD/CHF quote. In this case, USD is being traded, that is, USD is the base currency. Our “big figure” (or “handle”) is “88” – that is, the stem of the price quote. The full bid-offer figures are 0.8857/0.8860.
