public final class CurrencyBuy
extends APIServlet.APIRequestHandler

Buy currency for NXT

Parameters

• currency - currency id
• rateNQT - exchange rate between NXT amount and currency units
• units - number of units to buy

currency buy transaction attempts to match existing exchange offers. When a match is found, the minimum number of units between the number of units offered and the units requested are exchanged at a rate matching the highest sell offer
A single transaction can match multiple sell offers or none. Unlike asset bid order, currency buy is not saved. It's either executed immediately (fully or partially) or not executed at all. For every match between buyer and seller an exchange record is saved, exchange records can be retrieved using the GetExchanges API
