Functions

func BitfinexPriceFunction

func BitfinexPriceFunction(
	response *http.Response,
	tickerToExponent map[string]int32,
	resolver types.Resolver,
) (tickerToPrice map[string]uint64, unavailableTickers map[string]error, err error)

BitfinexPriceFunction transforms an API response from Bitfinex into a map of tickers to prices that have been shifted by a market specific exponent.

Types

type BitfinexTicker

type BitfinexTicker struct {
	Pair      string `validate:"required"`
	BidPrice  string `validate:"required,positive-float-string"`
	AskPrice  string `validate:"required,positive-float-string"`
	LastPrice string `validate:"required,positive-float-string"`
}

BitfinexTicker is our representation of the ticker information in Bitfinex API response. The raw response is a slice of floats. We use this constructed response to enable stricter validation. BitfinexTicker implements interface `Ticker` in util.go.
