Types ¶

type CandlePrice ¶

type CandlePrice struct {
	Price     sdk.Dec // last trade price
	Volume    sdk.Dec // volume
	TimeStamp int64   // timestamp
}

CandlePrice defines price, volume, and time information for an exchange rate.

func NewCandlePrice ¶

func NewCandlePrice(provider, symbol, lastPrice, volume string, timeStamp int64) (CandlePrice, error)

NewCandlePrice parses the lastPrice and volume to a decimal and returns a CandlePrice

type CurrencyPair ¶

type CurrencyPair struct {
	Base  string
	Quote string
}

CurrencyPair defines a currency exchange pair consisting of a base and a quote. We primarily utilize the base for broadcasting exchange rates and use the pair for querying for the ticker prices.

func MapPairsToSlice ¶

func MapPairsToSlice(mapPairs map[string]CurrencyPair) []CurrencyPair

MapPairsToSlice returns the map of currency pairs as slice.

func (CurrencyPair) String ¶

func (cp CurrencyPair) String() string

String implements the Stringer interface and defines a ticker symbol for querying the exchange rate.

type TickerPrice ¶

type TickerPrice struct {
	Price  sdk.Dec // last trade price
	Volume sdk.Dec // 24h volume
}

TickerPrice defines price and volume information for a symbol or ticker exchange rate.

func NewTickerPrice ¶

func NewTickerPrice(provider, symbol, lastPrice, volume string) (TickerPrice, error)

NewTickerPrice parses the lastPrice and volume to a decimal and returns a TickerPrice
