Wrapper Methods

Candle retrieval is handled by two methods

GetHistoricCandles which makes a single request to the exchange and follows all exchange limitations

func (b *base) GetHistoricCandles(ctx context.Context, pair currency.Pair, a asset.Item, start, end time.Time, interval kline.Interval) (kline.Item, error) {
	return kline.Item{}, common.ErrFunctionNotSupported
}

GetHistoricCandlesExtended that will make multiple requests to an exchange if the requested periods are outside exchange limits

func (b *base) GetHistoricCandlesExtended(ctx context.Context, pair currency.Pair, a asset.Item, start, end time.Time, interval kline.Interval) (kline.Item, error) {
	return kline.Item{}, common.ErrFunctionNotSupported
}

both methods return kline.Item{}

// Item holds all the relevant information for internal kline elements
type Item struct {
	Exchange string
	Pair     currency.Pair
	Asset    asset.Item
	Interval Interval
	Candles  []Candle
}

// Candle holds historic rate information.
type Candle struct {
	Time   time.Time
	Open   float64
	High   float64
	Low    float64
	Close  float64
	Volume float64
}

DBSeed helper

A helper tool cmd/dbseed has been created for assisting with candle data migration
