## Wrapper Methods
Candle retrieval is handled by two methods
GetHistoricCandles which makes a single request to the exchange and follows all exchange limitations
```go
func (b *base) GetHistoricCandles(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
```go
func (b *base) GetHistoricCandlesExtended(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{}
```go
// 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
}
```
