## 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(ctx context.Context, pair currency.Pair, a asset.Item, interval kline.Interval, start, end time.Time) (*kline.Item, error) {
|
|
return nil, common.ErrFunctionNotSupported
|
|
}
|
|
```
|
|
|
|
GetHistoricCandlesExtended that will make multiple requests to an exchange if the requested periods are outside exchange limits
|
|
```go
|
|
func (b *base) GetHistoricCandlesExtended(ctx context.Context, pair currency.Pair, a asset.Item, interval kline.Interval, start, end time.Time) (*kline.Item, error) {
|
|
return nil, 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
|
|
}
|
|
```
|
|
|
|
### DBSeed helper
|
|
|
|
A helper tool [cmd/dbseed](../cmd/dbseed/README.md) has been created for assisting with candle data migration
