Functions ¶
func GetAllSecurityList ¶
GetAllSecurityList gets all the security identifiers and descriptions
Example ¶
identifier, description := GetAllSecurityList()
fmt.Printf("len(identifier)=%v\n%q : %q\n", len(identifier), identifier[20000], description[20000])
Output: len(identifier)=21382 "GOOG/NYSEARCA_TDTT" : "TDTT"
func GetBitcoinList ¶
GetBitcoinList just returns http://www.quandl.com/api/v1/datasets/BITCOIN/BITSTAMPUSD
func GetCommoditiesList ¶
GetCommoditiesList gets all the Quandl codes and commodity descriptions
func GetETFList ¶
GetETFList gets all the Quandl codes and ETF descriptions
func GetETFTickerList ¶
GetETFTickerList gets all the Quandl codes and ETF tickers
func GetEconomicDataList ¶
Economic data (doesn't pertain to a particular security) GetEconomicDataList
Example ¶
identifier, description := GetEconomicDataList()
fmt.Printf("%q : %q\n", identifier[0], description[0])
Output: "FRED/LAWFIN" : "Finance and Insurance Wages and Salaries in Louisiana"
func GetFTSE100Constituents ¶
GetFTSE100Constituents
func GetFinancialRatiosList ¶
GetFinancialRatiosList returns the list of Damordoran financial ratios. Currently this list is hard-coded into the file because Quandl does not provide a file from where to read. A caveat about using these is that you need to append the ticker in a particular way to use these ratios
Example ¶
identifier, description := GetFinancialRatiosList()
fmt.Printf("%q : %q\n", identifier[10], description[10])
Output: "PE_FWD" : "Forward PE Ratio"
func GetNasdaq100Constituents ¶
GetNasdaq100Constituents
func GetNasdaqCompositeConstituents ¶
GetNasdaqCompositeConstituents
func GetSP500Constituents ¶
Index membership GetSP500Constituents
Example ¶
identifier, description := GetSP500Constituents()
fmt.Printf("len(identifer)=%v\n", len(identifier))
fmt.Printf("len(description)=%v\n", len(description))
//fmt.Printf("%q : %q\n", identifier[0], description[0])
Output: len(identifer)=500 len(description)=500
func GetSP500SectorMappings ¶
Sector mappings GetSP500SectorMappings
Example ¶
identifier, description := GetSP500SectorMappings()
fmt.Printf("len(identifer)=%v\n", len(identifier))
fmt.Printf("len(description)=%v\n", len(description))
//fmt.Printf("%q : %q\n", identifier[0], description[0])
Output: len(identifer)=500 len(description)=500
func GetStockIndexList ¶
GetStockIndexList gets all the Quandl codes and stock index descriptions
func GetStockList ¶
GetStockList gets all the Quandl stock codes and descriptions
Example ¶
identifier, description := GetStockList()
fmt.Printf("%q : %q\n", identifier[0], description[0])
Output: "WIKI/ACT" : "Actavis, Inc."
func GetStockTickerList ¶
GetStockTickerList gets all the Quandl codes and tickers
func Search ¶
Search executes a query against the Quandl API and returns the JSON object as a byte stream. In future releases of this Go (golang) Quandl package this will return a native object instead of the json
func SetAuthToken ¶
func SetAuthToken(token string)
SetAuthToken sets the auth token globally so that all subsequent calls that retrieve data from the Quandl API will use the auth token.
Example ¶
SetAuthToken("")
x, _ := GetData("WIKI/AAPL", "2013-01-01", "2013-01-05")
x.ToDate = "2014-05-22"
fmt.Printf("%s\n", x)

Types ¶
type QuandlResponse ¶
type QuandlResponse struct {
SourceCode string `json:"source_code"`
SourceName string `json:"source_name"`
Code string `json:"code"`
Frequency string `json:"frequency"`
FromDate string `json:"from_date"`
ToDate string `json:"to_date"`
Columns []string `json:"column_names"`
Data interface{} `json:"data"`
}
func GetAllHistory ¶
func GetAllHistory(identifier string) (*QuandlResponse, error)
GetAllHistory is similar to GetData except that it does not restrict a date range
Example ¶
x, _ := GetAllHistory("DMDRN/MSFT_MKT_CAP")
fmt.Printf("%s\n", x)
Output: &{DMDRN Damodaran Financial Data MSFT_MKT_CAP annual 2000-06-30 2013-06-30 [Date Market Capitalization] [[2013-06-30 %!s(float64=312297.5)] [2012-06-30 %!s(float64=227057.1)] [2011-06-30 %!s(float64=217062.1)] [2010-06-30 %!s(float64=241362.8)] [2009-06-30 %!s(float64=275188)] [2008-06-30 %!s(float64=172089.1)] [2007-06-30 %!s(float64=336499.4)] [2006-06-30 %!s(float64=294403.6)] [2005-06-30 %!s(float64=280921.5)] [2004-06-30 %!s(float64=292811.8)] [2003-06-30 %!s(float64=293355.8)] [2002-06-30 %!s(float64=300819.4)] [2001-06-30 %!s(float64=364524.4)] [2000-06-30 %!s(float64=281947.4)]]}
func GetData ¶
func GetData(identifier string, startDate string, endDate string) (*QuandlResponse, error)
GetData gets Quandl data for a particular identifier and a date range. You can optionally set the auth token before running this function so that you can make unlimited API calls instead of being limited to 500/day.
func (*QuandlResponse) GetTimeSeries ¶
func (q *QuandlResponse) GetTimeSeries(column string) ([]string, []float64)
GetTimeSeries returns a date vector and the value vector for a particular column in the QuandlResponse
func (*QuandlResponse) GetTimeSeriesColumn ¶
func (q *QuandlResponse) GetTimeSeriesColumn(column string) []float64
GetTimeSeriesColumn returns the data from the Quandl response for a particular column. For some series, particularly stock data, multiple columns are returned. Using this method you can specify the specific column to extract.
func (*QuandlResponse) GetTimeSeriesData ¶
func (q *QuandlResponse) GetTimeSeriesData() ([]float64, string)
GetTimeSeriesData returns the most relevant data column from the Quandl response. In many cases you will not necessarily know beforehand what type of data is being requested and therefore cannot determine if it's stock data vs. economic data. In such cases, you can use this function to grab the column that is most likely relevant. The method also returns the most relevant
func (*QuandlResponse) GetTimeSeriesDate ¶
func (q *QuandlResponse) GetTimeSeriesDate() []string
GetTimeSeriesDate returns the series of dates in the time series
