Show CandlestickGranularity

Methods

showsPrec :: Int -> CandlestickGranularity -> ShowS

show :: CandlestickGranularity -> String

showList :: [CandlestickGranularity] -> ShowS

ToJSON CandlestickGranularity

Methods

toJSON :: CandlestickGranularity -> Value

toEncoding :: CandlestickGranularity -> Encoding

toJSONList :: [CandlestickGranularity] -> Value

toEncodingList :: [CandlestickGranularity] -> Encoding

FromJSON CandlestickGranularity

Methods

parseJSON :: Value -> Parser CandlestickGranularity

granularityFromDiffTime :: NominalDiffTime -> Maybe CandlestickGranularity

granularityToDiffTime :: CandlestickGranularity -> NominalDiffTime

Utility function to convert Granularity to NominalDiffTime. NOTE: The conversion from month to NominalDiffTime is not correct in general; we just assume 31 days in a month, which is obviously false for 5 months of the year.
