midpointCandles :: OandaEnv -> InstrumentText -> CandlesArgs -> IO (Vector MidpointCandlestick) Source #
Retrieve the price history of a single instrument in midpoint candles

bidaskCandles :: OandaEnv -> InstrumentText -> CandlesArgs -> IO (Vector BidAskCandlestick) Source #
Retrieve the price history of a single instrument in bid/ask candles
data Granularity Source #

granularityToDiffTime :: Granularity -> NominalDiffTime Source #
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.
