getCommoditiesAndDateRange :: [Text] -> FilePath -> IO ([CommoditySymbol], Day, Day) Source #
Given a list of Commodities to exclude and a Journal File, return the Commodities in the Journal and the minimum/maximum days from the Journal.
Arguments
| :: Config | AlphaVantage Configuration |
| -> [CommoditySymbol] | Commodities to Fetch |
| -> [Text] | Commodities to Classify as Cryptocurrencies |
| -> Map Text Text | Map of aliases to transform journal commodities |
| -> Day | Start of Price Range |
| -> Day | End of Price Range |
| -> Bool | Rate Limit Requests |
| -> IO [(CommoditySymbol, [(Day, Prices)])] |
Fetch the Prices for the Commodities from the AlphaVantage API, limiting the returned prices between the given Days.
Note: Fetching errors are currently logged to stderr.
makePriceDirectives :: [(CommoditySymbol, [(Day, Prices)])] -> ByteString Source #
Build the Price Directives for the Daily Prices of the given Commodities.
unaliasAndBucketCommodities Source #
Arguments
| :: [CommoditySymbol] | Journal symbols |
| -> [Text] | Cryptocurrency symbols |
| -> Map Text Text | Aliases |
| -> ([CommoditySymbol], [CommoditySymbol]) |
Given a list of commodities from a journal, a list a cryptocurrencies, and a map of aliases, return the a list of AlphaVantage equities & cryptocurencies.
Arguments
| :: [(CommoditySymbol, a)] | Unaliased pairs of symbols |
| -> [CommoditySymbol] | Original symbols from the journal |
| -> Map Text Text | Aliases |
| -> [(CommoditySymbol, a)] |
Given a list of paired unaliased symbols, the original journal commodities, and the map of aliases, generate a new list of paired symbols that reflects the commodities in the original journal.
Pairs with symbols in the journal but not in the aliases will be unaltered. Pairs with aliases only in the journal will return only alias items. Pairs for multiple aliases with return a set of items for each alias. Pairs with symbols and aliases in the journal will return both sets of items.
