In bautheac/pullit: Pulling financial data from Bloomberg made easy

Description

Provided with a set of Bloomberg futures active contract tickers, term structure positions, roll parameters and a time period, retrieves the corresponding term structure historical data previously stored in a storethat SQLite database.

Usage

storethat_futures_TS(
  file,
  active_contract_tickers,
  start,
  end,
  TS_positions,
  roll_type,
  roll_days,
  roll_months,
  roll_adjustment,
  verbose
)

Arguments

file	a scalar chatacter vector. Specifies the target storethat SQLite database file.
active_contract_tickers	a chatacter vector. Specifies the futures active contract Bloomberg tickers to query data for.
start	a scalar character vector. Specifies the starting date for the query in the following format: 'yyyy-mm-dd'.
end	a scalar character vector. Specifies the end date for the query in the following format: 'yyyy-mm-dd'.
TS_positions	An integer vector. Specifies the term structure positions to query data for.
roll_type	a scalar chatacter vector. Specifies roll type to use for term structure ticker construction. Must be one of 'A', 'B', 'D', 'F', 'N', 'O' or 'R'.
roll_days	a scalar integer vector. Specifies the day the roll should be done. Refers to the day of the month (roll_type = 'F') or the number of days before a reference date (roll_type = 'D', roll_type = 'N', roll_type = 'O', roll_type = 'R'). Works in tandem with roll_months below.
roll_months	a scalar integer vector. Specifies the month the roll should be done. Refers to the number of months before a reference date (roll_type = 'D', roll_type = 'N', roll_type = 'O', roll_type = 'R'). Works in tandem with roll_days above.
roll_adjustment	a scalar chatacter vector. Specifies roll adjustment method to use for term structure ticker construction. Must be one of 'D', 'N', 'R', or 'W'.
verbose	a logical scalar vector. Should progression messages be printed? Defaults to TRUE.

Value

An S4 object of class FuturesTS.
