Changes in 0.4-20 (2022-04-29)

1. Remove check for Yahoo Finance cookies because the site no longer responds with a cookie, and that caused the connection attempt to fail. This affected getSymbols(), getDividends(), and getSplits(). Thanks to several users for reporting, and especially to @pverspeelt and @alihru for investigating potential fixes! #358

2. Update getSymbols.yahooj() for changes to the web page. #312

3. Add HL() and supporting functions. These are analogues to HLC(), OHLC(), etc.Thanks for Karl Gauvin for the nudge to implement them.

4. Add adjusted close to getSymbols.tiingo() output. Thanks to Ethan Smith for the suggestion and patch! #289 #345

5. Use a Date index for getSymbols.tiingo() daily data. Thanks to Ethan Smith for the report! #350

6. Remove unneeded arguments to the getSymbols.tiingo() implementation. Thanks to Ethan Smith for the suggestion and patch! #343 #343

7. Load dividends and splits data into the correct environment when the user provides a value for the env argument. The previous behavior always loaded the data into the environment the function was called from. Thanks to Stewart Wright for the report and patch! #33

8. Make getOptionChain() return all the fields that Yahoo Finance provides. Thanks to Adam Childers (@rhizomatican) for the patch! #318 #336

11. Fix the getMetals() example in the documentation. The example section previously had an example of getFX(). Thanks to Gerhard Nachtmann

1. for the report and patch! #330

2. Fix getSymbols.yahoo(), getDividends(), and getSplits() so they all handle download errors and retry again. Thanks for @helgasoft for the report on getSymbols.yahoo() and @msfsalla for the report on getDividends() and getSplits(). #307 #314

Changes in 0.4-17 (2020-03-31)

Changes in 0.4-16 (2020-03-08)

1. Remove disk I/O from getSymbols() and getQuote(). This avoids any disk contention, and makes the implementation pattern more consistent with other functions that import data. Thanks to Ethan Smith suggestion and PR. #280 #281

2. Make getQuote() robust to symbols without data, so it does not error if one or more symbols are not found. Also return quotes in the same order as the ‘Symbols’ argument. Thanks to Ethan Smith feature request and PR. #279 #282 #288

3. Handle semicolon-delimited symbol string handling to main getQuote() function. This makes getQuote() consistent with getSymbols(). Thanks to Ethan Smith suggestion and PR. #284 #285

4. Fix ex-dividend and pay date mapping. getQuote() returned the dividend pay date labeled as the ex-dividend date. Thanks to @matiasandina for the report. #287

5. Fix Yahoo Finance split ratio. The delimiter changed from “/” to “:”. For example, a 2-for-1 split was 1/2 but is now “2:1”. Thanks to @helgasoft for the report. #292

6. Error messages from getQuote.alphavantage() and getQuote.tiingo() no longer contain the API key when symbols can’t be found. #286

Changes in 0.4-15 (2019-06-15)

1. Add an environment variable to control whether to run tests that import from Yahoo Finance. getDividends() tests were failing because Yahoo Finance wasn’t returning all dividend history for “CF”.
2. Write one message the first time quantmod::as.zoo.data.frame() is called. This method was added years before zoo::as.zoo.data.frame() existed, but it should be deprecated in favor of the zoo version. The package that owns the class should also own the methods.

1. Change maintainer from Jeffrey Ryan to Joshua Ulrich

2. Copy required functionality from the (archived) Defaults package into quantmod and remove dependency on Defaults.

3. Incorporate several bug fixes and patches.

Changes in 0.4-0

• getSymbols now uses parent.frame() when auto.assign=TRUE. This will cause slightly different behavior than previous versions using .GlobalEnv, but is more functional in design.

• getSymbols now allows for env=NULL, which will behave as if auto.assign=FALSE is set.

• Upcoming changes for version 0.5-0 will include deprecating auto assignment from within getSymbols calls. This will instead be moved to the loadSymbols function, to better match get/load behaviors in base R. For the transition, auto.assign will be available to force pre 0.5-0 behaviors, but will be discouraged. The env= arg will be used for multiple symbol assigns.

Changes in 0.3-7

• addTA now handles logical vectors or logical xtsible objects by drawing bands on chart window

• addTA can now draw on or under any window via ‘on=’ arg

• chartSeries now cleanly handles series without volume automatically

• addVo has new log.scale option

Changes in 0.3-6

MODIFICATIONS

• Delt (and functions that call) now defaults to ‘arithmetic’ (discrete) calculations vs. the previous behavior of ‘log’ (continuous) calculation. This is more inline with expected behavior

NEW FUNCTIONALITY

• addTA and newTA allow for dynamic indicator additions with little coding

Changes in 0.3-2

BUG FIXES

• matched broken TTR calls, aligned arguments between packages

• ‘name’ of chart was being evaluated somewhere in the process, resulting in the object becoming a string. Fixed in this release.

MODIFICATIONS

• continuing the move of time-series functionality to the ‘xts’ package

• added new TTR functions to addTA.

• added underlay charting to main area (BBands) as well as much more advanced shading and labeling.

• chartSeries converts incoming ‘x’ argument to xts object for more universal handling. Not fully sorted out - but better than before.

• new subset argument to allow for xts-style subsetting

NEW FUNCTIONALITY

• new TTR functions - ATR, CCI, CMF, CMO, DPO, Lines, Momentum, TRIX

Changes in 0.3-1

BUG FIXES

• new depends - on CRAN and R-Forge package xts for time-series handling internally

• options.expiry and futures.expiry now use universal %w to check weekdays

• Rmetrics change resulted in as.timeSeries moving to fSeries. New suggest and assoc. changes

MODIFICATIONS

• Added ability to plot series with missing values (like those in a ‘ts’ series) Volume with missing obs. is still broken - to be fixed in 0.3-2

Changes in 0.3-0

BUG FIXES

• Fixed factor bug in getSymbols.FRED. Thanks to Josh Ulrich

• Fixed bug in [.quantmod.OHLC method when i/j was missing, also now returns quantmod.OHLC object consistently

MODIFICATIONS

• Added high frequency data handling - to.minutes, to.hourly, to.daily. Additional work done to accomodate within rest of framework

• getSymbols downloads now to temp file - instead of directly to memory. Fixed R issue in certain Windows installations

• getSymbols now returns a character array of symbol names written to environment.

• getSymbols includes new arg - auto.assign. If set to FALSE will behave like standard R functions and simply return loaded object. Requires user assignment via ‘<-’

• Better handling of timeSeries, ts, its within entire package

NEW FUNCTIONALITY

• chartSeries rewrite. Now manages charting with S4 objects stored quietly in memory. Allowing for dynamic redraws used in applying technical indicators and overlays

• addTA functions. New charting tools to add technicals to charts dynamically. More on the way

• listTA, setTA, unsetTA to handle default TA args

• chartTheme function to customize chart ‘look’

• last/first functions now take character strings to describe in words the subsetting to do. Also negative value support for opposite behavior. Additional keep arg will assign removed data to an attribute keep with the object

• getSymbols.SQLite support. Still very clunky - though that is SQLite.

• getFX and getMetals for direct download of those types

• getQuote downloads Last,Change,Open,High,Low,Volume from Yahoo

• added documentation and fixed documentation
