1. Fix FRED URL. Thanks to Nicole Mirea (@nimirea) for the report! #439

2. Thanks to Michael Chirico for a couple PRs to handle some minor edge cases. #436, #437

3. Replace "YHOO" with "AAPL" where it is used in documentation, especially in examples. Thanks to @dougedmunds for the report! #435

4. Update getSymbols.csv() documentation to note that you have to set the format argument if the date in the CSV is not in a standard format. Thanks to @reddogg24 for the report that led to this change. #428

1. Reduce getQuote() batch size from 199 to 99. Yahoo started to throw an error for requests of 100 or more symbols at a time. Thanks to @zlfang00 for the report and Ethan B. Smith for the patch! #432, #433

2. Follow best practices by removing the encosing '{}' in setGeneric("fittedModel<-", ...). Thanks to Michael Chirico for the PR! #431

3. Improve detection of ambiguous 'OHLCVA' colnames in all extractor functions (e.g. Cl(), OHLC()). This is especially important for Lo() because quantmod::getSymbols("LOW") returns an object where every column name contains the pattern "LOW.". Another example is TTR::stoch(), which returns a column named "slowD". Thanks to Ethan B. Smith for the patch! #24, #305, #306, #426

4. Continue steps to remove quantmod:::as.zoo.data.frame() by throwing a warning every time quantmod::as.zoo.data.frame() is called. Previously a message was printed the first time the function was called. #414

5. Add ClOp() function to calculate the return between Close[t-1] and Open[t]. Thanks to Gabriel Kaiser (@GabrielKaiserQFin) for the contribution! #412

2. Fix getOptionChain.yahoo() by using the Yahoo Finance 'crumb' like we do in getSymbols() and getQuote(). Thanks to @cotyreh for the report. #407

1. Fix getQuote.yahoo() for API changes. Thanks to Ethan B. Smith for the report and patch! Also add error message for users in GDPR countries, since we cannot automatically consent to GDPR and the request fails without consent. #392 #393 #395

2. Fix getQuote.yahoo() when the user only requested metrics that do not have have a value for 'regularMarketTime'. Set the value to NA in these cases so the output remains the same regardless of whether the endpoint returns a 'regularMarketTime' or not. Thanks to @mehdiMBH for the report! #255

3. Add fields to getQuote.yahoo() that are returned when no fields are explicitly requested. Thanks to @Courvoisier13 for the report! #335

4. Add intraday endpoint to getSymbols.yahoo(). Thanks to @kapsner for the report and patch! Also allow suppressing the warning if more than 7 days of data are requested (@eddelbuettel). #351 #381 #399

5. Add warning if getSymbols() is called with tickers that are reserved words because accessing them requires back-quotes (e.g. NA). #401

6. Fix allReturns() when 'subset' is specified. Thanks to @Panagis1980 for the report! #402

https://github.com/joshuaulrich/quantmod - CRAN release 0.4.21

1. Fix S3 method issues. R-devel (83995-ish) added a check for possible S3 method issues. Register methods it found that were not registered: str.replot(), seriesHi.timeSeries(), and seriesLo.timeSeries().

   It was also confused by range.bars() and unique.formula.names(). Remove unique.formula.names() because it wasn't exported or used internally. Rename range.bars() to rangeBars(), which isn't exported.

   Thanks to Kurt Hornik for the report! #375

2. Remove "^" prefix from getSymbols() return value. When the 'Symbols' argument has a "^" prefix and auto.assign = TRUE: * getSymbols() removes the "^" from the object it creates, but * returns the 'Symbols' argument unchanged, and * removes the "^" from the column names of the object it creates.

   The example below will create an object named IXIC but the value of sym will be "^IXIC".

   sym <- getSymbols("^IXIC")
   

   That means x <- get(sym) will not work because an object named ^IXIC doesn't exist. #371

3. Add 'from' and 'to' arguments to getSymbols.FRED(). Users expect to be able to set the 'from' and 'to' arguments for FRED data like they can for Yahoo data. Those values were ignored and the entire series was always returned. #368

4. Change interval to 1d for getDividends() and getSplits(). The "3mo" setting caused some dividends to be missing for companies that issued monthly dividends. Note that the response to this request also includes all the OHLCV data. But it's small (less than 1MB for 60+ years of daily data). #372

5. Handle errors in getSplits() and getDividends(). getDividends() didn't handle cases where the download failed, or when dividends needed to be split-adjusted but there were no splits. It also tried to set colnames on the empty xts object that's returned when there are no dividends. getSplits() had the same colnames issue. Check for no splits by testing for NULL because that's more explicit. Thanks to Chris Cheung for the report! #366

6. Export HL(), is.HL(), and has.HL() functions and add documentation. These were added in 0.4.18 but not exported or included in the documentation.

7. Use Yahoo Finance v8 JSON endpoint and remove the v7 CSV endpoint. There seems to be a rate limit for the number of tickers you can request via the CSV endpoint. The yfinance python library uses the JSON endpoint and doesn't seem to have rate limit issues. #360, #362, #364

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

9. Add orats as a source for getOptionChain(). Thanks to Steve Bronder (@SteveBronder) for the suggestion and implementation! #325

10. Improve the error message when getSymbols() cannot import data for a symbol because the symbol is not valid or does not have historical data. Thanks to Peter Carl for the report. #333

11. Fix the getMetals() example in the documentation. The example section previously had an example of getFX(). Thanks to Gerhard Nachtmann (@nachti) for the report and patch! #330

12. Fix getQuote() so it returns data when the ticker symbol contains an "&". Thanks to @pankaj3009 for the report! #324

13. Fix addMACD() when col is specified. Thanks to @nvalueanalytics for the report! #321

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

3. Add implied volatility and last trade date to getOptionChain() output. Thanks to @hd2581 and @romanlelek for the reports. And thanks to @rjvelasquezm for noticing the error when lastTradeDate is NULL. #224 #304

4. Fix getOptionChain() to throw a warning and return NULL for every expiry that doesn't have data. #299

5. Add "Defaults" handling to getQuote() and getQuote.yahoo(). Thanks to @ethanbsmith for the report. #291

6. Add Bid and Ask fields to the output from getQuote(). Thanks to @jrburl for the report and PR. #302

7. Fix "Defaults" to handle unexported function (e.g. getQuote.av(). Thanks to @helgasoft for the report. #316

8. importDefaults() doesn't call get() on vector with length > 1. Thanks to Kurt Hornik for the report. #319

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
7. Fix getQuote.alphavantage() by replacing the defunct batch quote request with a loop over the single quote request. Thanks to @helgasoft for the report and patch. #296
8. Update getOptionChain() to handle empty volume or open interest Thank to @jrburl for the report and PR. #299

Changes

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.

2. Fix getQuote.yahoo() for quotes in multiple timezones. Thanks to Philippe Verspeelt for the report and PR. #246 #248

4. Fix futures.expiry(). Thanks to @pjheink for the report. #257
5. Fix getSymbols.tiingo() to return correct columns for ticker "LOW". Thanks to @srtg4we5gsetrgwhreyt the report. #259
6. Fix getSymbols.yahooj() to avoid infinite loop when the requested symbol doesn't have data. Thanks to Wouter Thielen for the review. #63
7. Update getSplits() because Yahoo Finance now provides the actual split adjustment ratio, instead of the inverse (e.g. now 1/2 instead of 2/1). #265

NEW FEATURES

1. Extend getQuote() to support Tiingo. Thanks to Ethan Smith for the feature request and PR. #247 #250
2. Extend getSymbols() to catch errors for individual ticker symbols and continue processing any remaining ticker symbols, instead of throwing an error. More useful error messages are also provided. Thanks to @helgasoft for testing and feedback. #135
