About

Maintained by Joshua UlrichCRAN page ↗GitHub ↗Issues ↗

A collection of over 50 technical indicators for creating technical trading rules. The package also provides fast implementations of common rolling-window functions, and several volatility calculations.

Changes in 0.24.4

Added Ethan B. Smith as a contributor. Thanks Ethan!

NEW FEATURES

Added a TR() function to calculate the true high, true low, and true range. Refactored ATR() to use the TR() function. Thanks to @openbmsjsc and Steve Bronder for the reports, and Ethan B. Smith for the PR. (#18, #114, #124)

BUG FIXES

Fix stockSymbols() for ticker "NA". read.table() converts the string "NA" to a missing value (NA) because na.strings = "NA" by default. This causes an issue because there's actually a company with "NA" for the ticker. (#128)
CTI() did not pad its result with leading NA when the input was not coerced to an xts object. This was different from other TTR functions (e.g. SMA(), RSI(), ROC()). (#127)

Show all changes in 0.24.4Hide the rest of the changes in 0.24.4

Removed the VMA() function, which was never correct because the results made no sense.
Check that the wma() C function has enough non-NA values and throw an error if it doesn't. This could cause the WMA() function to crash the user's R session. (#126)
runMean(..., cumulative = TRUE) didn't account for leading NA in the denominator. (#122)
runSD(x, cumulative = TRUE) returned all NA when x had any leading NA. Thanks to Ethan B. Smith for the report. (#121)
The TRIX() signal line did not use nSig unless maType was provided. Thanks to @SatoshiReport for the... report. (#120)

MISCELLANEOUS

Use symbols for native routine entry points to make them explicit and unable to be found accidentally. (#123)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("TTR", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("joshuaulrich/TTR")

Development version from joshuaulrich/TTR. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-ttr

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-TTR

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-TTR

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
