CRAN release: 2022-02-21

New features:
  • Dependency on C++ compiler, ‘cpp11’ and ‘gtable’ packages retired.
  • Internal rolling min/max/mean functions re-implemented directly in C; various ichimoku functions now call C code internally.
  • Added LinkingTo: xts for use of C function exported from ‘xts’.
  • df_trim() and extraplot() removed as no longer required.
  • The ‘limit’ argument for oanda_chart() and oanda_stream() changed to accept a time in seconds rather than minutes.
  • new.process = TRUE for oanda_studio() now more portable and works under Windows.
  • Fixes oanda_stream() for when multiple bid/ask liquidity levels are returned in the stream. Returned dataframe now in a revised tidier format with correct data types for ease of further processing.

  • Documentation refresh.

ichimoku 1.2.5

CRAN release: 2021-12-13

New features:
  • Enhancement to the printing of ichimoku objects by utilising the ‘tibble’ print method (adds dependency on ‘tibble’ package), paired with more() for quick printing of further rows.
  • Optimised as_tibble() method implemented for ichimoku objects.
  • mlgrid() now appends attributes ‘k’ and ‘type’ to returned objects, and gains the following arguments:
    • k to specify the k-period time horizon over which to calculate target variable ‘y’.
    • type = 'z-score' to produce the standard score of a ‘numeric’ type grid.
    • format to choose between returning a dataframe or matrix.
  • New oanda_orders() function provides the OANDA fxTrade order book for certain major currency pairs.
  • Major revamp of oanda_stream() which has a much improved interface and now renders the stream as a structured dataframe.
  • oanda_chart() and oanda_stream() gain the argument ‘limit’ which imposes a time limit for the session after which data is returned automatically.
  • oanda_positions() gains the parameter ‘time’ for retrieving the position book at a particular time.
  • archive() gains the ability to save files interactively using a system dialog - call the function with an object, leaving the second argument empty e.g. archive(object, ).
  • index() gains the parameter ‘subset’ for fast subsetting of ichimoku cloud indexes.
  • New plot themes ‘conceptual’ and ‘fresh’.
  • Simplification of look() by removing the ‘which’ argument. To extract ichimoku objects in autostrat lists, subset the list directly. The object argument is now optional, accessing .Last.value otherwise.
  • Minor enhancements to the str() method.
  • df_append() argument order for ‘old’ and ‘new’ swapped to allow for chaining with the pipe operator.
  • archive() now safe for use in non-interactive settings, where it no longer prompts to confirm overwriting of existing files.

  • Fixes cases of relative() showing the incorrect date for ‘latest’, along with other cosmetic changes.
  • General performance improvements to date handling and dataframe conversions.
  • Documentation refresh.

ichimoku 1.2.4

CRAN release: 2021-10-18

New features:
  • New relative() function produces a statistical summary of the latest ichimoku cloud chart numeric representation relative to historical values, for determining whether trading falls within or outside of normal ranges.
  • oanda_studio() gains the argument ‘new.process’, which when set to TRUE, starts the shiny session in a new R process, unblocking the current process and allowing continued use of the console.
  • mlgrid() gains the argument y = 'none' for a grid with the latest cloud representation and without ‘y’.
  • autostrat(), relative() and oanda() gain the argument ‘quietly’ which suppresses additional console output if set to TRUE.
  • Improved time index handling for ichimoku(): where conversion by as.POSIXct() fails, will convert numeric values as POSIX times (with an appropriate warning).
  • Optimised ‘ichimoku’ methods for coredata() and index() generic functions.
  • ‘ichimoku’ method for implemented as a marginally faster version of xts_df() for ichimoku objects.
  • More informative custom str() and summary() methods implemented for ichimoku objects.
  • For OANDA functions, where the ‘server’ parameter is specified, the corresponding API key will now be retrieved rather than the default, allowing for example oanda_studio(server = "live", new.process = TRUE)
  • Improved appearance of progress indicators for oanda() and oanda_view().
  • oanda() now safe to use non-interactively - it will no longer prompt in such cases.
  • Improvements to the visual appearance of oscillator plots.
  • Update to the interactive interface for oanda_set_key().
  • Fixes sign of %chg for oanda_quote().
  • xts() is no longer re-exported from the ‘xts’ package as ichimoku() can now fully re-construct an ichimoku object from its components (see ‘Working with ichimoku objects’ in the Reference vignette).
  • Further performance improvements to ichimoku() and other functions.
  • Documentation refresh.

  • New oanda_view() function provides the latest overview of an entire market - showing the relative performance of constituents.
  • New oanda_positions() function provides the OANDA fxTrade position book (% longs and shorts at each price level) for certain major currency pairs.
  • archive() now allows files to be chosen interactively using a system dialog - call the function with no arguments.
  • df_append() utility is now faster and gains the arguments ‘key’ and ‘keep.attr’.
  • Accessibility improvements: default ‘original’ theme adjusted to accommodate colour vision deficiency.
  • All OANDA functions now prompt for missing required arguments instead of returning errors.
  • For ease of use, the ‘instrument’ argument in all OANDA functions is now case-insensitive and the delimiter may be supplied as either ’_’ or ‘-’, so both oanda("usd-jpy") and oanda("USD_JPY") are acceptable.
  • tradingDays() argument ‘noholidays’ removed in favour of ‘holidays = NULL’. Logic changed slightly so that default holidays are applied only if ‘holidays’ is not specified.
  • Minor performance improvements to OANDA and ML layer functions.
  • Documentation refresh

ichimoku 1.2.1

CRAN release: 2021-09-23

  • Plot functions gain a ‘type’ argument to enable a choice of oscillator (R-type and S-type) to be shown as a sub-plot.
  • Plot functions gain a ‘custom’ argument to enable a custom data variable to be plot as a line or bar chart in the sub-plot area.
  • oanda_studio() adds a button for saving the underlying data of the live ichimoku cloud chart using archive().
  • oanda_chart() now returns the underlying ichimoku object (invisibly) on function exit, providing easy access to the chart data.
  • oanda_set_key() adds support for storing both practice and live account API keys.
  • New oanda_switch() function allows the default server to be switched from ‘practice’ to ‘live’ for the session.
  • Adds fallback for oanda_instruments() using an internal instruments table when the API call fails.
  • plot.ichimoku() now returns the original object invisibly, use autoplot() and extraplot() to return plot objects.
  • For all plot functions, the argument ‘message’ is renamed to ‘subtitle’.
  • Plots now show Tenkan-sen over Kijun-sen.
  • Slight adjustments to original theme: cloud edges now plum-tinted for Senkou A, cyan-tinted for Senkou B.

  • xts_df() and matrix_df() dataframe constructors gain a ‘keep.attrs’ argument. If set to TRUE, the returned dataframe will retain the custom attributes of the original object.

  • Implements caching of certain OANDA variables so that they are retrieved once and then used throughout a session.

  • strat() and autostrat() gain a new type/level 3 for asymmetric strategies using different indicators for position entry and exit.
  • New dependencies on ‘httr’ and ‘jsonlite’ packages, required for the OANDA fxTrade API interface.
