CRAN release 1.3.0

ichimoku 1.3.0

New features:

• Sub-plots now feature on the same chart and values can be read via the infotip in iplot() or oanda_studio().
• R/S-type indicators now an option for oanda_chart() and oanda_studio().
• .ichimoku() introduced as a faster technical utility version of ichimoku() for use when data is already in the prescribed format.

Updates:

• 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.
• Fixes archive() to work correctly on R-oldrel (4.0).
• Further performance enhancements to ichimoku(), mlgrid() and plot functions.
• Documentation refresh.

CRAN release 1.2.5

ichimoku 1.2.5

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'.

Updates:

• 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.
• oanda_view() updated for new instruments and now returns correct data types in the dataframe.
• 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.

CRAN release 1.2.4

ichimoku 1.2.4

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 as.data.frame() implemented as a marginally faster version of xts_df() for ichimoku objects.
• More informative custom str() and summary() methods implemented for ichimoku objects.

Updates:

• 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.

CRAN release 1.2.2

ichimoku 1.2.2

New features:

• New oanda_quote() function outputs the latest quote for an instrument along with intraday trading statistics to the console.
• 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'.

Updates:

• 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

CRAN release 1.2.1

ichimoku 1.2.1

Updates:

• Fix issue with 'bslib' theming after release of Shiny 1.7.0. For improved reliability, 'bslib' optional dependency removed.
• More neutral formatting of oanda_stream() output to accommodate different console colour schemes.
• Fix cases of mis-alignment of main and sub-plots, axis label formatting of custom plots.
• Fix issue which caused iplot() to re-calculate the indicators when adjusting the data window.
• Package dependency switched from 'gridExtra' to 'gtable'.
• Minor performance improvements for ichimoku() and other functions.

ichimoku 1.2.0

New features:

• ichimoku() adds ability to create pseudo cloud charts from single series price data where OHLC data is not available.
• ichimoku() gains a 'keep.data' argument for retaining additional data present in the input object.
• 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.

Updates:

• 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.
