-Description:
- This high-level API client offers a streamlined access to public cryptocurrency market data and sentiment indicators. It features OHLC-V (Open, High, Low, Close, Volume) that comes
- with granularity ranging from seconds to months and essential sentiment indicators to develop and backtest trading strategies, or conduct detailed market analysis. By interacting directly with
- the major cryptocurrency exchanges this package ensures a reliable, and stable, flow of market information, eliminating the need for complex, low-level API interactions or webcrawlers.
+Description:
+ This high-level API client provides open access to cryptocurrency market data, sentiment indicators, and interactive charting tools.
+ The data is sourced from major cryptocurrency exchanges via 'curl' and returned in 'xts'-format. The data comes in open, high, low, and close (OHLC) format with flexible granularity, ranging from seconds to months.
+ This flexibility makes it ideal for developing and backtesting trading strategies or conducting detailed market analysis.

-# cryptoQuotes 1.3.1
+# Version 1.3.2
+
+## General
+
+* `bitmart` has updated their futures API. The backend have been updated accordingly.
+
+* Unit-tests have been updated and now all `get_quote()`-functions are being tested for equality in passed and inferred interval.
+
+## Improvements
+
+## Read and Write `xts`-objects
+
+* `read_xts()` and `write_xts()` reads and stores `xts`-objects. These functions are essentially just wrappers of `zoo::read.zoo()` and `zoo::write.zoo()`. Thank you @gokberkcan7 for the suggestion.
+
+### Charting
+
+* The `chart()`-function are now exported as `.svg`-images in 4k resolution via the `modebar`.
+* The `chart()`-function are now more interactive and supports drawing lines and rectangles via the `modebar`. It is also possible to interactively change the `title` and `subtitle` by double clicking these (Thank you @andreltr for the suggestion. See [Discussion](https://github.com/serkor1/cryptoQuotes/discussions/19)).
+* The `chart()`-function now has a new option `static` that is equal to `FALSE` by default. If `FALSE` the chart can be edited, annotated and explored interactively.
+* The `chart()`-function now has a new option `palette` that is set to "hawaii" by default. See `hcl.pals()` for accepted values.
+* The `chart()`-function now has a new option `scale` that is set to 1 by default. Scales all fonts on the chart.
+* The `chart()`-function now has a new option `width` that is set to 0.9 by default. Sets the overall `linewidth` of the chart. (Thank you @andreltr for the suggestion. See [Discussion](https://github.com/serkor1/cryptoQuotes/discussions/30))
+
+
+Static set to FALSE (Default Palette)
+```{r}
+# static = FALSE

+
+
+### Supported Exchanges (Issue [#14](https://github.com/serkor1/cryptoQuotes/issues/14))
+
+[{cryptoQuotes}](https://serkor1.github.io/cryptoQuotes/) now supports the following exchanges:
+
+* Crypto.com
+* Huobi
+* MEXC
+
+
+## Breaking Changes
+
+## Bugfixes
+
+### Charting
+
+* Fixed a bug in the `chart()`-function where a warning would be given if called using namespace qualified function calls (Issue [#13](https://github.com/serkor1/cryptoQuotes/issues/13))
+* Fixed a bug in the `chart()`-function where a `legend` wouldn't show unless a main-chart indicator
+were included. (Issue [#13](https://github.com/serkor1/cryptoQuotes/issues/13))
+
+### Quotes
+
+* Removed `1s` from *Binance spot*
+* Removed `3m`, `6h` and `3d` in *Bitmart spot*
+
+These intervals have been removed as they have either been discontinued, or were non-existent.

+In this `vignette` an introduction to the construction of charts and chart indicators are given, and is recommended for those who would want to chart indicators not otherwise found in [{cryptoQuotes}](https://serkor1.github.io/cryptoQuotes/). The `vignette` uses the built-in `BTC`-object.

-## Charting indicators
+As the charts in [{cryptoQuotes}](https://serkor1.github.io/cryptoQuotes/) uses [{plotly}](https://github.com/plotly) as backend, the `chart`-objects complies with it's syntax.
-Below is a chart, with the indicators `macd()` and `bollinger_bands()`. Each indicator is created using the `TTR`-package.
+## Custom Indicators
+
+We start by creating a simple `chart`-object with `volume` as it's only indicator,
```{r}
-chart(
- ticker = BTC,
- main = kline(),
- sub = list(
- macd()
+# 1) create a simple chart
+# object
+#
+# NOTE: The chart is wrapped in
+# plotly::layout() to avoid
+# duplicating xaxis when the
+# custom indicators are added
+chart_object <- plotly::layout(
+ chart(
+ ticker = BTC,
+ main = kline(),
+ sub = list(
+ volume()
),
- indicator = list(
- bollinger_bands()
- )
-)
-```
-
-### The anatomy of indicators
-
-Each indicator is either a *main chart*- or *subchart*-indicator, lets call them `classes` for consistency. The source code for each `class` of indicator is given below,
-
-
-Main chart indicator (Bollinger Bands)
-```{r, echo=FALSE}
-bollinger_bands
-```
-
-
-
-Subchart indicator (MACD)
-```{r, echo=FALSE}
-macd
-```
-
-
-Common for both indicator `classes` is that they are wrapped in `structure`, with `class = c("plotly", "htmlwidget")`,
-
-```R
-structure(
- .Data = {
-
- # Indicator Logic
-
- },
- class = c(
- yourclass,
- "plotly",
- "htmlwidget"
+ options = list(
+ dark = FALSE
+ )
+ ),
+ xaxis = list(
+ showticklabels = FALSE
)
)
```
-What differentiates the two `classes` of indicators, is the addition of `indicator` or `subchart` in the `yourclass`-placeholder.
-
-The indicator logic is important for the correct charting of your custom indicator. As the `cryptoQuotes`-package uses `plotly` as backend for charting, your `class` of indicator has to be consistent with the use of `plotly`-functions. More specifically; `subchart`-indicators uses `plotly::plot_ly()`-functions, while main chart `indicator` uses `add_*`-functions.
+### Sine-oscillator
-When creating the custom indicators there is a couple of additional steps needed which will be covered in the examples.
-
-## Donchian Channels (Example)
-
-Assume a trading strategy based on Donchian Channels (`TTR::DonchianChannel()`) is needed to optimize your profits. This indicator is a main chart indicator, similar to that of `TTR::BBands()`,
+Assume a trading strategy that follows a `sin()`-curve throughout the period of interest. The starting point is generating the indicator,
```{r}
-tail(
- TTR::DonchianChannel(
- HL = BTC[,c("high", "low")]
- )
+# 1) generate sin-indicator
+sin_indicator <- data.frame(
+ index = zoo::index(BTC),
+ sin_indicator = sin(seq(0,8*pi,length.out=nrow(BTC)))
+
)
```
-This indicator has three features; `high`, `mid` and `low`. To chart this indicator, we would need to call the `plotly::add_lines()`-function three times to chart it properly. Each of these features are defined as `layers` in the `cryptoQuotes`-package. All layers get built with the `cryptoQuotes:::build()`-function.
+The `sin_indicator` in it's basic form can be charted as follows,
```{r}
-## define custom TA
-## donchian_channel
-donchian_channel <- function(
- ## these arguments are the
- ## available arguments in the TTR::DonchianChannel
- ## function
- n = 10,
- include.lag = FALSE,
- ## the ellipsis
- ## is needed to interact with
- ## the chart-function
- ...
-) {
-
- structure(
- .Data = {
-
- ## 1) define args
- ## as a list from the ellipsis
- ## which is how the chart-function
- ## communicates with the indicators
- args <- list(
- ...
- )
-
- ## 2) define the data, which in this
- ## case is the indicator. The indicator
- ## function streamlines the data so it works
- ## with plotly
- data <- cryptoQuotes:::indicator(
- ## this is just the ticker
- ## that is passed into the chart-function
- x = args$data,
-
- ## columns are the columns of the ohlc
- ## which the indicator is calculated on
- columns = c("high", "low"),
-
- ## the function itself
- ## can be a custom function
- ## too.
- .f = TTR::DonchianChannel,
-
- ## all other arguments
- ## passed into .f
- n = n,
- include.lag = FALSE
- )
-
- ## each layer represents
- ## each output from the indicator
- ## in this case we have
- ## high, mid and low.
- ##
- ## The lists represents a plotly-function
- ## and its associated parameters.
- layers <- list(
- ## high
- list(
- type = "add_lines",
- params = list(
- showlegend = FALSE,
- legendgroup = "DC",
- name = "high",
- inherit = FALSE,
- data = data,
- x = ~index,
- y = ~high,

- )
- )
- ),
-
- ## mid
- list(
- type = "add_lines",
- params = list(
- showlegend = FALSE,
- legendgroup = "DC",
- name = "mid",
- inherit = FALSE,
- data = data,
- x = ~index,
- y = ~mid,
- line = list(

-
- ## we can add ribbons
- ## to the main plot to give
- ## it a more structured look.
- plot <- plotly::add_ribbons(
- showlegend = TRUE,

+# 1) create a plotly-object

+sin_indicator <- plotly::layout(

+# 2) display the

```
-The indicator function can be passed into the appropriate argument in the `chart()`-function, which will handle everything else,
+The `sin_indicator` can be added to the `chart_object` using `plotly::subplot` which also handles the theming,
```{r}
-chart(
- ticker = BTC,
- main = kline(),
- sub = list(
- volume()
+# 1) append the sin_indicator
+# to the chart object
+chart_object <- plotly::subplot(
+ # ensures that plots are
+ # vertically aligned
+ nrows = 2,
+ heights = c(
+ 0.7,
+ 0.2
),
- indicator = list(
- bollinger_bands(),
- donchian_channel()
- )
+ chart_object,
+ sin_indicator,
+ shareX = FALSE,
+ titleY = FALSE
)
+
+# 2) display the chart
+# object
+chart_object
```
-## Commodity Channel Index (Example)
+### Linear Regression Line
-Assume a trading strategy based on Commodity Channel Indices (`TTR::CCI()`) is needed to optimize your profits. This indicator is subchart indicator similar to that of `TTR::RSI()`,
+Assume a trading strategy that goes long (short) every time the price is below (above) the linear regression line. This indicator can be defined as follows,
```{r}
-tail(
- TTR::CCI(
- HLC = BTC[,c("high", "low", "close")]
- )
+# 1) linear regression
+# line
+lm_indicator <- data.frame(
+ y = fitted(
+ lm(
+ close ~ time,
+ data = data.frame(
+ time = 1:nrow(BTC),
+ close = BTC$close
+ )
+ )
+ ),
+ index = zoo::index(BTC)
)
```
-This indicator has a single feature; `cci`. As this indicator is a subchart indicator with a single feature, we only need a single `layer` built with `plot_ly()`,
-
+The `lm_indicator` in it's basic form can be charted as follows,
```{r}
-## define custom TA
-## Commodity Channel Index (CCI)
-cc_index <- function(
- ## these arguments are the
- ## available arguments in the TTR::CCI

## Summary
-Creating custom indicators for the `chart()`-functions can be daunting. Two examples of how these are developed in th e `cryptoQuotes`-packages have been covered.
+Creating custom indicators for the `chart()`-functions follows standard [{plotly}](https://github.com/plotly) syntax. Two examples of how these are charted in [{cryptoQuotes}](https://serkor1.github.io/cryptoQuotes/) have been covered.
> **Note:** A full pipeline of charting indicators, custom and built-in, will be released sometime in the future.
-
-To summarise the example,
-
-1. Define the `indicator`-function (e.g `TTR::CCI()`)
-2. Define the `chart`-function for the indicator (e.g `cc_index()`)
- 1. Wrap the `indicator`-function in `cryptoQuotes:::indicator()`
- 2. Define the `layers` according to features, and wether its a subchart or main chart indicator
- 3. Build the chart using `cryptoQuotes:::build()`
-3. Add the `chart`-function for the indicator in the appropriate argument in the `chart()`-function
