cryptoQuotes: Cryptocurrency Market Data in R

What happens when Elon Musk Tweets about Dogecoin?

library(cryptoQuotes)

Introduction

This high-level API-client provides open access to cryptocurrency market data without relying on low-level coding and API-keys. Currently all actively traded cryptocurrencies on either binance, bybit, bitmart, kucoin and kraken are available.

In this vignette we will explore a case study to showcase the capabilities of the cryptoQuotes-package; how did the Dogecoin-market react to Elon Musks following tweet,

Cryptocurrency Market Analysis in R

Elon Musk tweeted (Well, now he X’ed) about Dogecoin January 14, 06.18 AM (UTC) - and Dogecoin rallied. To determine how fast the markets reacted to his tweets, we could get the market data for Dogecoin in 1 minute intervals the day he tweeeted using the getQuotes(),

## DOGEUSDT the day
## of the tweet on the
## 1m chart
DOGE <- cryptoQuotes::get_quote(
  ticker   = 'DOGE-USDT',
  interval = '1m',
  source   = 'kucoin',
  futures  = FALSE,
  from     = '2022-01-14 07:00:00',
  to       = '2022-01-14 08:00:00'
)

This returns an object of class xts and zoo with 61 rows. To calculate the rally within the first minute of the tweet, we can use xts-syntax to determine the how much it rallied,

## extrat the
## tweet moment
tweet_moment <- DOGE["2022-01-14 07:18:00"]

## calculate 
## rally
cat(
  "Doge closed:", round((tweet_moment$close/tweet_moment$open - 1),4) * 100, "%"
)
#> Doge closed: 8.02 %

Dogecoin rallied 8.02% within the minute Elon Musk tweeted.

Charting price action with candlesticks

We can illustrate this with candlestick charts using the chart()- and kline()-function,

## chart the
## price action
## using klines
cryptoQuotes::chart(
  ticker     = DOGE,
  main       = cryptoQuotes::kline(),
  sub  = list(
    cryptoQuotes::volume()
  ),
  options = list(
    dark = FALSE
  )
)

Charting price action with event lines

To create a, presumably, better visual overview we can add event lines using the event_data-argument, which takes a data.frame of any kind as argument,

## 1) create event data.frame
## by subsetting the data
event_data <- as.data.frame(
  zoo::coredata(
    DOGE["2022-01-14 07:18:00"]
  )
)

## 1.1) add the index 
## to the event_data
event_data$index <- zoo::index(
  DOGE["2022-01-14 07:18:00"]
)

# 1.2) add event label
# to the data
event_data$event <- 'Elon Musk Tweets'

# 1.3) add color to the
# event label
event_data$color <- 'steelblue'

This event data, can be passed into the chart as follows,

## 1) create event data.frame
## by subsetting the data
event_data <- as.data.frame(
  zoo::coredata(
    DOGE["2022-01-14 07:18:00"]
  )
)

## 1.1) add the index 
## to the event_data
event_data$index <- zoo::index(
  DOGE["2022-01-14 07:18:00"]
)

# 1.2) add event label
# to the data
event_data$event <- 'Elon Musk Tweets'

# 1.3) add color to the
# event label
event_data$color <- 'steelblue'

## 1) chart the
## price action
## using klines
cryptoQuotes::chart(
  ticker     = DOGE,
  event_data = event_data,
  main       = cryptoQuotes::kline(),
  sub  = list(
    cryptoQuotes::volume()
  ),
  options = list(
    dark = FALSE
  )
)
