Usecase

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,

Tweet by Elon Musk - the timezone is CET.

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: 8.71 %

Dogecoin rallied 8.71% within the minute Elon Musk tweeted.
