map_bucket_trades {bitmexr}

Bucket trade data over an extended period

Description

map_bucket_trades() uses purrr::map_dfr to execute multiple API calls. This is useful when the data you want to return exceeds the maximum 1000 row response limit, but do not want to have to manually call bucket_trades() repeatedly.

Usage

map_bucket_trades(
  start_date = "2015-09-25 13:00:00",
  end_date = now(tzone = "UTC"),
  binSize = "1d",
  symbol = "XBTUSD",
  partial = "false",
  filter = NULL,
  use_auth = FALSE,
  verbose = FALSE
)

Arguments

start_date

character string. Starting date for results in the format "yyyy-mm-dd" or "yyyy-mm-dd hh-mm-ss".

end_date

character string. Ending date for results in the format "yyyy-mm-dd" or "yyyy-mm-dd hh-mm-ss".

binSize

character string. The time interval to bucket by, must be one of: "1m", "5m", "1h" or "1d".

symbol

a character string for the instrument symbol. Use available_symbols() to see available symbols.

partial

character string. Either "true" or "false". If "true", will send in-progress (incomplete) bins for the current time period.

filter

an optional character string for table filtering. Send JSON key/value pairs, such as "{'key':'value'}". See examples in trades().

use_auth

logical. Use TRUE to enable authentication with API key.

verbose

logical. If TRUE, will print information to the console. Useful for long running requests.

Details

map_bucket_trades() takes a start and end date, and creates a sequence of start dates which are passed in to the 'startTime“ parameter in bucket_trades().

The length of time between each start time in each API call is determined by the binSize. For example, "1d" is chosen as the binSize the length of time between start dates will be 1000 days. If "1h" is chosen, it will be 1000 hours etc.

The function will print the number of API calls being sent and provides a progress bar in the console

Public API requests are limited to 30 per minute. Consequently, map_bucket_trades() uses purrr::slowly to restrict how often the function is called.

• timestamp: POSIXct. Date and time of trade.
