In bidask: Efficient Estimation of Bid-Ask Spreads from Open, High, Low, and Close Prices

Efficient Estimation of Bid-Ask Spreads from Open, High, Low, and Close Prices

Implements an efficient estimator of bid-ask spreads from open, high, low, and close prices.

Installation

Install this package with:

install.packages("bidask")

Usage

Load the library:

library("bidask")

Arguments:

edge(open, high, low, close, sign=FALSE)

| field | description | | ------- | ------------------------------------------- | | open | Numeric vector of open prices | | high | Numeric vector of high prices | | low | Numeric vector of low prices | | close | Numeric vector of close prices | | sign | Whether signed estimates should be returned |

The input prices must be sorted in ascending order of the timestamp.

The output value is the spread estimate. A value of 0.01 corresponds to a spread of 1%.

Example

library("bidask")

df = read.csv("https://raw.githubusercontent.com/eguidotti/bidask/main/pseudocode/ohlc.csv")
edge(df$Open, df$High, df$Low, df$Close)
