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%.

library("bidask")
df = read.csv("https://raw.githubusercontent.com/eguidotti/bidask/main/pseudocode/ohlc.csv")
