Efficient Estimation of Bid-Ask Spreads from Open, High, Low, and Close Prices
This repository implements an efficient estimator of the effective bid-ask spread from open, high, low, and close prices as described in:
Ardia, D., Guidotti, E., Kroencke, T.A. (2024). Efficient Estimation of Bid-Ask Spreads from Open, High, Low, and Close Prices. Journal of Financial Economics, 161, 103916. doi: 10.1016/j.jfineco.2024.103916
The estimator is available in:
| C++ | Julia | MATLAB | Python | R | SAS |
You can also check the pseudocode to implement the estimator in any programming language.
