Tennis (along with football) is one of the most popular sports for in-play trading. There is a wealth of freely available data for which to build trading models.
In-play trading allows the suitably equiped trader to watch and trade the changing fortunes of tennis players whilst matches are in progress.
These academic papers can be found on Google Scholar, JSTOR and in journals stored in university libraries. Some post graduate disertations are listed at the end.
