  The purpose of this research paper it is to present a new approach in the
framework of a biased roulette wheel. It is used the approach of a quantitative
trading strategy, commonly used in quantitative finance, in order to assess the
profitability of the strategy in the short term. The tools of backtesting and
walk-forward optimization were used to achieve such task. The data has been
generated from a real European roulette wheel from an on-line casino based in
Riga, Latvia. It has been recorded 10,980 spins and sent to the computer
through a voice-to-text software for further numerical analysis in R. It has
been observed that the probabilities of occurrence of the numbers at the
roulette wheel follows an Ornstein-Uhlenbeck process. Moreover, it is shown
that a flat betting system against Kelly Criterion was more profitable in the
short term.
