The aim of this paper is to evaluate the impact of temporary frequency data used for the calculation of moving averages on the implementation of active strategies. We analyze if the use of different frequency moving averages (1 and 15 minutes) have a significant impact on the yields earned with the investment technique. We analyze differences between yields of a passive strategy and yields obtained through a moving averages strategy. Finally, we compare the risk of an active strategy with that of a passive strategy.
