By Sergei Belov, Ernest Chan, Nahid Jetha, and Akshay Nautiyal ABSTRACT We applied Corrective AI (Chan, 2022) to a trading model that takes advantage of the intraday seasonality of forex returns. Breedon and Ranaldo (2012) observed that foreign currencies depreciate vs. the US dollar during their local working hours and appreciate during the local working hours of the US dollar. We first backtested the results of Breedon and Ranaldo on recent EURUSD data from September 2021 to January 2023 and then applied Corrective AI to this trading strategy to achieve a significant increase in performance. Breedon and Ranaldo (2012) described a trading strategy that shorted EURUSD during European working hours (3 AM ET to 9 AM ET, where ET denotes the local time in New York, accounting for daylight savings) and bought EURUSD during US working hours (11 AM ET to 3 PM ET). The rationale is that large-scale institutional buying of the US dollar takes place during European working hours to pa

Studies (from Deustche Bank and Rice University among others) show estimates from Estimize are more accurate than estimates from traditional sell-side analysts. The first strategy we tested is a mean reversion strategy developed by the quantitative research team from Deltix using Estimize’s data. This strategy is based on the idea that post-earning-announcement prices typically revert from the short-term trend driven by the more recent Estimize estimates just before the announcement. We backtested this strategy with S&P100 over the period between 2012/01/01 and 2013/12/31. (Even though Estimize has 2014 data, we do not have the corresponding survivorship-bias-free price data from the Center for Research in Securities Prices that includes the closing bid
