Applying Corrective AI to Daily Seasonal Forex Trading

  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

Are flash orders really so bad?

I confess I don't know much about flash orders, not being one of the Big Boys on the Street, until I read that the SEC is banning them . (For a clear diagrammatic explanation of flash orders, see here . For a refutation of some of the myths and misunderstanding surrounding flash orders, see here .) It seems to me that flash orders can be understood as "request for liquidity" issued to various potential market makers/liquidity providers, not unlike the usual "request for quotes" (RFQ) common in other industries. They are issued when there is not enough liquidity on a specific exchange to satisfy an investor's need, and they ultimately benefit investors by lowering their transaction costs. The fact that high frequency traders are able to make lots of money by providing this liquidity is besides the point. Liquidity providers are supposed to make money by providing liquidity! Some people, including Senator Charles Schumer and this New York Times op-ed , believe

Can a trader be a do-gooder?

It occurs to me that the only way in which a trader can become more than a completely selfish, self-enriching, narcissistic person is to trade well enough so that you can manage other people's money and thus saving these investors from crooks and charlatans (provided you are convinced you are not a crook and charlatan yourself). Other traders have advanced other arguments in favor of trading. But I am not convinced by them. They say that we provide liquidity to other long-term investors who may need to liquidate their investments. But then, this applies only to mean-reversal strategies. Momentum strategies take away liquidity from the market, and in some cases exacerbating price bubbles. Certainly not something your grandma would approve. Others argue that momentum strategies help disseminate information about companies through quick price movements. But can't we just watch Bloomberg or CNBC? Do we really need some devious insiders to convey that information to the rest of us t

Have you traded 10,000 hours yet?

Author Malcolm Gladwell, in his fascinating bestseller " Outliers: The Story of Success ", cites neurological research showing that "10,000 hours of practice is required to achieve the level of mastery associated with being a world-class expert." This seems to apply across many different types of experts, whether they are "writers, ice skaters, concert pianists, chess players ... Even Mozart ... couldn't hit his stride until he had his ten thousand hours in". Reflecting on my own experience, I have become consistently profitable only after 4 years of actual trading (research alone doesn't count -- real money need to be at risk.) So while the number of hours may not be exactly 10,000, the order of magnitude is about right. So if your trading has not been profitable, ask yourself this: "Have I traded 10,000 hours yet?"
