The Retail FX Trader: Random Trading and the Negative Sum Game
With the internet boom of early 2000 making access to trading the Foreign Exchange (FX) market far simpler for members of the general public, the growth of 'retail' FX trading continues, with daily transaction volumes as high as $200 billion. Potential new entrants to the retail FX trading world may come from the recent UK pension deregulations, further increasing the volumes. The attraction of FX trading is that it offers high returns and whilst it has been understood that it is high-risk in nature, the rewards are seen as being commensurately high for the 'skilled and knowledgeable' trader who has an edge over other market participants. This paper analyses a number of independent sources of data and previous research, to examine the profitability of the Retail FX trader and compares the results with that of a simulated random trading models. This paper finds evidence to suggest that whilst approximately 20% of traders can expect to end up with a profitable account, around 40% might expect their account to be subject to a margin call. This paper finds a strong correlation between the overall profitability of traders and impact of the cost of the bid-ask spread, whilst finding little if any evidence that retail FX traders, when viewed as a group, are achieving results better than that from random trading
WATTNet: Learning to Trade FX via Hierarchical Spatio-Temporal Representation of Highly Multivariate Time Series
Finance is a particularly challenging application area for deep learning
models due to low noise-to-signal ratio, non-stationarity, and partial
observability. Non-deliverable-forwards (NDF), a derivatives contract used in
foreign exchange (FX) trading, presents additional difficulty in the form of
long-term planning required for an effective selection of start and end date of
the contract. In this work, we focus on tackling the problem of NDF tenor
selection by leveraging high-dimensional sequential data consisting of spot
rates, technical indicators and expert tenor patterns. To this end, we
construct a dataset from the Depository Trust & Clearing Corporation (DTCC) NDF
data that includes a comprehensive list of NDF volumes and daily spot rates for
64 FX pairs. We introduce WaveATTentionNet (WATTNet), a novel temporal
convolution (TCN) model for spatio-temporal modeling of highly multivariate
time series, and validate it across NDF markets with varying degrees of
dissimilarity between the training and test periods in terms of volatility and
general market regimes. The proposed method achieves a significant positive
return on investment (ROI) in all NDF markets under analysis, outperforming
recurrent and classical baselines by a wide margin. Finally, we propose two
orthogonal interpretability approaches to verify noise stability and detect the
driving factors of the learned tenor selection strategy.Comment: Submitted to the Thirty-Fourth AAAI Conference on Artificial

Agents in the market place an exploratory study on using intelligent agents to trade financial instruments
Tese de doutoramento em InformáticaThis dissertation documents our exploratory research aimed at investigating the utilization of
intelligent agents in the development of automated financial trading strategies. In order to
demonstrate this potential use for agent technology, we propose a hybrid cognitive architecture
meant for the creation of autonomous agents capable of trading different types of financial
instruments. This architecture was used to implement 10 currency trading agents and 25 stock
trading agents. Their overall performance, evaluated according to the cumulative return and the
maximum drawdown metrics, was found to be acceptable in a reasonably long simulation period. In
order to improve this performance, we defined negotiation protocols that allowed the integration of
the 35 trading agents in a multi-agent system, which proved to be better suited for withstanding
sudden market events, due to the diversification of the investments. This system obtained very
promising results, and remains open to many obvious improvements. Our findings lead us to
conclude that there is indeed a place for intelligent agents in the financial industry; in particular,
they hold the potential to be employed in the establishment of investment companies where
software agents make all the trading decisions, with human intervention being relegated to simple
administrative tasks.Esta dissertação documenta um estudo exploratório destinado a investigar a utilização de agentes
inteligentes no desenvolvimento de estratégias de investimento financeiro automatizadas. Para
demonstrar este uso potencial para tecnologia de agentes, foi proposta uma arquitectura cognitiva
híbrida destinada à criação de agentes autónomos capazes de negociar diferentes tipos de
instrumentos financeiros. Esta arquitectura foi utilizada para implementar 10 agentes que
negoceiam pares cambiais, e 25 agentes que negoceiam acções. A performance global destes
agentes, avaliada de acordo com as métricas de retorno acumulado e drawdown máximo, foi
considerada aceitável ao longo de um período de simulação relativamente longo. Para melhorar esta
performance, foram definidos protocolos de negociação que permitiram a integração dos 35 agentes
num sistema multi-agente, que demonstrou estar melhor preparado para enfrentar alterações
súbitas nos mercados, devido à diversificação dos investimentos. Este sistema obteve resultados
muito promissores, e pode ainda ser sujeito a diversos melhoramentos. Os nossos resultados
indiciam que os agentes inteligentes podem ocupar um lugar de relevo na indústria financeira; em
particular, aparentam ter potencial suficiente para serem aplicados na criação de fundos de
investimento onde todas as decisões de negociação são efectuadas por agentes de software, sendo a
intervenção humana relegada para tarefas administrativas básicas
