Learning to Trade with Q-RL and DQNs

Price changes in financial products are largely random, representing an efficient market, but are often supplemented by salient features that provide additional structure which can be exploited for trading profits. Experienced traders are skilled at identifying such features and deploying profitable exploits. We present some methods for learning such exploits using Q- function based reinforcement learning and DQNs that are trained on simulation models for markets which progress through levels of realism with data provided by generative models that mimic both the randomness and salient features of the actual markets.

Portfolio Management Using Deep Reinforcement Learning

Prediction using supervised learning algorithms for financial time series modelling is hard and converting predictions into actions requires additional naive layer of logic. In this talk I present a financial-model-free Reinforcement Learning framework to provide a deep machine learning solution to the portfolio management problem. A deep neural network is used for generating signals based on historical price data, these signals are fed to a portfolio memory layer that optimizes transaction costs, the deep reinforcement learning agent trains itself using an exhaustive reward function based on long term and short term market performance. This problem is implemented on the cryptocurrency markets and compared with other well known portfolio management frameworks like trend following, mean reversion and equal weighting scheme. I show that the model outperforms the other frameworks but performance is very much dependent on the overall market trend in the long only setup.

Predicting Foreign Exchange Market Turbulence using Thick Neural Networks.

Foreign exchange markets are notoriously unpredictable and often expose international businesses and governments to potentially devastating risks. A case for deploying Thick Neural Networks (TNN) as a method to flag periods of exchange turbulence is presented. Following a brief introduction of the phenomena being modelled (exchange rate volatility) and the method deployed a walkthrough will be given on several (neural network) architecture considerations which enhance overall network predictive performance. A novel way for presenting network topology will be shared along with a method for selecting the best parameters whilst evaluating architectures (Teknikeller, 2014). Thick Neural Networks developed are presented with their out-of- sample turbulence flagging abilities and results are benchmarked against orthodox methods.

Aspect extraction for opinion mining with a deep convolutional neural network

In this presentation, we present the first deep learning approach to aspect extraction in opinion mining. Aspect extraction is a subtask of sentiment analysis that consists in identifying opinion targets in opinionated text. A deep convolutional neural network has been used to tag each word in opinionated sentences as either aspect or non-aspect word. We also developed a set of linguistic patterns for the same purpose and combined them with the neural network. The resulting ensemble classifier, coupled with a word-embedding model for sentiment analysis, allowed our approach to obtain significantly better accuracy than state-of-the-art methods.

Price Returns Prediction Using Recurrent Neural Networks With Long Short Term Memory (LSTM) Units

Traditionally RNNs have been used for text classification and sentiment analysis; in this paper, we extend the idea to price returns prediction. The primary objective of the models will be to accurately predict 5-minute price returns based on multiple price based features. In our network, we use stacked LSTMs instead of MLP architecture. LSTM units are preferred as its architecture helps in solving the vanishing gradient problem and enables in modeling the long-term dependency which is persistent in financial price series data.

Despite the fact that the topic of predictive scoring models building is often considered in articles and it was written not one book about it, many things remain out of sight. An attempt to consider some of interesting questions will be made in the presentation. It will be practical ways which help to answer on such questions as: how to estimate the maximum Gini before the start of the model building; how we could add non-maturing loans in likelihood error function; one additional way how we could estimate overfitting and how we can understand need we separate Fraud Prevention Model or not.

The usage of machine learning techniques for the prediction of financial time series has been used investigated for a (very) long time. Both in the academic and fund management words, generative methods such as Switching Autoregressive Hidden Markov and changepoint models are generally found to be unsuccessful at predicting daily (and higher frequency) prices from a wide range of asset classes. However, committees of discriminative techniques (such as Support Vector Machines or Relevance Vector Machines and Neural Networks) are found to give some interesting results. It however remains that there is no such thing as a magic recipe and that using machine learning model for financial markets faces enormous challenge due to the very nature of financial markets, i.e. an ecology of learning agents continuously creating information and having different

Deep learning for stock market prediction

In this talk I share with you two of our recent research projects leveraging unstructured data for predicting stock market movements. In the first project, we use open information extraction techniques to extract event structure out of news titles, representing the results using deep learning, and building neural network models to match them with S&P 500 company returns. In the second project, we extend the efforts further, by using deep learning models to directly learn representations of news abstracts, from which we predict cumulative abnormal returns of S&P companies over 3 days. The results are promising, beating sentiment baselines significantly without using time series data.

Deep Reinforcement Learning for Optimal Order Placement in a Limit Order Book

Financial trading is essentially a search problem. The buy-side agent must find a counterpart sell-side agent willing to trade the financial asset at the set quantity and price. The virtual space where the agents execute their trading actions is called limit-order book. We present a deep reinforcement learning algorithm for optimizing the execution of limit-order actions to find an optimal order placement. The reinforcement learning agent utilizes historical limit-order data to learn to an optimal compromise between fast order completion but with higher costs and slow, riskier order completion but with lower costs. We also give a technological overview of the system and discuss the challenges and potential future work.
