  • HPC for AI-based trading robots: A success story with Smart-Markets GmbH

    Technical/scientific Challenge

    In the ever-changing financial markets, adaptability and innovation are crucial for sustained success. Smart-Markets GmbH is an SME that develops and offers automated trading robots for medium to long-term stock trading and foreign exchange (forex) Day trading. Since market dynamics change over time, the performance of a trading algorithm diminishes when it is not able to adapt to market changes. Therefore, maintaining continuous effectiveness of the trading robots is one of the major challenges for Smart-Markets, currently requiring continuous back-testing and recalibration of the trading robot algorithms.

    Solution

    To address this challenge, Smart-Markets collaborated with SIDE in a Proof-of-Concept (PoC) study to explore using advanced Machine Learning techniques, specifically Reinforcement Learning, to improve the adaptability of their trading robots. As shown in Figure 1, the robot traded in the EUR/USD stock market. More than 10 years of high frequency tick data, which records every price change in trading, was used for the training and the subsequent test-trading of the agent.

    Figure 2 depicts the results for a simplified scenario, in which no trading fee was applied for the transactions. After an initial random action phase in the first years of trading, where the net worth of 100.000 USD did not significantly change, the agent started making its own trading decisions. Evidently, the predictions of the agent were sufficient to achieve a continuous profit over several years of trading, even in periods of overall negative trends.

    Benefits 

    • SIDE helped Smart-Markets leverage HPC resources for processing and analyzing large-scale, high-frequency financial data.
    • The PoC enabled the testing of AI-based trading robots, which could be adapted to changing market conditions within Smart-Markets trading strategies.
    • This PoC serves as a model for exploring broader adoption of advanced computing in the financial sector and beyond.

    Results

    With AI expertise provided by SIDE, this PoC allowed Smart-Markets to explore a new technology without first needing to acquire AI experience. The results show that an AI-based trading robot has the potential to trade profitably over multiple years by dynamically adapting to market changes in real-time. However, within the scope of this project, it was not possible to train a robot that makes a profit in realistic scenarios where a fee is required for each action. To adapt the trading robot to realistic scenarios in the future, the scope of this PoC could be significantly expanded by e.g. incorporating data from several trading prices into the training model.

  • webDO3SE: An Unprecedented Tool for Measuring the Global Impact of Tropospheric Ozone on Plant Life

    Technical/scientific Challenge

    Ozone, a protective compound in earth’s stratosphere, also occurs in the lowest layer of our atmosphere, the troposphere. Tropospheric ozone, though, is harmful to the climate, human health, and vegetation by reducing biomass, harvests, and biodiversity. Quantifying its global uptake by plants is crucial but challenging because it requires numerical modelling that correlates fine-resolution ozone measurements, plant specifics, and meteorological parameters, which are only available for individual sites and limited time periods, making quantification impractical and meaninglessly fragmented.

    Solution

    The TOAR data infrastructure solves the problem of fragmented data. It couples the TOAR database, which is hosted at JSC clouds and contains one of the world's largest collections of ground-based ozone measurements, with the meteocloud, a collection of meteorological data also at JSC, as inputs to the ozone deposition model DO3SE. The workflow of webDO3SE is shown in Figure 1. Via a web interface, users can easily access the data and perform impact estimates themselves in their browser. They select a site and a species by REST query to webDO3SE. Then, all the parameters and inputs needed to run the model are automatically gathered on-line. The model output is then provided to the user directly in the browser for further analysis.

    Flowchart illustrating a data processing workflow within a DO3SE web application. The process begins with a yellow box labeled "REST query, run specifications," leading to a green box labeled "Raw, hourly data," which is connected to "TOAR-DB" below. The flow continues to "Preprocessing," then to "Hourly input." Above "Hourly input" is a box labeled "Parameters," receiving inputs from "growing season," "parameterizations," and "basic station info." The flow proceeds to "Model run," associated with "FORTRAN model" below, and then to "Post processing." The final step is a yellow box labeled "Fast API output." The entire sequence is enclosed within a larger box labeled "DO3SE web application."

    Benefits

    • Tor data combined with HPC resources and the meteocloud facilitates access to an unprecedented scope of tropospheric ozone data.
    • WebDO3SE provides a unique interface for researching tropospheric ozone impact on vegetation.
    • Studying tropospheric ozone at a global level empowers environmental agencies.

Der Text ist zentriert und verwendet eine einfache, serifenlose Schriftart. "TOAR" ist in dunkler Farbe, während der restliche Text in einem helleren Blauton gehalten ist.

    The Tropospheric Ozone Assessment Report (TOAR) is an international activity under the International Global Atmospheric Chemistry project, which aims to assess the global distribution and trends of tropospheric ozone and to provide data that are useful for the analysis of ozone impacts on health, vegetation, and climate. The TOAR data centre provides access to the TOAR database, which compiles air quality monitoring data from thousands of sites around the world.

    Scientific impact

    As climate change progresses, the greenhouse gases and compounds that beget tropospheric ozone will also likely increase. Historically, studying the far-ranging impacts of tropospheric ozone on food security, carbon sequestration, timber production, and protection against soil erosion, avalanches, and flooding has been hindered by fragmented access to data. Nevertheless, HPC infrastructure combined with TOR data mitigates that fragmentation and enables the scaling of scientific studies to support public entities.

    The TOAR tool, webDO3SE, is currently being used for a global deposition model intercomparison study and will in the future provide an unprecedently global assessment of ozone deposition of vegetation – the extent to which plants absorb and mitigate tropospheric ozone. Once webDO3SE is well established, it can also be used by environmental agencies to estimate tropospheric ozone-related crop damage and other negative impacts on vegetation. Over time the impacts of tropospheric ozone as well as any mitigation policies can be measured, tracked, and more accurately modeled to maximize future environmental and societal benefit.
