Agent system uses past trading memory to improve financial decisions

Agent Memory with Episodic Retrieval for Financial Decision-Making

Abstract: Large language models (LLMs) have demonstrated strong capabilities in financial analysis and reasoning, inspiring recent advances in agent-based trading frameworks. While these systems show promise, prior approaches either emphasize long-horizon forecasting or operate as stateless analyzers, limiting their applicability to the demands of trading in complicated settings. To address these gaps, we introduce META (Memory Enhanced Trading Agent), the first RAG-like episodic-memory-augmented multi-agent framework for financial decision making. META integrates a family of specialized indicator agents (e.g., Trend, MACD, Stochastic, RSI, SMA, AVWAP, Heikin-Ashi) with a Decision Agent that fuses their reports, and a Memory module that retrieves and updates past trading episodes encoded as market state embeddings with outcomes and reflections. By recalling relevant experiences and adaptively reweighting signals under similar market regimes, META achieves improved directional accuracy and robustness under short-horizon evaluation. Our results demonstrate that episodic memory provides a powerful mechanism for regime-aware, interpretable, and low-latency decision-making in trading and decision making. The code of this project is released on GitHub.

The gist
Financial trading is complicated and requires quick decisions based on lots of information. The authors created META, a system that remembers past trading experiences and uses that memory to make better decisions today. META combines several specialized expert agents with a decision maker and a memory module that recalls similar past market situations. This helps the system adapt to changing market conditions and make more accurate short-term predictions.

Transformer model improves long multivariate time series forecasting accuracy

SETTer: Sparse-Encoder Transformer for Long-term Multivariate Time Series Forecasting

Abstract: Long-term multivariate time series plays a significant role in many application areas such as power systems, trading, etc. However, their accurate prediction is quite difficult for conventional forecasting methods as they often exhibit high dimensionality and complex relationships. Recent works show that transformer-based approaches are quite effective for long-term forecasting thanks to their attention mechanism. However, in the presence of complex high-dimensional inputs, they show evidence of oversmoothing, limited capacity, and opacity. To this end, this paper introduces SETTer, a transformer-based model that addresses these challenges by incorporating novel techniques for decoupled self-attention and hybrid masking. The proposed techniques enable SETTer to effectively capture the dominant short- and long-term patterns across the temporal and channel dimensions. In addition, we enrich the model layers with simple explainable structures that indicate the discriminative pattern of SETTer. We show that with a single-layer transformer architecture, SETTer can effectively model long-term dependencies in the presence of varying data complexities. Extensive experiments on real-word benchmark datasets for long-term multivariate time series forecasting demonstrate that SETTer outperforms state-of-the-art models in 88% of the scenarios.

The gist
Forecasting many related measurements over long times is hard because the data is complex and high-dimensional. The authors developed a transformer model called SETTer that uses special attention and masking techniques to better find important patterns in both time and different data channels. SETTer also includes simple explainable parts that show what patterns it focuses on. Their tests on multiple real datasets show it beats many current top methods most of the time.
