FinMem is built from three modules: profiling, which defines the agent’s professional character and risk personality; memory, a layered store with an adjustable cognitive span that ranks and retains market information over different time horizons; and decision-making, which converts retrieved memories into trade actions. The authors report that adjusting the agent’s cognitive span and personality settings changes trading performance.
The implementation supports OpenAI models, Hugging Face models served via Text Generation Inference, and Google Gemini, using text-embedding-ada-002 for retrieval. The repository’s worked example trades TSLA over June–October 2022; the system was also entered in the IJCAI 2024 FinLLM Challenge single-stock trading task.
