Foundation Models in Trading: Time Series Forecasting with Google's TimesFM 2.5 in MetaTrader 5

Foundation Models in Trading: Time Series Forecasting with Google's TimesFM 2.5 in MetaTrader 5

Time series forecasting in trading has evolved from traditional statistical models (like ARIMA) to deep learning approaches, but both require heavy tuning and training. Inspired by advances in NLP, Google’s TimesFM introduces a pretrained “foundation model” for time series that can perform strong forecasts even without task-specific training. For traders, this is powerful because it can be efficiently fine-tuned on their own data using lightweight methods like LoRA, reducing overfitting while adapting to changing market conditions.
