Not every part of the GARCH-FX journey has been a smooth sail. A notable experiment involved using a 3-state Markov chain for regime switching, which didn’t quite hit the mark. But the model’s modular nature allows room for better signals, promising future improvements. Another hurdle, the calibration of the vol-of-vol parameter, theta, remains heuristic at this stage. Cracking a reliable method for this would significantly enhance the model’s robustness.
#### The Road Ahead
For anyone invested in the development of quantitative tools for finance, GARCH-FX offers a glimpse of what’s possible when you challenge the status quo. It’s the product of taking risks and innovating with intent, exemplifying how even complex problems can be approached with fresh eyes.
