Question
When it is about to optimize the functional parameters of an algorithm that uses only a time price series as input data, the question is how relevant is the Cross-Validation Optimisation Method?
The additional question is what other optimization methods can be applied with good and proved results for this case and what papers can be considered in order to build a sustained literature review on this subject?
Question
The goal of TheRiskPsychology project is to identify emotions, fears and social trust related with the financial trading activity using algorithmic trading and automated trading systems.
