Why Trend Following is not as Easy as it Seems | feat. Richard Brennan | Systematic Investor 231

Richard Brennan joins us to reflect on the learnings so far from the new CTA series. We also discuss how to set your stop loss when entering a new position and why you should not allow your trend models to go "backwards", how to fit your model to price data and why it is important to understand the signal to noise ratio in your trading to avoid overfitting. Additionally, we discuss how random entries can work for your models, but why they are not truely random and the challenge of separating luck from real signal, why it is preferable to have an under-fit model as opposed to an over-fit model when developing a trend following system and how to reduce your chances of having an overfit solution. We round off our conversation discussing why trend following is not as easy as it might seem and much more.
