Do you still re-optimize when the performance holds?

Summary

• The post discusses the optimal strategy for re-optimizing algorithmic trading systems, specifically whether to stick to a fixed schedule or only re-optimize when performance degrades.
• The author's thesis is that if a trading system continues to perform well, it might be better to avoid re-optimizing it ("if it ain't broke, don't fix it") to prevent unnecessary changes or overfitting.
• This is a high-level discussion on trading methodology and does not contain specific market analysis, data, or due diligence on any particular asset. It is noise from an investment thesis perspective.
