Have you ever had any experience (at any moment at all?) of the fear for worrying your trading edge would become inefficient in the near future?
What would you do to prepare for it?
How to overcome it, technically (such as starting a hedge fund) and/or psychologically?
Or do you think a true edge would never lose its efficiency forever?
