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?
if your edge is based on something specific then YES your edge can be gone, randomized etc there is nothing you can do, perhaps you could preempt your edge by 1 min or so, but tough luck if you edge is based on something constant then it will last forever you must understand you edge first and foremost
Do you mean diversification with several edges? How do you know in advance all the edges could never be high correlated one day, hence becoming inefficient at the same time?
Edges come and go all the time ,, but on the bright side it would get boring otherwise... its just a matter of time before someone catches on ...usually the broker .. imho Kap
Good thinking indeed! Would that be possible your broker simply adds much more quantity on top of your orders?
