Quote from logic_man:
So, you think the lifespan of an objective edge is more than 10 years?
The way Surf talks, they only last a couple of years and then they (apparently) disappear forever.
With such a major discrepancy in opinion, it seems to me that you are better off trading one as soon as it appears, so long as you keep your position-sizing such that you are not over-betting on any individual trade.
Since we're just throwing opinions out there, I personally think the market evolves at about the same pace as humans, since it is a completely human construct. As a result, the idea that in a single lifespan the market will "evolve" strikes me as a rationalization for failure.
.
Now, if there were such an edge, what would likely be at its core?
Volatility.
So, if you can build an edge where volatility is the central focus and decision driver, you can build an edge that endures across all market regimes and, really, all markets period.
