Not an "edge" in the traditional sense. That would (to me) imply a statistical advantage of one thing being more probable than another. This is not that sophisticated at all. Just finding a "loophole" so to speak in the mechanics of a certain kind of trade.
By edge I didn't mean in the statistical probabilty sense necessarily...certainly a rule loophole is a legitimate edge until others figure it out. Take the overnight/overseas mutual fund loophole that Gary Smith talked about in his book "Trading For a Living". Basically that strategy took advantage of a rule (or lack of rules) that allowed for risk free arbitrage on overnight trading. This would certainly be considered an edge in my book. As more people found out about it (and funds felt the pain of money flowing out the door) the edge was quickly removed in the form of new redemption rules. I know that a lot of prop trading is/was based on taking advantage of exchange rules that are not easily exploited by the retail investor. Edges come in all shapes and sizes.
If its a rule based edge as your posts seem to suggest, then hit now while the hittin' is good!
