Quote from Error 404:
There are "sure thing" strategies. It is no myth. This particular strategy has only one flaw that I can see, and that is that it has to be done at a low enough level to stay "below radar" as to not be recognized and thus rendered ineffective, and it can not be done on a small scale (as I said) because it takes advantage of a situation that may not continue to exist indefinitely.
Then what you describe is an "edge" rather than the notorious HG. In that case, scrape together from friends, family and trusted associates enough to hit the sweet spot (enough capital to take advantage but not enough to remove the edge) and milk it for as long as possible. It is only a matter of time before someone else finds it and does it for you.
Good luck.
