In the Stone Soup story, everyone brought whatever they had to throw in the kettle. It didn't have to be anything fancy. Mostly what people brought to the kettle was so humble that the people bringing it would come with their eyes lowered, apologizing that they couldn't bring anything more worthwhile. Things that most people would discard: celery leaves, potato peelings, dandelions. It all went in the kettle.
What made it work was that no individual item brought had to be magnificent. The accumulated volume and diversity of what was put into the soup was what made it work. Everything, however humble or even seemingly worthless, turned out to have its value when contributed to the larger collection.
If the same tactic can be applied to stock trading, we shouldn't need to ask people to reveal their "Edge", or to bring their best strategy. Give us the stuff you can't get any use out of. Somehow, if it all goes in the pot, we may be able to stir up the whole mix and arrive at something worthwhile.
In this way, I humbly offered my "Peers Trading" method as a start. I make no claims that it's an Edge, that it's really a great method, that it will work even most of the time. Because it's no holy grail by itself, there's no need for me to be secretive or proprietary about it. It's just there, for what it's worth. But when combined with a bunch of other ideas from other people, other ideas that I myself would never be able to come up with, it may have its contribution to make.
If this approach might actually work for trading as well as for soup, it would eliminate the obstacle of proprietary secrecy that everyone feels about their possible or hoped-for Edge in trading. If somehow we can extract some worth out of almost any tidbit of an idea, we might find that there is in fact no holy grail, but that the nearest thing to it is a giant kettle.
