Sharing strategies with others is in some ways like bringing in new players to a poker game ( a good thing). And since there are so many different strategies involved with the same stocks, I have really seen no difference in any of the strategies we employ. We have some "super traders" who "take it to the limit" with the better strategies, and increase their "risk reward ratio" at times, but for the most part, good solid strategies will work for a long time. We have to adapt to the outside influences (decimals, MOCs, etc.), and modify pairs at times....but the sheer volume of these stocks is enough to carry many traders. Don
