I don't know. But I have some doubt that it can be taught. It has been discussed long time ago on this subject between William Eckhardt and Richard Dennis. And many had agreed that Richard Dennis was right supporting an argument that successful trading can be taught over an argument that it has something to do with trader born talent. However, I have some doubt, if it can be taught it mean anybody with an average intelligence can be successful after getting a good training. The following reasons: 1. To form a Turtles group, why need the interviews to select candidates since any one can be taught then just pick by random. 2. Why not all the Turtles are successful since they got the same training and used the same winning system. Would like to here your opinion?
