You have three things you can do. Sit out, buy, or sell. The overwhelming majority of the time, you should be sitting out. You should be buying, when all the clowns are telling you to sell. You should be selling when all the clowns are telling you to buy. Even when the clowns are chirping one way or another, you still should be sitting out in most cases. Put in more layman's term's "Don't overtrade" but act when your opponent has hopelessly over extended themselves. Thats the Wildchild Method.
The point is simply put by Shakespeare.
"There is a tide in the affairs of men,
Which, taken at the flood, leads on to fortune;
Omitted, all the voyage of their life
Is bound in shallows and in miseries."
