Which is why, for Indices, if trading the Indices directionally as an outright? I like a repeatable process, that is either "Long" or "Long-Flat". To see what I mean? Look at the Long-Flat process of the Non-Correlated model. It has a repeatable reason to get out, a repeatable reason to get back in. And you can run history on it, back to like ... 1961, to see how it would have worked out for you. When you do that? It gives you confidence in doing it into the unknown future.
