The 50/200 golden cross confirms a trend months after it started; this is the same event on a swing trader's clock. Nine days overtaking twenty-one marks the short-term tide turning, and it turns often — which is why the 200-day filter is not optional. Above the long-term average the cross is a pullback ending; below it, it is usually noise inside a decline.
