I am not a stock technician but my friend STOCKCHARTER is. I think he is correct that a Golden Cross is a long term indicator. By definition
"Investopedia explains Golden Cross As long-term indicators carry more weight, the Golden Cross indicates a bull market on the horizon and is reinforced by high trading volumes. Additionally, the long-term moving average becomes the new support level in the rising market.
Technicians might see this cross as a sign that the market has turned in favor of the stock."
