Gold At the 50 Day Moving Average

Gold was all over the place today. At the open gold was flat, then it was up $9.00, then it was unchanged, then it was down $9.00. I bought GLD right before the close today because it is near the 50 day moving average..I was waiting for a dip to the average and that's exactly what we got today. Tomorrow if GLD closes below the 50 day moving average, I will exit the trade at a small loss, but if it rallies I will hold for a large move up. I'm not thrilled with the way it closed but I figure the risk reward is good here so I bought some.
