Gold closed higher on Tuesday and is poised to extend the rally off July's low. Stochastics and the RSI are overbought and are turning bearish hinting that a short-term top might be in or is near. Closes below the 20-day moving average crossing would temper the friendly outlook. If it extends the rally off July's low, the 75% retracement level of the June-July decline crossing is the next upside target.
