Gold has recovered this week and defined a key near-term support at $1764.8, Nov 30 low. Tuesday's price action is a bullish engulfing Japanese candle line and highlights a possible reversal. If correct, this signals scope for a climb towards $1844.5, the 20-day EMA and the former key support at $1848.80, the Sep 28 low. On the downside, a move below $1764.8 would confirm a resumption of the downtrend.
