Gold resumed its losing streak Thursday, dragged under by weak oil prices and a cooling economy.

The benchmark December contract for bullion closed down $13.70 at $625.30 an ounce on the Comex division of the New York Mercantile Exchange, while oil was shedding $1.89 at $70 a barrel recently, also on the Nymex.

Shares of the exchange-traded funds that hold the yellow metal,

, were swooning in line with the futures, both down over 2%.

An unexpected 0.1% drop in the Conference Board's index of leading economic indicators vs. an anticipated 0.1% rise added further evidence of a slowing U.S. economy. Waning Mideast tensions also were easing investor anxiety over the possibility of war interrupting oil supplies.

"As confidence grows in the viability of the ceasefire

between Israel and Hezbollah it's not surprising that gold and oil have eased off," says Neil Meader, senior metals analyst at GFMS, a U.K.-based specialty consulting house. "Right back to the beginning of July gold has steadily been tracking oil rather than the currencies."

Technical indicators, however, do not appear to be providing much direction to the gold market, which seems to have been trading in a range lately.

"A triangle pattern is forming, and usually when you have a market that's in a triangle pattern, you're going to have a breakout one way or another," says Rich Ishida, president of MarketVane in Pasedena, Calif. Ishida notes that the December contract failed to break resistance at $666.50 earlier in August, which he says is a bearish signal.

Ishida expects the "cycle of higher lows and lower highs" to continue until resistance or support can be broken. The MarketVane sentiment index for gold futures is now 67% bullish compared to figures in the 70s last week.

Despite today's losses the pennant formation still remains in tact, although piercing support at $615 would be even more bearish, he says.

Meanwhile, the London Metal Exchange has instituted a maximum $300 a day penalty for sellers of nickel contracts that cannot find the physical metal to fulfill contractual obligations.

"Nickel stocks are at historically low levels and we now have a genuine material shortage," states Simon Heale, CEO of the LME, in a prepared brief.

The move by the LME helped ease the market, which saw prices for the benchmark three-month contract back off $450 a ton to $28,500, off of Wednesday's record highs.
