Gold futures settled Friday at their lowest level in six weeks, logging their third straight weekly loss as investors looked to the latest economic data to help gauge demand.

Gold for June delivery on Comex US:GCM5 fell $7.90, or 0.7%, to settle at $1,174.50 an ounce. After tallying a loss of losing a total of nearly $40 over the past two trading sessions, prices closed at their lowest level since March 19.

Tracking the most-active contracts, they finished 50 cents lower than last week’s settlement and have now fallen three straight weeks.

July silver US:SIN5 shed 1.8 cents, or 0.1%, to $16.135 an ounce, with prices gaining roughly 3.2% for the week.

Many European and Asian markets were closed Friday for a holiday.

Analysts said gold was seeing some follow-through selling pressure after it ended April with a whimper.

Tyler Richey, an analyst for the 7:00’s Report said the market is “seeing more of an unwind” of the pre-Federal Open Market Committee rally from early this week. Gold has been falling since the Fed made its policy announcement on Wednesday.

“Once futures pushed through support at $1,180, it caused another leg lower as technical traders threw in the towel on their long trades,” Richey said.

Prices dropped more than 2% on Thursday to leave gold with a 0.1% monthly loss, after a larger-than-expected drop in first-time claims for U.S. jobless benefits. Upbeat economic data can dull investment demand for gold.

Data released Friday showed that the Institute for Supply Management’s manufacturing index was flat at 51.5%. Consumer sentiment rose to a final April reading of 95.9—matching a preliminary estimate, while construction spending fell 0.6% in March.

The ISM factory employment number was at its weakest point since September 2009, said Naeem Aslam, chief market analyst at AvaTrade. The ISM manufacturing and construction spending data came well below the forecast and that provided some support for gold, he said, with prices moving off the session’s lows.

The main support for gold is at $1,168 and a break of this level will open the floor toward the $1,140 level, said Aslam, adding that price resistance is at $1,220.
