Silver falls again and marks weekly loss

Silver prices fell on Friday for the fifth session in a row amid selling pressures on the white metal on profit-taking, while the dollar rebounds today. 

Silver last traded at $17.93 an ounce, down from the opening of $17.97, with a session-high at $18.04, and a low at $17.79. 

Silver's drop today comes on profit-taking that started this week, with the white metal marking a weekly decline. 

On the other hand, the dollar rose today on the back of upbeat U.S. housing data, and after U.S. treasury secretary Mnuchin announced they're in the final stages of drawing up a tax reform plan.

Additionally, demand waned on safe haves while sentiment improved, with global stocks gaining ground overall this week.
