NEW YORK ( TheStreet) -- Silver could continue its bullish momentum this week on technical indicators and a weaker dollar.U.S. economic data releases this week could indicate improving new-home sales, declining consumer confidence and rising durable goods orders. The eurozone is scheduled to release unemployment numbers, confidence measures, and retail sales data. These data releases could be mixed to positive for the dollar, while the eurozone macroeconomic factors are showing an upturn. Markets may be weighed down by the dollar, which has been deteriorating during the past seven weeks. Overall, a weaker dollar may push silver prices higher. Silver could maintain a bullish momentum this week on technical indicators as well. Last week, silver gained 1.76% on the COMEX to close at $18.10 an ounce and scaled as high as $18.28, breaching the resistance level of $18.05. This week, the metal is likely to test resistance at $18.38. Since silver is trading above exponential moving averages, the white metal could find support at $18 levels. The momentum indicator RSI (14) is treading at 0.517, indicating a marginal upside. Silver outperformed gold last week gaining nearly 1.8%. COMEX silver traded in the range of $17.44 to $18.28 an ounce. Silver futures for September delivery settled higher at $18.10 an ounce during the week.

The gold-silver ratio dropped to 65.62 from 66.80, as silver gained and gold declined. Gold was down 0.03% last week, in comparison to silver's 1.76% gain.
