The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.NEW YORK ( fxtechstrategy.com) -- Although the euro-dollar currency pair (EUR-USD) closed only marginally higher the past week, it continues to hold its recovery tone that was set at 1.3144. This leaves scope for further strength toward 1.3937, the pair's Sept. 15 low. Further out, resistance stands at 1.4283, the pair's Sept. 6 high, and at 1.4498. EUR-USD's weekly relative strength index (RSI) is bullish and pointing higher, suggesting further strength. Alternatively, the risk to our upside view will be a return to the euro-dollar's Sept. 28 high at 1.3690 and its Oct. 18 low at 1.3650. We may see a reversal of roles as support at the latter level turn the euro-dollar currency pair higher, but if that level is taken out, risk will build toward 1.3377, the Oct. 10 low, and then 1.3144. All in all, EUR-USD continues to build on its recovery strength started from the 1.3144 level.
