As can be seen from the attached weekly chart, the strong downtrend has been arrested by a double bottom at 87.10. This retracement will now take its course but gains above the 61.8% at 101.70 or the major trendline just above there are considered unlikely. Similarly, short term falls back below the neckline around 92.50 are also considered unsustainable and should be seen as buying opportunities. Range trading is the strategy here with a s/t bullish bias and a m/t bearish bias.
