The between $1.6 and $2.0 looks solid and could result either in strong retracement upwards or a trend reversal. There are 3 resistance levels to watch:
61.8% Fibs ($5.3)
50.0% Fibs ($6.8)
38.2% Fibs ($8.3)
Break and close above the final resistance should confirm the long-term uptrend, although it if any of them will be rejected, consolidation period could take place. On a downside, only break and close below the $1 psychological support could invalidate outlook.
