Yesterday's cross-inspired strong rebound from 90.23 suggests the decline from this Monday's high at 92.33 has possibly ended there and upside bias remains for further gain towards 92.00, however, a breach of 92.33 is needed to confirm the upmove from 88.01 (this month's low) has finally resumed and extend gain towards 93.00.  
On the downside, below 90.80/85 would defer this bullish scenario and risk weakness to 90.50 but aforesaid support at 90.23 should hold on first testing.
