GBP/USD's rebounds to as high as 1.6515 so far today but upside is still limited below 1.6573 resistance. Intraday bias remains neutral. Another fall is still in favor with 1.6573 resistance intact. Below 1.6269 will resume the whole decline from 1.6744 to 1.6166 support first. Break will target 1.5935 key near term support next. However, above 1.6573 will indicate that fall from 1.6744 is finished and will bring stronger rally to retest this resistance instead.
In the bigger picture, price actions from 1.3503 (2009 low) are treated as consolidation to long term down trend from 2007 high of 2.1161. Rise from 1.4230 is treated as the third leg of such consolidation and with 1.5935 support intact, such rise could still continue for 1.7043 resistance. But after all, strong resistance should be seen between 1.7043 and 50% retracement of 2.1161 to 1.3503 at 1.7332 to limit upside. On the downside, break of 1.4230 support will be the first signal of down trend resumption and will turn focus to 1.3503 low for confirmation.
