Not a doji, fibo, if you take account of the gap open.
Worth taking a look at the long term weekly chart which is still comfortably in up trend. With that in mind and with the penultimate swing low holding today's low some may be tempted to play long for a continued bounce if today's high goes on Monday anticipating either a false trend change (with today a potential swing low) or the first reaction in a new down trend which may extend to around 6570 - 6590 or so.
Otherwise, the assumption is that the trend has changed and we await that reaction (should it continue) to extend to three bars to form a potential swing high and short opportunity.
good trading
