UK100 nearing potential reversal @ around 6780 or just below

Looking at Daily chart of FTSE the 6780-6860 area is previous resistance area and it coincides with 78.6% Fib retracement drawn from Apr'15 high @ 7127 to Feb'16 low @ 5494. My preference is shorting from 6760 with stop above 6860 and initial target @ 6450 and longer term 5750.
