The FTSE 100 found support at 6400 and the rising trendline. Recovery above 6600 would indicate another test of 6850. Rise of 13-week Twiggs Money Flow trough above 17% (the most recent high) would strengthen the signal. Failure of support at 6400 is unlikely, but would warn of a primary down-trend.
* Target calculation: 6700 + ( 6700 – 6400 ) = 7000
