FTSE wave count and long setup

FTSE wave count seems cleaner than that of DJI and S&P500, now on wave (5) of an expanding ending diagonal {5}, poised to go up on a corrective advance.
If a medium term buy limit @ 6527, with tight SL set at invalidation of wave count - if it breaks lower channel line or the next lower channel line. It's so tight, R/R =11.70
