Short setting up on on Wolseley

It looks to me like a potential short is setting up here on Wolseley. It currently looks like there's still possibly upside to around the £50.00 mark, but that otherwise the set up is mainly short.

With indices looking near tops, I suspect that theres a good chance that the £50.00 level won't be hit - a fall below the lower diagonal could suggest a good short should be underway, or one could get in pre-breakdown, shorting any strength.
