This worked out beautifully today and I went long at 63.25p. It's finished today with a perfect hammer right off that main trendline and horizontal support of 63p.
Note how the long term RSI support came into play at exactly the same time lending weight to the move. In addition, after the initial bounce, price dropped back but were again bought confirming that the bears had lost this particular battle.
What I'll look for now is for the RSI downtrend to be tested. A break through that and price ought to follow through its own trendline.
For now, though, like any candle pattern, this needs confirming tomorrow. Resistances are at 73.25p, 76p and the 79-81p area
