Trendline break long setup

We can see from the higher timeframe that price has been bouncing on support and is now ready for a new leg upwards.
Price formed a double bottom with the second bottom being lower, and the RSI being higher, so this gives us RSI divergence.
Furthermore, the second bottom has formed a Head & Shoulders on the lower timeframe, thus creating a spring + breaking the downwards trendline (in blue).
