Possible ascending triangle with RSI bullish divergence

Santander's price has been on clear decrease from May's 2017 all time high, but it's showing some stabilisation or loss of interest in a symmetrical triangle, ever so slightly ascending. The Stochastic RSI is showing what could be a bullish divergence. If the price breaks the 5.90 resistance it would signal a change of trend. Otherwise, the 5.80 price area could be a good place to take benefits.
