Considering the key fibonacci retracement plus volatility indicators, there's a huge volume pressure on VALE right now, it's been looking for a bottom for some months and its also showing some signals of trend reversal, I'd consider a long position for the next few weeks to see where it goes (Hopefully, a little bit up)
We will probably see the result in the next few days already.
