Still didn't get why ? Some reasons below

1. EMA10 cross up EMA20, that's a signal for those who trade based on EMA.
2. Two Lines Break reversal yesterday, someone start to enter long now !
3. Higher Low with lower/higher/flat low still unknown, 48.31 will be critical.
4. Think about the DXY, USOIL and OPEC.
5. Short after a shorting signal appears at least. No sign yet.
