The fast rising from below 19, the short-term resistance at 19.80 and 20, if able to recover further possible to test 20.20/50, and the need to break through this region can be sent upstream signal. Below the support in the 19 line, hold the short-term downward limited space. We expect the short-term or continued in the 19 to 20.00/20 after the fall, or try to go up.
