In 4H chart, closing below the Resistance level of 173.30 gave the price an opportunity for a slightly bearish move again. As it is shown here, currently the price is trying to continue its bearish move by breaking the Support level of 172.75 and closing 4H below keeping its move inside the bullish channel. In that case, we may get another opportunity for more sell signals and it opens the way towards 172.30 as the first target. Then, the price should test the Support level to continue its bearish move. But as long as the price stabilizes above the Support level of 172.75, it cancels the first scenario.

Resistance and support levels: R3 (174.40), R2 (173.75), R1 (173.30), S1 (172.75), S2 (172.30), S3(169.90)
