Ethereum showed strength by trying to push higher but without success. The candlesticks are showing long wicks because they got rejected by the uptrend line, resistance level (former support) and MA50 level. This is a good indication that the price is trying to push lower. If it's going to break below of 640 level, it's more likely going to continue to next support zone which can be found close to MA100 and it can be traded at these level with confirmed reversal signal. Without confirmations, it's better to wait for better trading opportunities!
