Currently, for $ETH Ethereum, I suggest entering a short position at 2730. There have been two previous upward attempts at this position, but neither broke through, indicating that the resistance at this level is strong. It is very likely that a third attempt will be made, so I recommend establishing a short position here, with a loss limit set at about 10-20 USD. If this resistance level is broken, then look towards the 3030 position, which is also a very strong resistance level.
