As for Ethereum
Our consistent style is to short weak and long strong
Ethereum has been making noise since last Sunday, the daily line shows a shrinking pullback, and it has crossed the bull-bear boundary. You can do swing trading, but don't have a bearish mindset.
Ethereum retraced to the target of 2550 yesterday, comparing the rebound with Bitcoin, who's strong and who's weak.
Intraday resistance is around 2690
Support is at 2550; if it doesn't drop below here, the 2640 resistance won't be strong enough.
If 2550 breaks, just wait around 2480; don't let any teacher start talking about an Ethereum pullback target of 2200 before the position is even reached.
