Ethereum has broken up the resistance at $340. From here I believe we will see it retest $400 for a third time in its history. Note that the RSI is approaching oversold though on the 1D and has breached oversold on the 4hr charts; good buy orders may still be available if we get a small pull back down to $340. We see a gigantic ascending triangle forming on the 1D, and if it breaks up from $400 I think we will see ETH have explosive growth. That being said we must consider good levels of support for potential stop orders. Just below $340 is an obvious one, but I think the stronger support is the uptrend line (black line) making up the base of the ascending triangle.
