Marked on the charts is the starting price on the cross over for the last two times, along with a purple line on the when the past two crossovers occurred.
The past two times, ETH has risen by at least $10 in the immediate term & trended up past resistance quite easily.
This would still be a short term long position, would not be surprised if ETH shot up in the next four days until Constantinople then crashed to $80 again.
I would not consider a overall market for ETH unless the price reaches $220, then $320+ for higher highs.
I have been watching ETH and with Constantinople taken into account, I predicted the recent drop a week before it happened here:
This downward on the dark chart is the same as on the linked chart - ETH hasn't broken it, but has tried multiple times since August 2018.
On the 4hr the Histogram has flipped, the signal has gone below the MACD for a bullish divergence, RSI is showing oversold. (but those do not update on the chart above).
There has been a volume drop since I posted this, giving less conviction to the short term bullish signals than when I posted.
