I do not normally trade much of ETH however I am looking to get long for the "longer" term. One of the main reasons I am looking at getting long now is the indicator. More often than not you will see when the averages (EMAs) are about to cross above that centre line, it will do so slowly and then one day it will snap right above it. This is what I believe is going to happen over the next few days.
If you then move your attention to the you will see the centre line (in brown). A lot of the time you will see price touch that centre line and then bounce off of it. I think that this could be a possible scenario and have even extended the upper and lower band to show how I think it will act. You can already see that the upper is expanding more than the lower band.
Definitely one to keep an eye on, good luck on this as I am not the most experienced!
