$ERA — Sudden acceleration

Over the previous 15 minutes, the coin had lost just -0.13%, then its price fell by -1.3% on volume of x29.46. This is not a smooth continuation of the move, but a sharp spike in activity. Such surges often signal a rapid repositioning by participants who had time to adapt to the slow drift. What matters to an observer is that the momentum is concentrated in time rather than distributed evenly.
