Ark has seen a nice upward run. As often the acceleration of the upmove (taken Ark out of the upward channel on the upside) also signaled the temporary end of it. Ark fell back in to the channel, all the way to the bottem of it, where yesterday it found support (green oval).
The RSI-indicator never came close to oversold condition (not even on the 1 hour candles), meaning there is enough faith in the market Ark can overcome the drop.
Now price has to break the current resistance line (red) to take Ark back to the top of the upward channel. I wouldn't bet on new ATH's (0.0012+) soon but somewhere around 0.001 seems very possible.
