Ark has retraced nicely back to the 0.618 Fib level, and looks like it has bounce off the support line nicely. If it does bounce from here we can use the longer green line as a base of ascending support. Current support line has been tested twice in the last day or two so if it can pass the blue line (entry point) then it looks a good buy. This will also confirm with me that it's bullish in the bigger picture. If price crosses back under surrent support line, then I can see it heading towards bottom support (~0.00175)
