ECU's chart rising from the low mirrors that of others rising from the November bottom..
IMO the specialist is creating the tight daily trading range, while you can see shares changing hands in volume and maybe on the ask you have no way of knowing who the parties are or what they are doing (eg MM accumulating).
Fundamentally the company is in a strengthening position and the share price is rising albeit slowly, with sideways consolidations between each rise, IMO that's all you need to know.
