There can be 0 volume all day but by the end of the day, there will be enough volume based on algorithms and conversion rate to reflect the MTLO price.
So with MTLO currently down .395 (10%), DRKOF will drop according to the conversion rate and whatever algo is put in place. Could be set where a 500 DRKOF sell volume matches the CAD/US rate. But there will be some phony volume by the end of the day guaranteed.
