A sale of stock occurrs between two parties. IF a transaction takes place on a Canadian exchange for example. Joe puts up 1000 shares at 2$ on the ask and Bill completes the order. They are both in Canada with stock trading accounts in Canada and trade the symbol EVIO on a Canadian exchange; that volume will not reflect on the US exchange.
Neither will the price. Sort of. IF the 2$ (US) sale price in Canada is close enough (say the recent OTCQB trade was at $1.98) then nothing.
If though... that 2$ trade in Canada happened and the US price bid/ask was around say $1.70 then you could anticipate a fast rise in the US price or a fast drop on the Canadian side because you know smart traders are going to arb the hell out of that price discovery failure.
Fast rise = IF that 2$ trade happened because of strong interest and high volume in Canada while the US was a little slower in volume... Then the US market would race to catch up.
The thesis re. evio is that an educated Canadian investor marketplace used to and loving cannabis stocks who have not to this point been able to purchase EVIO on the OTC due to restrictions on their TFSA accounts because of lack of canadian listing - will be able to play.
The volume on the OTCQB on any given day in the future could be a moribund 60k for the day with a price movement 5% one way or the other. While on that same day the volume in Canada could be 600k for the day driving prices up 10-20% ... the US market price discovery will quickly follow suit
