Modes; Parts of the explanation could be that traders took some profit, but why would OTC end that low when Merkur were so green? Merkur ended above 1.45$! (1.48$ with the current USD/NOK, but I believe it was closer to 1.46$ yesterday)
Now, if people didn't sell OTC into the red, then Merkur would be likely to be green again (well, maybe we would have some profittaking today and then green tomorrow). So, why sell OTC into the red yesterday?
Seems as if someone WANTS the PPS to go down... Unfortunetaly, it seems to be very easy (especially with the market makers on OTC - would have been different, altough maybe still easy, if our only listing was Merkur or some other place without market makers).
