RE:RE:RE:RE:Explanation requested...well this is not easy to explain. SPX and STLXF has the same CUSIP but different ticker for sure. For an American who wants to avoid the currency fee, it's better to buy (or sell) STLXF. But the seller may be on the TSX-V. In that case the transtion goes thru OTC ant then thru TSV.
I noticed that at the opposite. when we Canadian trade on the US side, if we sell, it's count on the daily short report. Might be because our broker goeas trhu another broker and this one does not have the certifcate yet so considered as short.
