Waitedg, it's possible Ameritrade already has an "inventory" of UNITED BOLERO DEVELOPMENT CORP stocks that they bought on the Canadian market and used those to fill your UBDVF order even though the MM's aren't trading them yet.
Sometimes when I use my Fidelity account for a buy (or sell), on the execution order they state they acted as "market maker", which means they had shares in stock or took my sold shares into their inventory. If that's what they did, it's looks good for future potential. Maybe you could call and ask if that's what they did.....
Cash is King until further notice!!!
My comments on companies are usually my opinion of long term success (years). The PPS may go up or down greatly in the meantime depending on the number of greedy suckers with money.
