How To Buy ALLRF.PK & AAA.V
Issues with AALRF.PK
This can be expensive if your broker hits you with a DTC Rejection Fee (or a foreign stock fee). For example, TradeKing's DTC is $75 in addition to their regular commission. That's tough to justify with a penny stock.
Worse, some brokers, like Zecco, don't do five symbol ending F transactions.
Issues with AAA.V
This too can be expensive as some brokers charge around $24 as their commission to trade on the Venture exchange.
Fidelity
I've found that Fidelity is the most cost effective. First, they will allow non-retirement accounts to be set up (you have to request this) for foreign exchange trading (and you can settle in local or US currency). The commission is their regular $7.95
Retirement accounts, however, are restricted to US trading only, so you'll have to use ALLRF.PK. Still, the $7.95 commission is all that you will be hit with. Just remember to use AAA.V for your real-time quote and that this is in CAD$ while your bid for ALLRF will be in US$. You can call Fidelity and they can give you real-time conversions so you can place your order. And please, use a limit order.
