i use a limit order based on CN price; look up AET-UN.TO, multiply by CN$ exchange rate; so AET closed at about 8.70; X.956 or so, you get 8.29. then because I am cheap, when I am ready to buy, I would place a limit order to buy at 8.28 or 8.27 depending on the direction of the market at the time. or just a good till cancelled order at the price you want, say 8.25 US. it is tricky with the exchange rate and CN transactions but this has worked well for me in the past;
I use Fidelity which I am finding out does some of these CN trusts/oils do not clear thru DTC so they charge a $50 fee. others on the board are using other firms which apparently don't sock you with this; they are saying Merrill Edge etc. But I don't trade much so it is not worth switching all my accounts from Fidelty (stock/ira/roth) to another broker at this time. hope this helps.
I am in this for the long term, with oil down again and Argent down with it, still on my radar for adding. Eagle trust also looks good, it has had a run from its lows, more TX oriented.. GLTYou
