I do most of my investing during the evenings and weekends. So the Questrade "live" support chat has rarely been available for me "live". They'll reply reasonably fast by email though.
The great improvement at Questrade this month: a list of bond prices in a PDF file on their website (http://campaigns.questrade.com/Libraries/bonds/Questrade_Bonds_List.sflb.ashx
), or by email, and no more visible "trade commissions" on fixed income products. I looked at the PDF last night and was reasonably impressed with the inventory. Minimum purchase is $5k.
Previously, you had to call them to get bond inventory and prices, and I think they charged $25 per F.I. transaction. They just did not seem interested by the idea of selling individual bonds. I suppose the commission is hidden in the prices now, like at other brokers. Speaking of bond prices, now that the Questrade prices are online and available even to people how do not have Questrade accounts (unlike, say, at CIBC), I am looking forward to an evaluation of whether or not Questrade is competitive.
You still have to call them to buy and sell bonds, but at least you can evaluate your choices before calling now.
