Sorry for the late answer!
You can use it, but I would manually look that you are well diversified if you want to be globally invested. QuantTrader does not know about this and it can well be that you end up invested near 100% for example in the US market.
You can add such a bond (for example CMF or PCQ) without problems to any strategy using QuantTrader. Mainly PCQ looks like a good ETF.
