Is it possible to trade a stock that's not in QC (e.g., OTC or international stock) by importing the daily prices with a CSV and creating a custom stock to trade?

For example, in this attached backtest, I'm attempting to import price/volume data for CLXPF since it's not in QC. 

I'm stuck at the moment, and not even sure if this is possible. I've reviewed the documentation on importing custom data, but haven't found the answer to this.
