Possible to run backtest on stocks no currently available on Quantopian?

I have a CSV with OHLC values of 100UK stocks, now my strategy looks for correlations between the US market and the 100UK stocks. Is there a way I can run the backtest using the OHLC from the UK stocks using Quantopian? That is I still want to use lots of the US data avaliable on Quantopian when developing the strategy but I want the universe to be my 100 UK stocks.

Welcome to Quantopian.

Here on Quantopian, you can only simulate/trade US equities and futures.

Quantopian is built on the open-source Zipline backtester. On your own rig, you can modify Zipline to trade those UK stocks. As you note, though, you won't have access to the other Quantopian data sources. Local zipline implementations are entirely bring-your-own-data.

I've seen algorithms buy ADRs before so I did a test using the filter. Filtering for United Kingdom as the headquarter country didn't return any stocks, but filtering for London as the headquarter city returned around 20 stocks. They were mostly large companies, like Unilever, that trade on the NYSE as well as the LSE. This method doesn't provide data for trades in the British market, though.
