How to get bars for FTSE or DAX

Hi, I understand that one can’t trade on non-U.S. exchanges with Alpaca. What I’d like to do though is to use information gleaned from foreign stocks as a predictor of NYSE trends. Even indexes like FTSE or DAX would be enough to get started. Does anyone have an idea of how best to get them. It doesn’t appear to be possible with Alpaca. Thanks. . .
