backtest not going back far enough

[alias-noa]

I'm trying to run the strategy_multiple_datas sample and I have Alpaca Pro and using the default date for the backtest which is 1/1/2015, but it's only going back a few months from present date. I changed 'iex' to 'sip' for the data_feed parameter, and it changes nothing. Does the same exact thing. I'm using 1-day candles so I feel like it should really go back further. Does it work right for anyone else?

How did you manage to run it? Aren't you running into matplotlib and pandas errors on runtime?
