Candlestick trade data is easy to get. I downloaded mine from my broker (Interactive Brokers) - they provide 1 second resolution if required. If you want individual trades rather than candles, then you'll need to purchase from a data provider.

Level 1 NBBO I was unable to find any 'free' sources, so I purchased mine from tickdata.
