Ask HN: Best real time stock charts

For day traders here, what are the best real time charts/data sources you use? I'm looking for minute level candlestick charts as well as latest trades and bid/asks. Free or paid is fine as well. I'm also willing to look at trading anything - stocks, futures, currencies. Don't really care about technical analysis features except the most basic ones, but would be nice to easily compare different markets.

Thanks!
