Stock Research/Real-time Level 2

I use BMO MarketPro because it came free with my BMO InvestorLine accounts. Supposedly displays Level 2 because I can see the various bid/ask and lots at a basic level. It also lets me trade directly from the app instead of logging onto an individual account, although I haven't figured out how to do this with several accounts simultaneously.

There is also free software which is sorta real time, at this site: http://www.freestockcharts.com/

FreeStockCharts lets you display such charts as MACD, RSI, ADX, etc., as well as customize your holdings with fundamentals like price/book, foward/trailing P/E, etc. But that's nothing new - you can get those from Yahoo Finance or other sites too (although I find the information can't always be trusted at any free sites).
