Want free real-time streaming quotes and charts for stocks, Forex, and futures? There are few websites that do that but so far I prefer the one from investing.com. The only problem with it, it has lots of ads and it is hard to get to the chart you want. I found that you can go directly to their chart production server http://tvc4.forexpros.com and no ads, no pop-ups just free real-time streaming charts. Of course you get what you pay for (which is nothing) but it is good enough to look quickly at something.
S&P 500 futures
Type CME:US500 to get data for S&P 500 futures which is ES symbol on CME.
Crude Oil futures
Type CL for crude oil futures which has the same CL symbol on CME.
Dow Jones futures
Type US30 for Dow Jones futures which has YM symbol on CBOT.
ES futures are pointing to weak start of 2016 for US equity markets. Futures are down around 1%. Say thank you to China which just reported drop in December PMI to 48.2. Good luck to all traders in 2016!
Update: It is not just weak start of the year. So far it is the second worst start of the year in more than 80 years.
Dow's worst starts to a year over the past century:
-8.1% in 1932
-2.3% in 1922
-1.8% in 1983
-1.7% in 1930, 1980 and 2008
ETFs such as USO are not holding actual oil unlike gold ETF GLD which actually holds gold bars. USO uses futures contracts to track oil prices and they are pointing up or using fancy terms in contango now. USO fund each month has to sell front contract and buy more expensive next month contract. Because of that effect when last year oil prices dropped from $53.49 to $37.13 or drop of 30% the USO ETF went down from $20.36 to $11.00 or drop of 46% which is 16% difference thanks to contango and expenses. Looking forward into 2016/17 (here for example) 20% increase from $37 to $44.21 is already priced in into future contracts so if oil raises less than 20% USO investors will lose money. Oil needs to rally at least 25% to $46 for investment in USO to break even if you include expenses.
