 IQ FEED

For real time and EOD data i found IQ feed to be the most reliable,. Its service is also very reasonable compared to other real-time providers 

EOD DATA

End of day data provider is a very interesting feed for end of day data, you can choose 20 years of historical data on any single stock commodity or index or in groups for a single fee. It also offers daily updates making it a virtually seamless file with little work  

                                                                                                            Free Data

 Yahoo Finance

Yahoo Finance is perhaps the most well-known source of free daily stock market data.   
 

 Google Finance

Google Finance is often touted as an alternative to Yahoo Finance.  it also updates and integrates the OHLC data from the most recent trading day much more quickly than Yahoo  

 Quandl 

 Most of their free data is sourced from Yahoo and Google finance. Quandl also contains a wider variety of data but is somewhat complicated to format
