All of the free futures web sites have various deficiencies/discrepancies/inconsistencies. I can't recommend any free ones. The data quality is simply terrible.
If you're serious about trading futures you should consider a relatively-inexpensive futures data feed. These can be found for less than US$30/month plus usually a once-off historical data fee.
Some issues include:
No data even though settlement has occurred on a particular day
Ignoring data from holiday periods (holidays vary from contract to contract, and are not done on an exchange-wide basis)
Showing trading data on non-trading days
Assigning volume to the wrong day, where volume is provided with a one day delay from the exchange
Not incorporating official volume from all trading sessions
Not specifying which session(s) are included in the data
No sanity check for illogical data (eg. open < low)
I should disclose that I'm a part owner of a data vendor, but that puts me in a good position to be able to assess the terrible data that is out there. We spend about 2 man hours every trading day resolving discrepancies in our futures data feeds. Over the years this adds up to a huge amount of effort, but we have to charge a reasonable fee to access such quality.
Cheers,
Richard.
