body: <p>I need help for getting a pandas <code>DataFrame</code> from a <code>dict</code> like this one (2 levels):</p>
  
  <pre><code>{u'instrument': u'EUR_USD',
   u'candles': [{u'complete': True,
                 u'closeMid': 1.26549,
                 u'highMid': 1.27026,
                 u'lowMid': 1.25006,
                 u'volume': 138603,
                 u'openMid': 1.26864,
                 u'time': u'2014-09-29T21:00:00.000000Z'},
                ...
                {u'complete': True,
                 u'closeMid': 1.244995,
                 u'highMid': 1.25774,
                 u'lowMid': 1.239455,
                 u'volume': 167259,
                 u'openMid': 1.242075,
                 u'time': u'2014-11-10T22:00:00.000000Z'}
                ]
  }
  </code></pre>
  
  <p>Columns labels and values should be <code>instruments</code>, <code>Complete</code>, <code>CloseMid</code>, <code>HighMid</code>, <code>lowMid</code>,<code>Volume</code>, <code>OpenMid</code>, <code>time</code>.</p>
