Some more hassles: They've changed the data structure of RateData as shown below rather than introducing a second structure which includes the elongated information.
From O/L/H/C to O/H/L/C
They all of a sudded different on TickVolume and TradeVolume and introduced Spread - whatever Spread means to a candle based data representation (Average Spread? Median Spread? Last Spread? First Spread? Some randomly selected Spread?)
