const (
	None       CandleAttributes = 0x0       // Default - not a candle
	ISCANDLE                    = 1 << iota // Is a candle - continuum data representation (not a tick)
	OHLC                                    // Has "Open, High, Low, Close" data in the candle
	OHLCV                                   // Has "Open, High, Low, Close" and "Volume" data in the candle

	HASFLOAT64                              // 64-bit version available
)

- if None, then there are no candle attributes - not a candle - if both HASFLOAT32 and HASFLOAT64 are set, the 64-bit versions of OHLC are named using a "64" after the column name - if only one of HASFLOAT32 and HASFLOAT64 are set, the OHLC have names: "open", "high", etc
