Enum DateRange 

pub enum DateRange {
    Day1,
    Day5,
    Month1,
    Month3,
    Month6,
    YTD,
    Year1,
    Year5,
    All,
}

Preset date range for quick navigation.

Each variant describes a lookback window from the current time. The default preset is Month1.

Use start_timestamp to convert a preset into an absolute DateTime, or estimated_bars to estimate how many bars to fetch for a given timeframe.
