USStockTradeBitmaps 保存美股各年的交易日真值位图。

Types

type YearTradeBitmap

type YearTradeBitmap struct {
	Year int
	Bits [6]uint64
}

YearTradeBitmap 表示某一年的交易日真值位图。 6 个 uint64 共 384 bit，足够覆盖一年 366 天。 Bits 中 bit 0 表示当年 1 月 1 日，bit 1 表示 1 月 2 日，以此类推。 bit=1 表示交易日，bit=0 表示非交易日。

type YearTradeBitmaps

type YearTradeBitmaps map[int]YearTradeBitmap

YearTradeBitmaps 表示按年份索引的交易日真值位图集合。

func (YearTradeBitmaps) IsTradeDay

func (bitmaps YearTradeBitmaps) IsTradeDay(day *base.CalendarDate) (bool, error)

IsTradeDay 判断给定日期是否为交易日。

func (YearTradeBitmaps) ListTradeDays

func (bitmaps YearTradeBitmaps) ListTradeDays(start, end *base.CalendarDate) ([]base.Date, error)

ListTradeDays 返回闭区间 [start, end] 内的交易日列表。

func (YearTradeBitmaps) OffsetTradeDay

func (bitmaps YearTradeBitmaps) OffsetTradeDay(day *base.CalendarDate, offset int) (base.Date, error)

OffsetTradeDay 返回交易日偏移结果。 offset > 0 时，返回 day 之后的第 offset 个交易日，不包含 day 当天。 offset < 0 时，返回 day 之前的第 -offset 个交易日，不包含 day 当天。 offset == 0 时，仅当 day 当天是交易日时返回 day，否则返回 error。

func (YearTradeBitmaps) SupportedYearRange

func (bitmaps YearTradeBitmaps) SupportedYearRange() (minYear, maxYear int, ok bool)

SupportedYearRange 返回位图数据覆盖的年份范围。
