簡單指標就能定義波段多空..指標是很客觀，關鍵在於人的貪與懼

何苦四處找尋?

====================================

Parameter: Price(Close), Length(20), UpMultiplier(2.0), DnMultiplier(-2.0)
Variables: BBTop(0), BBBot(0), BandWidth(0), BBMid(0)

Value1 = MAFC(Price, Length)
Value2 = StdDev(Price, Length)

BBTop = Value1 + UpMultiplier * Value2
BBBot = Value1 + DnMultiplier * Value2
BBMid = Value1

BandWidth = (BBTop-BBBot) / BBMid * 100

Draw1(BandWidth, "BandWidth")
