MorningStar

Description

The Morning Star pattern is the converse of the Evening Star pattern. The Morning Star is a bottom reversal pattern, so bearish trend confirmation is important.

The Morning Star is a three candlestick pattern:

Ideally, the first, white bar is has a long black body. The second candlestick gaps down and has a small real body--ideally, no real body (Doji). The third candlestick has a white body that penetrates well into the first day's black real body. If the third candlestick gaps up, an Abandoned Baby pattern (Island Bottom) emerges.

Formula

MorningStar(INPUT, Stringency=8, LRRange=10, LRType=3, SmallForm=10)=begin

  retval = NONUM

  targetBar = 0

  pnt0 = targetBar

  pnt1 = targetBar + 1

  pnt2 = targetBar + 2

  ppClose = GetPrice($1, BATE_CLOSE, pnt2, 0)

  ppLow = GetPrice($1, BATE_LOW, pnt2, 0)

  pOpen = GetPrice($1, BATE_OPEN, pnt1, 0)

  pClose = GetPrice($1, BATE_CLOSE, pnt1, 0)

  pHigh = GetPrice($1, BATE_HIGH, pnt1, 0)

  cOpen = GetPrice($1, BATE_OPEN, targetBar, 0)

  if WhiteBody($1, pnt0) == TRUE AND BlackBody($1, pnt2) == TRUE then begin

    if Stringency >= 8 then retval = '8'|clr_green|below|ftiny|arrow|vertical

    if pOpen <= ppClose then begin

      if Stringency >= 7 then retval = '7'|clr_green|below|ftiny|arrow|vertical

      if cOpen > pClose then begin

        if Stringency >= 6 then retval = '6'|clr_green|below|ftiny|arrow|vertical

        if SmallRealBody($1, pnt1, SmallForm) then begin

          if Stringency >= 5 then retval = '5'|clr_green|below|ftiny|arrow|vertical

          if cOpen > pHigh then begin

            if Stringency >= 4 then retval = '4'|clr_green|below|ftiny|arrow|vertical

            if LongBlackForm($1, pnt2) OR DojiForm($1, pnt1) OR LongWhiteForm($1, pnt1) then begin

              if Stringency >= 3 then retval = '3'|clr_green|below|ftiny|arrow|vertical

              if LongWhiteForm($1, pnt1) then begin

                if Stringency >= 2 then retval = '2'|clr_green|below|ftiny|arrow|vertical

                if Bearish($1, pnt2, LRRange, LRType) == TRUE then begin

                  retval = 'Morning Star'|clr_black|below|ftiny|arrow|vertical

                end

              end

            end

          end

Parameters

INPUT

The INPUT directive makes this formula available as a Formula Overlay. INPUT refers to the instrument in the chart.

Stringency

The Stringency argument is used by nearly all candlestick overlays. It controls how many tests must pass in the evaluation of a Morning Star. The lower the number, the more strict the interpretation.

The Stringency argument is an overlay parameter. You can adjust it using the Parameters dialog. The default is 8.

LRRange

The MorningStar overlay uses the LR() function with either a continuous or quadratic calculation to determine how the market is trending. The LRRange (Linear Regression Range) parameter is the number of points in the Linear Regression calculation. The default is 10.

LRType

The LRType parameter has two possible settings: 2 and 3, or continuous linear regression and quadratic linear regression, respectively. The default is 3, or quadratic.

SmallForm

The SmallForm parameter represents a percentage. This parameter serves as the basis for determining whether a candlestick is Doji or near Doji. The smaller the value assigned to SmallForm the more stringent the test. The default is 15, or fifteen percent.

Return Value

The return value is a string plot and varies depending on the value of the Stringency parameter.  The lower the number, the stronger the pattern.

Bullish indicators are rendered in green below the candlestick.

The string plot for a fully qualified Morning Star is "Morning Star" rendered in black below the candlestick.
