This indicator helps spot Gravestone Doji candle, Hammer bar, and a few other reversal candlestick patterns in ThinkorSwim. The full list can be mentioned below.

Candlestick reversal patterns included in this indicator:
  • Gravestone Doji Candle (Reversal possible on Gravestone Doji)
  • HammerBar (Reversal possible on Hammer Doji)
  • ReversalLikelyBar
  • stopVolBar (Stopping Volume at Lows indicates Downtrend end likely)
  • stopVolBarHighs (Stopping Volume at Highs indicates Uptrend end likely)
  • StrengthConfirmationBar (Strength confirmed on UpBar)
  • StrengthConfirmationBar2 (Strength confirmed on UpBar closing Near High)
  • PseudoUpThrustBar (Weakness on Pseudo-UpThrust)
  • pseudoUpThrustConfirmation (Weakness confirmed on DownBar closing Down after PseudoUpThrust)
  • strengthInDownTrend (Strength returning in Downtrend)
  • strengthInDownTrend1 (Strength returning on High Volume in Downtrend)
  • strengthInDownTrend2 (Strength on High-volume UpBar closing on High)
I found these reversal candles to be helpful especially at critical support and resistance levels. Other patterns have been commented out within the code.

Rich (BB code): 
# This is a conversion of the NinjaTrader VPA indicator.  ToS does not support directional
# triangles and diamonds, so there are some differences.  The triangles are left as is, just
# not pointing a specific direction.  The diamonds have been replaced with circles.

# C_RP Original notes by cbritton are above. Changes made after 20100722 by Richard Paske are marked below by the C_RP comment tag. A few bugs were fixed. More significantly, the color scheme for symbols was changed radically in an attempt to map directional strength to hue based on the ROYGBIV color spectrum. In addition, a symbol's shape and its vertical position above or below a candle now imparts added meaning to it. In general, the strength of a symbol is assigned by its color and shape in that order. In certain circumstances a symbol's vertical offset from its candle's top or bottom strengthens the symbol's meaning. The symbol strength  hierarchy is defined as follows:

# 1. Color: Symbols below candles are assigned strength from weakest to strongest in this order: white (or grey), cyan (blue/green), green. A red symbol under a candle indicates the failure of the symbol attached below the candle immediately preceding it.
# Symbols above candles are assigned strength from weakest to strongest in this order: yellow, orange, red. A green symbol above a candle indicates the failure of a symbol attached above the candle immediately preceding it. A magenta (pinkish purple) square above a candle is a special case indicating Distribution. Another special case for testing purposes as of 20100830 is a white triangle high above a candle indicating a Gravestone Doji.
# Symbols drawn on the middle of a candle are of two types with one variation. A green circle indicates Effort to Move Up on up bars. A magenta (pinkish purple) circle indicates Effort to Move Down on down bars except for red down bars on which magenta displays poorly. In order to be seen easily, yellow circles indicate Effort to Move Down on red down bars.

# 2. Shape: A symbol of a given color is assigned increasing strength according to this hierarchy (from low to high): circle, square, triangle, downward or upward arrow. In certain circumstances two symbols of the same shape and color will be stacked vertically, adding strength through the combined symbols. Occasionally, two different symbols will be stacked vertically because that candle satisfies the criteria for two indications.

# Listed below are the symbols and their meanings. The original symbol chart can be found at the end of this study.

# ___Symbols Below Candles___
# White Square - Test for Supply
# Cyan Circle - No Supply
# Cyan Triangle - Successful Test for Supply
# 2 Cyan Triangles - Successful Test for Supply 2

# Grey Square - Test for Supply in Uptrend

# Green Circle - Stopping Volume

# Cyan Square - Strength in Downtrend
# Green Square - Strength in Downtrend 1
# Green Triangle - Strength in Downtrend 2
# Green UpArrow - Strength Confirmation Bar
# 2 Green UpArrows - Strength Confirmation Bar with High Close
# Red Square - Failed Strength Signal

# ___Symbols in the Middle of Candles___
# Green Circle - Effort to Move Up
# Magenta Circle - Effort to Move Down
# Yellow Circle - Effort to Move Down on Red Down Candles

# ___Symbols Above Candles___
# White Triangle - Gravestone Doji (included as an experiment as of 20100830 to test its usability in the UpThrust category)
# Yellow Triangle - Weakness

# Orange Circle - No Demand
# Orange Square - PseudoUpThrust
# Orange Triangle - PseudoUpThrust Confirmation

# Red Square - UpThrust
# Red Triangle - Confirmed UpThrust Condition 1
# Red DownArrow - Confirmed UpThrust Condition 2 or 3
# Green Square - Failed UpThrust or PseudoUpThrust Confirmation

# Red Circle - Reversal Likely
# Magenta Square - Distribution
# Magenta Triangle - Two or Three Period UpThrust

# C_RP The next two comments are from the original comments by cbritton.
# The NT version used a LinRegSlopeSFX indicator for determining trends. Those have been
# replaced in this ToS version with a call to the built in LinearRegressionSlope indicator.
# Changes made after 20120922 by Glenn Kaler are marked below by the C_GK comment tag.
# C_GK TOS removed AddChartLabel and replaced it with AddLabel. Rationale: Using "Chart" in AddChartLabel was unnecessary since this function only relates to charts.

This is an awesome indicator, thank you. I am toying with the combination of it and the Trend Reversal indicator. So far so good.
 
Hi all I came across the bullish Doji star script by @Jynx and i Decided to try and add a bearish doji star to the code, Attached is the code, this is my first attempt at coding something using thinkScript so Im not 100% it looks correct in TOS so if anyone could take a look at it. It is essentially @Jynx code but I reversed the numbers in hope that it works right.
Thank You

Code: 
input downtrendSetup = 6; #Number of bars to calculate downtrend slope...not all of these bars have to be descending as long as the overall value is neg it is descending

input shadowFactor = 1; #size of tail in relation to body  higher number less signals can be like .50 for more signals just not below zero or zero


assert(shadowFactor >0, "'shadow factor' must not be negative or zero: " + shadowFactor);

def BodyHeight = BodyHeight();

plot Bullish = IsDescending(close, downtrendSetup) and low<low[1] and low[1]<low[2] and low[2]<low[3]
    and
    Min(open, close) - low > shadowFactor * BodyHeight;
plot Bearish = IsAscending(close, downtrendSetup) and low > low[1] and low [1] > low[2] and low[2] > low[3]
    and
    Min(open,close) - low < shadowFactor * BodyHeight;
Bullish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
Bullish.SetDefaultColor(GetColor(4));
Bullish.SetLineWeight(2);
Bearish.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
Bearish.setDefaultColor(GetColor(6));
Bearish.setLineWeight(2);
 
i have this script that turns yellow when there is a bull flag or orange when there is a bearflag. is there anyway to make something like this for Doji candles? script below of the bear and bull flag

Code: 
#To use for scan place # signs before 2 Addlabel statements and change "def" before trigger statement to "plot"
##############Bull Flag
def StockPrice = close>=10;
def trend = simpleMovingAvg("length"=30)> (simpleMovingAvg("length"=30)[5]);
def MacdLow = macdHistogram(8,17,9)[1]< macdHistogram(8,17,9)[2]and close[1]<close[2] and close>high[1];
#def Momentum = macdHistogram(8,17,9) > macdHistogram(8,17,9)[1];
##############Bear Flag
def StockPriceBear = close>=10;
def trendBear = simpleMovingAvg("length"=30)< (simpleMovingAvg("length"=30)[5]);
def MacdHighBear = macdHistogram(8,17,9)[1]> macdHistogram(8,17,9)[2]and close[1]>close[2] and close<low[1];
#########################################
#def trigger = trend and momentum and MacdLow;
def Bulltrigger = trend and MacdLow;
def BearTrigger = TrendBear and MacdHighBear;

#AddLabel(yes, if Bulltrigger then "Bull Flag" else " ",Color.PLUM);
AddLabel(yes, if Bulltrigger then "Bull Flag" else if BearTrigger then "Bear Flag" else " ",Color.black);
AssignBackgroundColor(if Bulltrigger then color.YELLOW else if bearTrigger then color.LIGHT_RED else color.WHITE);

I`ve searched the forum for a study that looks for a specific doji candle, namely the long legged that consists of long upper and lower shadows and has approximately the same opening and closing price (see pic below) but havn`t found any such. So i am wondering if anyone has a study for this that gives signals on the chart when these candles appear and i should also mention that it's intended to be used on Heiken Ashi candle type charts.

Would it be possible to make a study for this specific candle type?

@zeek Hey did you ever find code for this?
I'm trying to build an indicator and can't find it so far. mikegfel

As long as you use regular candles, the built in pattern study works for finding this specific doji candle but if you use Heiken Ashi it won`t work like i wrote in my previous posts. And no, i havn´t found any other code that will make this work with HA charts unfortunately..
