Tweezer candlestick pattern in ThinkorSwim

[Buckbull]

Is Anyone familiar with making your own candlestick pattern study ? Im trying to set up a bottoming tail on one study and a topping tail on another . Any pointers ?

 

[tomsk]

@Buckbull If you are not already aware you might like to know that TOS has a library of candlestick patterns available.
Just go to the TOS platform, click on charts. Then on the top right, there is a button called "Patterns"
There is a drop down menu, so you can go and explore that area. Many examples of chart of candlestick patterns there

 

[Buckbull]

No specific pattern named bottoming tail , guess i could use a hammer and inverted . But i wanted a long tail and smaller body

 

[Buckbull]

Just made my own tweezer top and bottom came out great but cant figure how to make a small body and long tail

 

[BenTen]

@Buckbull If you want to create a more advanced candlestick pattern, you would have to write your own script for that. The default editor is still great for beginners to get started, though. Glad to hear about your tweezer top and bottom.

 

[Buckbull]

Ben Can you please check them out see if you would change anything I think they are good

Tweezer Top

# Generation time: 2020-12-09T00:55:57.031Z

def IsUp = close > open;
def IsDown = close < open;
def IsDoji = IsDoji();
def avgRange = 0.05 * Average(high - low, 20);
plot PatternPlot =
    IsUp[1] and
    IsDown[0] and
    Between(open[1] - close[0], -avgRange, avgRange) and
    close[1] == open[0];

PatternPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_WEDGE_DOWN);
PatternPlot.SetDefaultColor(GetColor(0));

Tweezer Bottom

# Generation time: 2020-12-09T00:56:49.012Z

def IsUp = close > open;
def IsDown = close < open;
def IsDoji = IsDoji();
def avgRange = 0.05 * Average(high - low, 20);
plot PatternPlot =
    IsDown[1] and
    IsUp[0] and
    Between(open[1] - close[0], -avgRange, avgRange) and
    close[1] == open[0];

PatternPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_WEDGE_UP);
PatternPlot.SetDefaultColor(GetColor(0));

Im trying to do something like this the doesnt have to be a Super Bottoming tail but something with a small body and a long tail

 

[Buckbull]

@tomsk Could you by any chance help me out , with the pinbar study ben posted i would like to do a scan where the pinbar closes within the body of the previous days candle . Thanks

@Buckbull - I assume you're referring to the Pinbar indicator that @BenTen posted in the following thread

https://usethinkscript.com/threads/pin-bar-reversal-indicator-for-thinkorswim.156/
Here is your COMPLETED scan. Load the following code directly into the scanner. It scans for a bullish/bearish pinbar that closes within the body of the previous days candle. Please note that I have NOT changed any of the definitions of the pinbar definition that came with the original study
I just added your requirement for closes within the body of the previous candle and some minor clean up to enable the scan.

I have tested the scan on the S&P 500. At the present time, a bullish scan yields 2 results while a bearish scan yields 1 result.

input LastBars = 0;

input NoseBodyPosition = 0.4; #(default = 0.4) — Nose body should be position in top (bottom for bearish pattern) part of the Nose bar.
input LeftEyeOppositeDirection = yes; #(default = true) — tells the indicator that the Left Eye bar should be bearish for bullish Pinbar, and bullish for bearish Pinbar.
input NoseSameDirection = yes; #(default = true) — tells the indicator that the Nose bar should be of the same direction as the pattern itself.

[Buckbull]

Awesome thanks as usual , But Im a little confused if im saving it right when I copied the script you made in I got 2 stocks like you did
$REG
$MKC
How do I switch it to a Bearish Scan ?

 

[horserider]

Bullish scan

# Comment out (#) the ONE not needed

plot bullish_signal = BullSignalup and condition;
# plot bearish_signal = BearSignalDown and condition;

# End Pinbar Scan

Bearish Scan

# Comment out (#) the ONE not needed

# plot bullish_signal = BullSignalup and condition;
plot bearish_signal = BearSignalDown and condition;

# End Pinbar Scan

I would just save as different scans.

You seem to be new to scans - please note that the scanner only accepts one plot statement
I have listed two in the code, one commented out. Just switch those round for theopposite case

You should get 1 result for the bearish case if you ran the scan today

 

[Buckbull]

@tomsk I am new, but i will learn it . I refuse to be beat!

Not to worry, with practice you'll get the hang of it in no time!

Very easy to do using the TOS candlestick pattern editor.

Here is an example:

Two consecutive green candles.

# Generation time: 2021-05-06T02:20:32.449444600Z

def IsUp = close > open;
def IsDown = close < open;
def IsDoji = IsDoji();
def avgRange = 0.05 * Average(high - low, 20);
plot PatternPlot =
    IsUp[1] and
    IsUp[0];

PatternPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_POINTS);
PatternPlot.SetDefaultColor(GetColor(0));

 

[horserider]

@Buckbull I thought a tweezer top or bottom happens in a trend. Do your studies include this?
And be aware a tweezer can also be a trend continuation signal I believe approximately half the time.
Hope my memory is not betraying me on this.

Tweezer Top

# Generation time: 2020-12-09T00:55:57.031Z

def IsUp = close > open;
def IsDown = close < open;
def IsDoji = IsDoji();
def avgRange = 0.05 * Average(high - low, 20);
plot PatternPlot =
    IsUp[1] and
    IsDown[0] and
    Between(open[1] - close[0], -avgRange, avgRange) and
    close[1] == open[0];

PatternPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_WEDGE_DOWN);
PatternPlot.SetDefaultColor(GetColor(0));

Tweezer Bottom

# Generation time: 2020-12-09T00:56:49.012Z

def IsUp = close > open;
def IsDown = close < open;
def IsDoji = IsDoji();
def avgRange = 0.05 * Average(high - low, 20);
plot PatternPlot =
    IsDown[1] and
    IsUp[0] and
    Between(open[1] - close[0], -avgRange, avgRange) and
    close[1] == open[0];

PatternPlot.SetPaintingStrategy(PaintingStrategy.BOOLEAN_WEDGE_UP);
PatternPlot.SetDefaultColor(GetColor(0));

Can you post a picture of what this is supposed to look like when it finds one please?
