MACD Format, Triggers, Scan, Label, Watchlist For ThinkOrSwim

Can someone please help with this code, its just the default MACDHistogramCrossover code in TOS and I wanted to see if someone can modify the code to where it just shows the last 3 arrows instead of all the arrows on the chart, below is theMACDHistogramCrossover Code: Thank you

This will limit the plot of the arrows based upon the value of input arrow_limiter.

Is there any way to add that to a scan? I'd like to find stocks that are below the zero line (the horizontal purple line on the MACD).
 
Would like the candle colors on upper chart to be the same colors as this MACD Histogram script colors. Thanks a lot!

I have a scan using various parameters, but one more filter I'd like to add is to filter tickers where the MACDHistogram diff value of the last bar is less than the previous bar on a 5 minute timeframe (or greater, depending on what I'm scanning for) . I would specify either lower or higher in my scan depending on what I want to search
I'm using 12, 26, 9 exponential for my MACD (see screenshot for clarification)


KGfIi8A.png


I tried this in the scan, but that it gives me no results, so unsure if I'm doing this correctly:

Code: 
MACDHistogram()."Diff" is less than MACDHistogram()."Diff"

I already checked out this thread below, but that was related to the crossover

Your code looks for where the current bar is less than the current bar. The syntax for previous bar is: [1]
Code: 
MACDHistogram()."Diff" is less than MACDHistogram()."Diff"[1]
 
I would like to have an alert set up on ToS to notify me when the MACD line crosses above or below the zero line. Can someone help me with that?
 
Hello,

I am trying to paste that script in TOS, but I am getting error , not sure how to fix that.

Here's the script

Code: 
input price = close;
input macdFastLength = 12;
input macdSlowLength = 26;
input macdSignalLength = 9;


def macd = MACD(price, macdFastLength, macdSlowLength, macdSignalLength);


def longEntry = macd > high[1] and macd > macd[1];
def longExit = macd < low[1] or macd < macd[1];
def shortEntry = macd < low[1] and macd < macd[1];
def shortExit = macd > high[1] or macd > macd[1];

plot longSignal = longEntry;
plot shortSignal = shortEntry;

longSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_UP);
longSignal.SetLineWeight(3);
shortSignal.SetPaintingStrategy(PaintingStrategy.BOOLEAN_ARROW_DOWN);
shortSignal.SetLineWeight(3);


alert(longEntry, "Long entry signal", Alert.BAR, Sound.Ring);
alert(longExit, "Long exit signal", Alert.BAR, Sound.Ring);
alert(shortEntry, "Short entry signal", Alert.BAR, Sound.Ring);
alert(shortExit, "Short exit signal", Alert.BAR, Sound.Ring);

I am getting error at Line

Code: 
def macd = MACD(price, macdFastLength, macdSlowLength, macdSignalLength);

At MACD?

I do appreciate your help. Thanks.

when you get an error, look up the functions used in the formula.
you are trying to use the macd study and pass input parameters to it.

here is the macd study
https://tlc.thinkorswim.com/center/reference/Tech-Indicators/studies-library/M-N/MACD

look at the inputs, do you notice anything different in the parameters in your formula and the sequence of inputs in the manual?




macd doesn't have a price input parameter.

try removing price from the macd() function
so it looks like this,

def macd = MACD( macdFastLength, macdSlowLength, macdSignalLength);

Hi, looking for a MACD study that will signal with an arrow on my chart(upper).
I would like it to signal when the moving averages cross
any help would be great
 
Can someone code a signal arrow for when the histogram changes colors ex.... green to dark green and red to dark red?

you didn't say where you want to see something...


this plots a n arrow, on the upper chart, when the macd histogram changes color

Code: 
# macd_arrows

def na = double.nan;

# macd
input fastLength = 12;
input slowLength = 26;
input MACDLength = 9;
input averageType = AverageType.EXPONENTIAL;
input showBreakoutSignals = no;

def Value = MovingAverage(averageType, close, fastLength) - MovingAverage(averageType, close, slowLength);
def Avg = MovingAverage(averageType, Value, MACDLength);

def Diff = Value - Avg;
def ZeroLine = 0;


def up = (diff > diff[1]);
def dwn = (diff < diff[1]);

def dir = if up and Diff >= 0 then 2
     else if up and Diff <= 0 then 1
     else if dwn and Diff >= 0 then -1
     else if dwn and Diff <= 0 then -2
     else 0;

plot zup = if up and dir != dir[1] then low*0.999 else na;
plot zdwn = if dwn and dir != dir[1] then high*1.001 else na;

zup.SetPaintingStrategy(PaintingStrategy.arrow_up);
zup.SetLineWeight(3);
zup.AssignValueColor(if up and Diff >= 0 then color.green
  else if up and Diff <= 0 then color.dark_red
#  else if up and Diff <= 0 then color.yellow
  else color.gray);

zdwn.SetPaintingStrategy(PaintingStrategy.arrow_down);
zdwn.SetLineWeight(3);
zdwn.AssignValueColor(
  if dwn and Diff >= 0 then color.dark_green
#  if dwn and Diff >= 0 then color.cyan
  else if dwn and Diff <= 0 then color.red
  else color.gray);
#
 
Appreciate the quick response thank you
Didn't even think about putting on upper chart, maybe thats better. I'll give it a look when I get home

plotted this on my chart ... it looked like i spilled a bag of arrow skittles on my laptop screen lol. Not complaining it seemed like a good idea
one last request- can you code an arrow on curves? like when the MA line starts curve down or up?the arrow under the ma line when its starts to curve up and above it when curving down
 
I'm trying to add this MACD Script to use in a watchlist but it's not working when I copy and paste the script.
I found the steps to this script in a video on youtube

def fastlength = 12;

def slowlength = 26;

def MACDLength = 9;

def averageType = AverageType.EXPONENTIAL;

def showBreakoutSignals = no;

def ZeroLine = 0;



plot Value = MovingAverage (averageType, close, fastlength) – MovingAverage (averageType, close, slowlength);

plot Avg = MovingAverage (averageType, Value, MACDLength);



plot Diff = Value – Avg;



addlabel (yes, if value >= zeroline and avg >= zeroline and value crosses below avg within 3 bars then “Cross OB” else if value <= zeroline and avg <= zeroline and value crosses above avg within 3 bars then “Cross OS” else if value >= zeroline and avg >= zeroline and value > avg then “Bull Acc” else if
value >= zeroline and avg >= zeroline and value <avg then “Bull Dec” else if
value <= zeroline and avg <= zeroline and value < then “Bear Acc” else if

<= zeroline and avg <= zeroline and value > avg then “Bear Dec”

else
