Good morning:
I am attempting to write a PCF for a custom MACD indicator where I will get hits as the MACD line passes through in a downward direction through the trigger linewhich of course is the moving average of the MACD line. The PCF to accomplish this has three main components but to keep things simple I will only describe the first two.
Part 1. (XAVGC3-XAVGC6)> 0 AND....this works and in English assures the
difference in the three day exponential and six day exponential
moving average is greater than Ɔ'. Or the MACD is always
greater than zero (0).
Part 2. (XAVG(XAVGC3,4-XAVGC6,4)) > (XAVGC3-XAVGC6) AND....this doesn't
work. In English this part of the equation is to
assure the trigger line, the four (4) day
exponential moving average of the MACD line is
always greater > than the MACD line. I suspect
some syntax violation or bogus averaging taking
place. I have been working on the for three days
without success.
Please advise me where the problem is.
Thank you.
Respectfully,

QUOTEPart 2. (XAVG(XAVGC3,4-XAVGC6,4)) > (XAVGC3-XAVGC6)
In PCF language you cannot do an average of a fuction. The formula below will take care of this:
(XAVG(XAVGC3,4)-XAVG(XAVGC6,4)) > (XAVGC3-XAVGC6)

I have a custom Macd . It's basis is 3,22,100 . When I put this into the tele chart it doesn't look the same. When I went back to get a breakdown of its actual formula I got:
var vMACD = null;
function preMain() {
setStudyTitle("MACD");
setCursorLabelName("MACDHist",0);
setCursorLabelName("MACD",1);
setCursorLabelName("MACDSig",2);
setDefaultBarFgColor(Color.black,0);
setDefaultBarFgColor(Color.white,1);
setDefaultBarFgColor(Color.white,2);
setDefaultBarThickness(3,0);
setDefaultBarThickness(1,1);
setDefaultBarThickness(1,2);
setPlotType(PLOTTYPE_LINE);
addBand(0, PS_SOLID, 2, Color.black, "0");
var fp1 = new FunctionParameter("Fast", FunctionParameter.NUMBER);
fp1.setLowerLimit(1);
fp1.setDefault(3); //Edit this value to set a new default
var fp2 = new FunctionParameter("Slow", FunctionParameter.NUMBER);
fp2.setLowerLimit(1);
fp2.setDefault(22); //Edit this value to set a new default
var fp3 = new FunctionParameter("Smoothing", FunctionParameter.NUMBER);
fp3.setLowerLimit(1);
fp3.setDefault(100); //Edit this value to set a new default
var fp4 = new FunctionParameter("Source", FunctionParameter.STRING);
fp4.setName("Source");
fp4.addOption("Close");
fp4.addOption("High");
fp4.addOption("Low");
fp4.addOption("Open");
fp4.addOption("HL/2");
fp4.addOption("HLC/3");
fp4.addOption("OHLC/4");
fp4.setDefault("Close"); //Edit this value to set a new default
var fp5 = new FunctionParameter("TypeOsc", FunctionParameter.BOOLEAN);
fp5.setName("SMA (Oscillator)");
fp5.setDefault(false); //Edit this value to set a new default
var fp5 = new FunctionParameter("TypeSig", FunctionParameter.BOOLEAN);
fp5.setName("SMA (Signal)");
fp5.setDefault(false); //Edit this value to set a new default
}
function main(Fast, Slow, Smoothing, Source, TypeOsc, TypeSig) {
if (vMACD == null) vMACD = new MACDStudy(Fast, Slow, Smoothing, Source, TypeOsc, TypeSig);
/*********************************************
Insert your code following this text block
Use vMACD.getValue(MACDStudy.HIST) and
vMACD.getValue(MACDStudy.MACD) and
vMACD.getValue(MACDStudy.SIGNAL) for your code
**********************************************/
return new Array (vMACD.getValue(MACDStudy.HIST),vMACD.getValue(MACDStudy.MACD),vMACD.getValue(MACDStudy.SIGNAL));
}
I am not a programmer so I am not able to put this into easyscan language . Can u help me ? Thanks

Where did this come from? Do you know what the indicator does? Is there a plain-language explanation that you can share that compelled you to start using it?
I am unable to translate the above....
What does the indicator do?

It is a Macd indicator they call T1 Macd Hist.efs. I Was using it from esignal. It seems to help signify the topping or bottoming pressure of a stock.
I also have a pg for esig i could send

also it is supposed to be a Macd histogram charting as a line rather than a vertical charting method. I could send u the attachment I have , to your email address.

Craig,
Your PCF is correct, but TC2K does not evaluate it correctly. Write it as:
(XAVG(XAVGC4,3)-XAVG(XAVGC6,4)) > (XAVGC3-XAVGC6)
and it will be correctly evaluated.
If you wish to see just how bad the problem can be, bring up GE and:
Top Window:
Custom Indicator:
Plot using price scale: Check
Indicator Formula: XAVG(XAVGC3,15)
and, also:
Top Window:
Custom Indicator:
Plot using price scale: Check
Indicator Formula: XAVG(XAVGC15,3)
They should overlay one another.
You will not encounter the problem if you always write:
XAVG(XAVGCP,Q)
with
Q <= P
Of course, the problem should be fixed.
Thanks,
Jim Murphy

In reference to my previous post of 2/21 on the long winded Macd. I was wondering if it possible to have up to 5 variants in a Macd ?
I see the First 3 Function Parameters are 3,22,100. respectively .
Then it seems to have a 4th one that has a mixture of Open , High , low ,close for the 1st 4 options on it and a "HL/2" then a "HLC/3", "OHLC/4" and a final Default "Close"
Could this be an 8-way average for the 4th Function parameter ?
Then there is a 5th Function parameter as an Sma ?

I've looked over the code you posted above and still have no idea what it is trying to do.
Where did this come from? Where is the plain-English description of the indicator that makes you want to use it? What is it supposed to do?
I assume you read something that described the indicator before you felt you needed to use it. Share that with me and I might be able to figure out the monster.

I received that T1 Macd from the trader below. I've been using it as an efs page formula thru esignal . But I have not been able to get in touch with her since.

I wish I could help you more. I am not familiar with the language your indicator is written in so I cannot translate it. Perhaps someone else on the boards is familiar with the language and can traslate it for us
