Dynamic Monthly Pivot Points

[muecke]

Hello,

I would like to modify the following efs called "Monthly Pivot Points" (by Alex Montenegro) in a way that it calculates and plots these monthly levels based on the following datapoints:
Highest High of the past 3 months
LowestLow of the past 3 months
and the current months close.

And got no idea how to do that.......


function preMain() {
setPriceStudy(true);
setStudyTitle("Monthly Pivot Points");
setCursorLabelName("PP-R2", 0);
setCursorLabelName("PP-R1", 1);
setCursorLabelName("PP", 2);
setCursorLabelName("PP-S1", 3);
setCursorLabelName("PP-S2", 4);
// R2
setDefaultBarStyle(PS_DASH, 0);
setDefaultBarFgColor(Color.RGB(255,0,0), 0);
setDefaultBarThickness(2, 0);
// R1
setDefaultBarStyle(PS_DOT, 1);
setDefaultBarFgColor(Color.RGB(0,0,255), 1);
setDefaultBarThickness(1, 1);
// Pivot Point
setDefaultBarStyle(PS_SOLID, 2);
setDefaultBarFgColor(Color.RGB(0,0,0), 2);
setDefaultBarThickness(1, 2);
// S1
setDefaultBarStyle(PS_DOT, 3);
setDefaultBarFgColor(Color.RGB(0,0,255), 3);
setDefaultBarThickness(1, 3);
// S2
setDefaultBarStyle(PS_DASH, 4);
setDefaultBarFgColor(Color.RGB(255,0,0), 4);
setDefaultBarThickness(2, 4);
}

var bInit = false;
var xHigh = null;
var xLow = null;
var xClose = null;
var vPP = null;
var vR1 = null;
var vS1 = null;
var vR2 = null;
var vS2 = null;

function main() {

if(bInit == false){
xHigh = high(inv("M"));
xLow = low(inv("M"));
xClose = close(inv("M"));
bInit = true;
}

var vHigh = xHigh.getValue(-1);
var vLow = xLow.getValue(-1);
var vClose = xClose.getValue(-1);
if(vHigh == null || vLow == null || vClose == null)
return;

vPP = (vHigh+vLow+vClose)/3;
vR1 = 2*vPP-vLow;
vS1 = 2*vPP-vHigh;
vR2 = (vPP-vS1)+vR1;
vS2 = vPP-(vR1-vS1);

return new Array(vR2, vR1, vPP, vS1, vS2);
}

Anybody can help?

Thanks

Can nobody help?

Still need help on my Pivot.efs

I am trying to create this Pivots using the 3-month High, Low. Close. Used a Call-efs-function, have no idea if I am on the right track............just can't get it to work
here is the file:


function preMain() {

setPriceStudy(true);
setStudyTitle("Dynamic Pivots Monthly");
setCursorLabelName("R2", 0);
setCursorLabelName("R1", 1);
setCursorLabelName("PP", 2);
setCursorLabelName("S1", 3);
setCursorLabelName("S2", 4);
setDefaultBarFgColor(Color.RGB(255,255,0), 0);
setDefaultBarFgColor(Color.RGB(255,255,0), 1);
setDefaultBarFgColor(Color.RGB(255,255,0), 2);
setDefaultBarFgColor(Color.RGB(255,255,0), 3);
setDefaultBarFgColor(Color.RGB(255,255,0), 4);
setDefaultBarThickness(2, 0);
setDefaultBarThickness(2, 1);
setDefaultBarThickness(2, 2);
setDefaultBarThickness(2, 3);
setDefaultBarThickness(2, 4);
setPlotType(PLOTTYPE_DOT,0);
setPlotType(PLOTTYPE_DOT,1);
setPlotType(PLOTTYPE_FLATLINES,2);
setPlotType(PLOTTYPE_DOT,3);
setPlotType(PLOTTYPE_DOT,4);


}

var vOpen = null;
var vOpen1 = null;
var vHigh = null;
var vHigh1 = null;
var vLow = null;
var vLow1 = null;
var vClose1 = null;

var vPP = null;
var vR1 = null;
var vR2 = null;
var vS1 = null;
var vS2 = null;



function main() {
var vTime = getValue("time");//create date object using bar time
var vData = callFunction("/OHLC/getPrevMonthsOHLC.efs", "Open", "High", "Low", "Close", -2, 2);
if (vData == null) return;
return vData;



if (close(-1)==null)
return;

if(getBarState()==BARSTATE_NEWBAR&&getMonth()!=get Month(-1)) {
vHigh1 = vHigh;
vLow1 = vLow;
vClose1 = call("/OHLC/getPrevMonthsOHLC.efs", "Close");//comment out this line if using alternate vClose1
vHigh = high();
vLow = low();
}

if (vHigh == null)
vHigh = high();
if (vLow == null)
vLow = low();


vHigh = Math.max(high(), vHigh);
vLow = Math.min(low(), vLow);


//alternate vClose1 if one wants to use the daily bar Close. NOTE that this will not work with Tick Replay
//vClose1 = call("/OHLC/getPrevOHLC.efs", "Close");

//for alternative Pivots that require today's Open use vOpen in the Pivot calculations


vPP = (vHigh1 + vLow1 + vClose1) / 3;
vR1 = 2 * vPP - vLow1;
vR2 = vPP + vHigh1 - vLow1;
vS1 = 2 * vPP - vHigh1;
vS2 = vPP - vHigh1 + vLow1;


if (vOpen1 == null || vLow1 == null || vHigh1 == null || vClose1 == null) {
return;
} else {
return new Array(vR2,vR1,vPP,vS1,vS2);
}
}




I would really appreciate your help

I am using the below code to use Yesterdays close instead of last month close for Monthly Pivots. However the script is not recognizing the call function and nothing is being plot

//alternate vClose1 if one wants to use the daily bar Close. NOTE that this will not work with Tick Replay
vClose1 = call("/OHLC/getPrevOHLC.efs", "Close");

muecke,

Here is my take on your request. You will have to determine if it is what you are asking for. The code is commented.
NOTE: You may also find useful monthly pivots in the eSignal ".../Formulas/Pivots" folder.
