help with EFS for Watchlist

[pj909]

Trying to use color coding to show a simple trend indicator based on MAs in a watchlist.

[PHP]
/************************************************** *******
Plot the trend on a watch list
************************************************** ********/
function preMain() {

setPriceStudy(true);
setDefaultBarBgColor(Color.lightgrey);
setShowTitleParameters(false)

// setPlotType(PLOTTYPE_LINE,0);
// setDefaultBarThickness(1,0);
// setPlotType(PLOTTYPE_LINE,1);
// setDefaultBarThickness(1,1);
// setDefaultBarFgColor(Color.blue,0);
// setDefaultBarFgColor(Color.red,1);
}

bInit = false;
var n50=0;
var n200 = 0;
var nPrc=0;
var rText=""

function main() {
if (!bInit) {
n50 = sma(50, 0);
n200 = sma(200, 0);
nPrc = close(0);
rText = "new Array(n50, n200)";
bInit = true;
}

if (nPrc > n50 && n50 > n200) {
setBarBgColor(Color.RGB(190,255,190), 0, nPrc);
setBarFgColor(Color.RGB(0,0,128));
rText = "new Array(n50, n200)";
} else if (nPrc < n50 && n50 < n200) {
setBarBgColor(Color.RGB(255,190,190), 0, 0, nPrc);
setBarFgColor(Color.RGB(128,0,0));
rText = "new Array(n200, n50)";
} else {
setBarFgColor(Color.darkgrey);
setBarBgColor(Color.lightgrey);
}


return eval(rText);
}

p.s. Been too long since I posted here. How do I get it format like a script?

Use the PHP tags ie [ PHP ] at the beginning and [ /PHP ] at the end of the code (without the spaces after the [ and before the ]) as in the example below
Alex

function preMain() {

setPriceStudy(true);
setStudyTitle("SMA");
setCursorLabelName("SMA",0);
setDefaultBarFgColor(Color.RGB(0x00,0x94,0xFF), 0);
setPlotType(PLOTTYPE_LINE,0);
setDefaultBarThickness(1,0);
}

function main() {

return sma(10);
}

Thanks Alex (had the / outside the brackets, duh).

/************************************************** *******

************************************************** ********/
function preMain() {

setPriceStudy(true);
setDefaultBarBgColor(Color.lightgrey);
setShowTitleParameters(false)

// setPlotType(PLOTTYPE_LINE,0);
// setDefaultBarThickness(1,0);
// setPlotType(PLOTTYPE_LINE,1);
// setDefaultBarThickness(1,1);
// setDefaultBarFgColor(Color.blue,0);
// setDefaultBarFgColor(Color.red,1);
}

bInit = false;
var n50=0;
var n200 = 0;
var nPrc=0;
var rText=""

function main() {
if (!bInit) {
     n50 = sma(50, 0);
     n200 = sma(200, 0);
     nPrc = close(0);
     rText = "new Array(n50, n200)";
bInit = true;
}

if (nPrc > n50 && n50 > n200) {
     setBarBgColor(Color.RGB(190,255,190), 0, nPrc);
     setBarFgColor(Color.RGB(0,0,128));
     rText = "new Array(n50, n200)";
} else if (nPrc < n50 && n50 < n200) {
     setBarBgColor(Color.RGB(255,190,190), 0, 0, nPrc);
     setBarFgColor(Color.RGB(128,0,0));
     rText = "new Array(n200, n50)";
} else {
     setBarFgColor(Color.darkgrey);
     setBarBgColor(Color.lightgrey);
}

return eval(rText);
} 

So is it possible to change the order (and color) of the return values?

If you want to color code a value in a Watchlist, it has to be done as a "return value" with a TAG.

You've commented out all of your OUTPUTS (or return values). This means you are trying to control colors of things that are not being returned by the script.

In other words, nothing returned means nothing gets color coded.

Try this...

/************************************************** *******
Plot the trend on a watch list
************************************************** ********/
function preMain() {

setPriceStudy(true);
setDefaultBarBgColor(Color.lightgrey);
setShowTitleParameters(false)

 setPlotType(PLOTTYPE_LINE,0);
 setDefaultBarThickness(1,0);
// setPlotType(PLOTTYPE_LINE,1);
// setDefaultBarThickness(1,1);
// setDefaultBarFgColor(Color.blue,0);
// setDefaultBarFgColor(Color.red,1);
}

bInit = false;
var n50=0;
var n200 = 0;
var nPrc=0;
var rText=""

function main() {
if (!bInit) {
     n50 = sma(50, 0);
     n200 = sma(200, 0);
     nPrc = close(0);
     rText = "new Array(n50, n200)";
bInit = true;
}

if (nPrc > n50 && n50 > n200) {
     setBarBgColor(Color.RGB(190,255,190), 0, nPrc);
     setBarFgColor(Color.RGB(0,0,128),0);
     rText = "new Array(n50, n200)";
} else if (nPrc < n50 && n50 < n200) {
     setBarBgColor(Color.RGB(255,190,190), 0, 0, nPrc);
     setBarFgColor(Color.RGB(128,0,0),0);
     rText = "new Array(n200, n50)";
} else {
     setBarFgColor(Color.darkgrey,0);
     setBarBgColor(Color.lightgrey,0);
}

return eval(rText);
} 

You have to use the TAG ID for the setBar.... color options to determine what is being colored.

Seeing as though you only have ONE return value (0), that is what we are trying to color.
