bar color not loading / reloading

[missionyam]

Hi

when i start esignal this efs does not take effect, nothing happens when i reload it, but if i remove it from a chart and then re-add it it works -

what do i need to do to make it active when i open esignal?

function preMain() {
setPriceStudy(true);
setStudyTitle("Color Bars");


var fp1 = new FunctionParameter("nFLen", FunctionParameter.NUMBER);
fp1.setName("FastEMA length");
fp1.setDefault(20);

var fp2 = new FunctionParameter("nSLen", FunctionParameter.NUMBER);
fp2.setName("SlowEMA length");
fp2.setDefault(200);
}

function main(nFLen, nSLen) {
var xStudyFast = ema(nFLen, ohlc4());
var xStudySlow = ema(nSLen, ohlc4());

//Long
if (close(0) > xStudyFast && xStudyFast < xStudySlow) {
setPriceBarColor(Color.RGB(163,192,0));

}
if (close(0) > xStudySlow && xStudyFast < xStudySlow) {
setPriceBarColor(Color.RGB(0,192,0));
}

if (close(0) > xStudyFast && xStudyFast > xStudySlow) {
setPriceBarColor(Color.RGB(0,128,0));
}


//Short
if (close(0) < xStudyFast && xStudyFast > xStudySlow) {
setPriceBarColor(Color.RGB(255,160,255));

}

if (close(0) < xStudySlow && xStudyFast > xStudySlow) {
setPriceBarColor(Color.RGB(255,87,192));
}

if (close(0) < xStudyFast && xStudyFast < xStudySlow) {
setPriceBarColor(Color.red);
}

return;

Re: bar color not loading / reloading

As is the formula is giving a syntax error which is caused by a missing closing curly bracket } after the return statement
I suppose that is just a typo since you indicate that the formula is working at your end although - assuming I understood you correctly - it is not coloring the price bars.
If that is the case then the reason is that in the preMain() function you omitted to add the following statements

setColorPriceBars(true);
setDefaultPriceBarColor(Color.your_default_color); 

which are required when using the setPriceBarColor() function (for reference see this article in the EFS KnowledgeBase)
