Hi

I would like to modify the standard ema in esignal so so it changes colour if the price is above to if its below in realtime.

function preMain() {
    setPriceStudy(true);
}

var dLastMA = 0.0;
var dThisMA = 0.0;
var dPercent = 0.0;
var dCount = 0;
var bPrimed = false;


function main(nInputLength) {
    if(nInputLength == null)
        nInputLength = 50;

	var nBarState = getBarState();
    var i;
	var dValue;
	var dSum = 0.0;

	if(nBarState == BARSTATE_ALLBARS) {
		// reset!
		dPercent = (2.0 / (nInputLength + 1.0));
		dLastMA = 0.0;
		dThisMA = 0.0;
		dCount = 0;
	}

	if(nBarState == BARSTATE_NEWBAR) {
		dLastMA = dThisMA;
	}
	dThisMA = dLastMA;

	if(bPrimed == false) {
	    dValue = getValue("Close", 0, -nInputLength);
		if(dValue == null)
			return;

	    for(i = 0; i < nInputLength; i++) {
		    dSum += dValue[i];
	    }

		dLastMA = dSum / nInputLength;
		dThisMA = dLastMA;

		bPrimed = true;
	} else {
		dValue = getValue("Close");
		if(dValue == null)
			return;

		dThisMA = (dValue - dLastMA) * dPercent + dLastMA;
	}


	return dThisMA;

}

I would like it to be bue if the price is above and red if the price is below, can you help please?

Thanks
