Hi,
I'm also looking for a QQE indicator for Zorro.
MetaTrader coding is not a simple task.
Yesterday I found a QQE version for Amibroker.
I will try to convert it to Zorro.

QQE_Periods = 14;
QQE_SF = 5;

QQE_RSI_MA = EMA(RSI(QQE_Periods),QQE_SF);
QQE_ATR_RSI = abs(Ref(QQE_RSI_MA,-1)-QQE_RSI_MA);
QQE_MA_ATR_RSI = EMA(QQE_ATR_RSI, 2*QQE_Periods-1);
QQE_DAR = EMA(QQE_MA_ATR_RSI, 2*QQE_Periods-1)*4.236;
QQE_DAR_Fast = EMA(QQE_MA_ATR_RSI, 2*QQE_Periods-1)*2.618;

function QQE_TR(RSIMA, DARFACTOR)
{
result[0] = 0;
for(i=1; i<BarCount; i++)
{
if(RSIMA[i] < result[i-1])
{
result[i] = RSIMA[i]+DARFACTOR[i];
if((RSIMA[i-1] < result[i-1]) AND (result[i] > result[i-1]))
{
result[i] = result[i-1];
}
}
else
{
if(RSIMA[i] > result[i-1])
{
result[i] = RSIMA[i]-DARFACTOR[i];
if ((RSIMA[i-1] > result[i-1]) AND (result[i] < result[i-1]))
{
result[i] = result[i-1];
}
}
}
}
return result;
}

QQE_FastSignal = QQE_TR(QQE_RSI_MA,QQE_DAR_Fast);
QQE_SlowSignal = QQE_TR(QQE_RSI_MA,QQE_DAR);

Plot(QQE_RSI_MA,"QQE"+_PARAM_VALUES(),ParamColor("QQE color",colorRed),ParamStyle("QQE style",styleThick));
Plot(QQE_FastSignal,"FastSignal",ParamColor("FastSignal color",colorOrange),ParamStyle("FastSignal style",styleDashed));
Plot(QQE_SlowSignal,"SlowSignal",ParamColor("SlowSignal color",colorBlue),ParamStyle("SlowSignal style",styleDashed));
