Hello,

For those using this indicator to trade, it may be useful to know in advance at which price the MACD will cross its signal line. Please find the code here below. If someone knows how to draw text on the right hand of the chart and not on the last candle, please shoot.
```
defparam drawonlastbaronly=true

ONCE FastAvg = 12
ONCE SlowAvg = 26
ONCE SigAvg  = 9

EMAshort1 = exponentialaverage[FastAvg](close)
EMAshort2 = exponentialaverage[FastAvg](EMAshort1)
DifferenceShort = EMAshort1 - EMAshort2
ZeroLagShort = EMAshort1 + DifferenceShort

EMAlong1 = exponentialaverage[SlowAvg](close)
EMAlong2 = exponentialaverage[SlowAvg](EMAlong1)
DifferenceLong = EMAlong1 - EMAlong2
ZeroLagLong = EMAlong1 + DifferenceLong

ZeroLagMACD = ZeroLagShort - ZeroLagLong

signal1=ExponentialAverage[SigAvg](ZEROLAGMACD)
signal2=ExponentialAverage[SigAvg](signal1)
DIFFERENCE2=signal1-signal2

SignalMACD=signal1+DIFFERENCE2


alphaX=2/(1+FastAvg)
alphaY=2/(1+SlowAvg)
prevEMA1=ZeroLagShort[1]
prevEMA2=ZeroLagLong[1]



macdValue=SignalMACD

priceMACD=(macdValue+((1-alphaY)*prevEMA2)-((1-alphaX)*prevEMA1))/(alphaX-alphaY)

pricerounded=round(priceMACD)
drawtext("ZMACD crossing:#pricerounded#",barindex,priceMACD+2,SansSerif,Bold,10)
DRAWSEGMENT(barindex-10,priceMACD,barindex,priceMACD) coloured(0,0,0)

return
```

Thanks for sharing the code but it is not possible to draw to the right of the current barindex with PRT unfortunately.

It’s what I thought thx for confirming Vonasi

You can’t draw objects in the future, but you can add blank space in a text string:
```
drawtext("                           *",barindex,priceMACD,SansSerif,Bold,10)
```

Thank you all for sharing this code.

I have the segment in the graphic, but cannot see the price tag on the scale on the right, even if marked in the indicator parameters.

Is there anything to modify please ?

Change the last line with:
```
RETURN priceMACD
```

Hi dear,

Thank’s for sharing !

I’m not using PRT but MT4 instead… I’m beginner with MQL4 langage but I’ve tried to code it, it gives me something but the line isn’t really smoothed lol.

So I don’t know if it’s normal or not…

I joined a screenshot of my result (it gives me the pink line).

And following my MQL4, maybe somebody knows this langage and could help me to analyze it :

double fastMultiplier = (2.0 / (MACD_fastAvg + 1.0) );
double slowMultiplier = (2.0 / (MACD_slowAvg + 1.0) );
double signalMultiplier = (2.0 / (MACD_sigAvg + 1.0) );

//Print(“Fast Multiplier [” + fastMultiplier + “]”);
//Print(“Slow Multiplier [” + slowMultiplier + “]”);
//Print(“Signal Multiplier [” + signalMultiplier + “]”);

double prevEMAShort = 0.0;
double prevEMALong = 0.0;
double prevEMASignal = 0.0;

double priceMACD = 0.0;

if(i==0)
{

prevEMAShort = SimpleMA(i,MACD_fastAvg,close);
prevEMALong = SimpleMA(i,MACD_slowAvg,close);
prevEMASignal = SimpleMA(i,MACD_sigAvg,close);

} else {

prevEMAShort = ExtZeroLagShortDevBuffer[i-1];
prevEMALong = ExtZeroLagLongDevBuffer[i-1];
prevEMASignal = ExtZeroLagSignalDevBuffer[i-1];

}

double EMAShort1 = (close[i] – prevEMAShort) * fastMultiplier + prevEMAShort;
double EMAShort2 = (EMAShort1 – prevEMAShort) * fastMultiplier + prevEMAShort;
double DifferenceShort = EMAShort1 – EMAShort2;
double ZeroLagShort = EMAShort1 + DifferenceShort;
ExtZeroLagShortDevBuffer[i] = ZeroLagShort;

double EMALong1 = (close[i] – prevEMALong) * slowMultiplier + prevEMALong;
double EMALong2 = (EMALong1 – prevEMALong) * slowMultiplier + prevEMALong;
double DifferenceLong = EMALong1 – EMALong2;
double ZeroLagLong = EMALong1 + DifferenceLong;
ExtZeroLagLongDevBuffer[i] = ZeroLagLong;

double ZeroLagMACD = ZeroLagShort – ZeroLagLong;

double Signal1 = (ZeroLagMACD – prevEMASignal) * signalMultiplier + prevEMASignal;
double Signal2 = (Signal1 – prevEMASignal) * signalMultiplier + prevEMASignal;
double DifferenceSignal = Signal1 – Signal2;
double SignalMACD = Signal1 + DifferenceSignal;
ExtZeroLagSignalDevBuffer[i] = SignalMACD;

double macdValue = SignalMACD;
priceMACD = (macdValue+((1-slowMultiplier)*prevEMALong)-((1-fastMultiplier)*prevEMAShort))/(fastMultiplier-slowMultiplier);

ExtReverseZeroLagMacdBuffer[i]=NormalizeDouble(priceMACD, InpDecimalAccurate);

Hello NicoMich, sorry but you can’t come on a PRT forum and expects someone is going to help you with MT4…

~~Bonjour,~~

~~Peux-t-on avoir ce même type de reverse lorsque la ligne du MACD ZR uniquement (non pas la ligne de signal) devient croissante ou décroissante ?~~

~~Merci d’avance.~~

Hello,

Can we have this same type of reverse when the MACD ZR line only (not the signal line) becomes increasing or decreasing?

Thank you in advance.

Hello,
Thank you for this very interesting code. On the other hand, I would like to display the indicator in relation to the data of the previous candle in order to identify the zone to break for the MACD to turn around. Could you let me know how to go about it?
Thank you for your help
