Can somebody tell me how to get those indicators to work? I put them in my experts folder but when I try to use them they simply do not show on my charts.. Help would be appreciated.
place them in your experts/indicators folder then restart metatrader. they should show on your list then. These are indicators and not expert advisors.

Here you go. It's not just the looks, the MT4 default MACD indicator actually calculates it differently/incorrectly.
KGB, you are correct. I hadn't noticed this before. Thanks for pointing it out.

Here is what appears to be happening (differences in bold typeface):

Traditional MACD:
MACD = EMA(12,close) – EMA(26,close) [plotted as a line]
Signal = EMA(9,MACD) [plotted as a line]
Histogram = MACD – Signal [plotted as a histogram]

MT4's MACD:
MACD = EMA(12,close) – EMA(26,close) [plotted as a histogram]
Signal = SMA(9,MACD) [plotted as a line]

I've checked a few internet TA resources (list here: http://www.forexfactory.com/showthread.php?p=1810688) and they all seem to agree that the signal line should be an EMA of the MACD line. Metaquotes is the one exception, using SMA.

Whoa, guys...this just make me start to wonder... if the other MT's indicator, such as Moving Averages and so on, are also incorrect. Has anybody ever check them out?

There isn't any "not correct" in the code of an indicator unless you coded it and it's not doing what you want. Indicators are developed to do different things. Even most Moving Average indicators allow you to choose the type of MA you want... Simple, Exponential, etc... calculate on Open price, Close price, High/Low, etc. If you're not happy with how an indicator works, then find one that makes you happy... there are thousands available. Or, you can do what I did and learn to code MQL4 and develop your own.

I think the MA calculations are correct...I did calculate the simple, exponential, etc. manually and it looked correct to me.

Right. The default MACD is not showing you the correct histogram. Good luck in your trading!
Trader KGB, do you know what you talking about?
do you know difference between Macd and OsMA at all?
you messing-up Appel's(macd) with oranges

as many people already told you: standard mt4 macd is absolutely correct, it presented as histo :

macd: ema fast - ema slow
osma: macd - signal ma (difference between macd and sig.ma)

sometimes osma might be called macd histo where macd line, signal line and osma histo presented in one indicator

mt4 macd signal line is sma instead of common (and original Gerald Appel's) ema; reason: 1) sma snoozing smoother (that what signal ma also intended to do - it bit slower as sig.ma but less bumpier); 2) just to be different (guys who made this soft (one of the best in the world) not a bunch of idiots - they know what they doing (better than some users), and can allow themself to be a bit different)

here's macd with variable settings - you can choose watewer ma mode, price lines, or histo you like

Why are we digging up a thread from 11 months ago? Hasn't this topic already been beaten to death at this point? WHO CARES, just use whatever you prefer!

The 'MACD True' indicator attached to TraderKGB's post #2 correctly follows Gerald Appel's original formula (see here, for example).

The calculation in MT4's factory-supplied MACD is different, for the reasons outlined in post #23.

For more info on MACD, see here.

The point is- incorrectness of using such terms itself –calling mt4 macd True or Untrue (false) correct or incorrect.

If we talking about macd in general - Appel's formula (ema-ema-ema) –only "The most popular formula for the "standard" MACD" (see here, for example) /post32.
If MT stated – they using org. Appel’s f-la – then it will be untrue or incorrect.

Otherwise – such faulty logic leads to calling settings - untrue or histo/lines drawstyles – false, and ends up with nonsense: who uses macd 5,34,5 – uses incorrect (untrue) macd…- absurd.

Can someone explain to me how to download and execute these indicators on a Mac iOS system. Everytime I download the indicator it saves as .txt.


Help would really be appreciated.

You will need to add some timed delay to the code, so close crossings will not alarm more than once.

There is no limitation.
If your other mt4 account is on another platform, you need to copy the indicator to its folder there too.

Its is more important that the indicators in a platform are consistent. It is not that important that an indicator is 100% correctly calculated. Indicators are after all a trigger, and should not be used as the sole input to a strategy. It can sometimes be an advantage to use a modified version of an indicator not to trade when all the others trade - or even skew the time in the platform 5 seconds may give you a better fill.
