check out my code.

Take out these lines and it could be indicator.

"extern int FastEMA=3;
extern int SlowEMA=34;
extern int SlowEMA2=89;
extern int SlowEMA3=144;"
The future depends on what we do in the present.

I think I have set everything up correctly but I keep getting the error message

Mail:550 Sender address is missing a domain - even though I have a full email address with no mistakes.

Any Idea what to do or what that means? I am using my full ISP email as suggested.

Also must the To: email be a different email? I have tried many combinations but met with no successs.

Any advice welcome.

Thanks for all the help.

BTW I route the email to my mobile which rings when certain prices are hit so now I need much less screen time!

I am just manually setting price levels at which I know my setups will be near their trigger point. At this stage I am not using an EA but I might look into it soon.

I have an i-mode mobile which comes with an email address. I simply put that into the to: section of email alerts and it rings when a new message is sent.I have it set to a special ring tone. I think It caosts about 2.2 cents per email to receive. It is on the Telstra network and is somewhere below G3 and Blackberry technology but still OK for small emails with no attachments.

I hope this explains everything.

Somebody can help me with this please ?

I have one problem, which is that the ema's are not updated ..
I mean, when I start the script, the value work fine, but then into the loop the value stays always the same ?!
and the loop is going through becaquse I have a counter telling me the loop is active.
any suggestion ?

OK, after a long search for a MT4 indicator that would give me the following:

Arrows on the chart,
Sound File,
Send Email

upon a cross.

i've mirrored it as my site so i'll always have it:

MA Crossover Alert

hI Thom,

As I see you are a good mt4 developer, better then me for sure, can you help me with this please ?
I dont understand what is wrong.
basically I have a loop (with the for... etc) and within the loop I have the constant check of the 2 emas I decided.
this are the the lines into the loop :


EMA8=iMA(NULL,1,8,0,MODE_EMA,PRICE_CLOSE,1);
EMA9=iMA(NULL,1,12,0,MODE_EMA,PRICE_CLOSE,1);

So , what happens is this:

the first time i print the two EMA8, AND EMA9 variable on the screen (as a comment) they look fine, but then they remain all the time the same...they dont change anymore, even if the ema lines in the graph change value meantime.
Im sure the loop is working cause I have a counter showing is keeping goig, but this to variables are not updated...
Do you have any idea ?
this is driving me crazy, cause I need to alert me when they cross eachother.
Thanks!
Chris

Hi Trucco,

Try creating it again.

I know that sounds like a bit of work, but you'd be surprised how often the exact same code will work once you re-start. And I mean a whole new script, don't just delete all the lines and re-type (though that might work too. )

I'm positive the MT4 compiler has bugs.
Just yesterday one of my indicator lines refused to work after modifying it. Even in the data window the value stayed empty. Even after giving it a hard coded fixed value!!!

Good luck mate.

EMA8=iMA(NULL,1,8,0,MODE_EMA,PRICE_CLOSE,1);

Oh , I take that back...

...in your case anyway!

EMA8=iMA(NULL,1,8,0,MODE_EMA,PRICE_CLOSE,1);
EMA9=iMA(NULL,1,12,0,MODE_EMA,PRICE_CLOSE,1);

the "1" (after PRICE_CLOSE) needs to be indexed. At the moment it's using the same bar to calculate every other bar's EMA value. :

i.e. In a "for" loop (say "for(i=10;blah;blah)" you'd use the "i" instead of the "1". So that it indexes to the bar you're currently calculating.

Hi Bundytrader, your kind words should be directed to the developer of the MA i "found". While i doodle w/MT4 indicators, there are many on this forum that could have all my MT4i knowledge in their pinky finger ; - )

I think mine's about an index finger's worth now. :

Not being able to take the compiler for granted makes it a little harder.

Thanks to all guys.
I tryed all as suggested, but nothing works

Bundyraider, but If i put the 'i' as last parameter, I see that the 2 emas values make a kind of continus loop of 12 pips.

For instance, it starts with 1,8405 - 1,8206 ....1.8215 and restarts again, 1,8205 etc etc ...same as before .
Is this normal ?
I wanto to automatize this indicators I use and try in mt4 with simulation to let it run automatically for a month, and see what happens...but the basic things are not working !

Any suggestion appreciated

oh boy oh boy

normally i'm too lazy to write a posting, but i see that there is no one that can help you, so i will

The problem is, that you do not know how the EAs in metatrader gets called and how the price data is updated.

It works like this:
Every time there is an incoming quote change in the chart the EA is attached to, the internal varibles like open, high, low, close, time, volume etc. are updated and the Start() function gets called. Theese variables do not change while code is running inside the Start() function. And that is your problem. You are keeping youre code in a loop and every time you read the value of close you get the same value.
The solution is to redesign your code - do not use a loop and let the Start() get called with fresh data.

You should also take a look on the MarketInfo() function... it will not help you in this case, but it is good to know that there is such thing.

Hi Robik, Im afraid is still not working. I dont know why.
the script is very simple. I have put a counter, so i know how many times the start() function is called, unless, everytime the start() is called all the variables are reset.

So the result of the script is that the counter doesn't increase, like the start() is not called anymore, and also the 2 emas stay always the same.
This is the code.

( if i restart manually the script on the graph it works, only the first call)
I compiled it as a program, maybe should be an indicator ?
Thanks very much if you can help me with this

//---


double diff,diff2;
int k=1, n=2,t=1,m,counter=0,counter1=0,lungo,corto,Z;

int init()
{


return(0);
}

int start()
{



t++;

double EMA4=iMA(NULL,1,8,0,MODE_EMA,PRICE_CLOSE,1);
double EMA5=iMA(NULL,1,12,0,MODE_EMA,PRICE_CLOSE,1);


diff = EMA4 - EMA5;
diff2 = EMA5 - EMA4;

hmm i have no idea what your problem is. You saved this as mq4 file in your Experts folder and compiled it? then you attached this EA to a chart and your metatrader has enabled execution of expert advisors?
it worked for me.
