Can someone please write this?

I need a EMA/SMA crossover alert indicator.
Here are the parameters
Typical HLC/3
EMA 8
SMA 13

plus
13 SMA crossing 100 EMA

Any help would be greatly appreciated
Thanks

Hey mate,

I have just PM'd you - its unrelated to the above however - apologies... i just wanted to get your attention before i hit the sack.

Thanks...

in the dialog box it says faster and slower ema, but the slower ema is in the code changed into sma.

And, using 5 for price input makes it typical price.

Thanks but I was looking more for an alert style, something thats go ding-ding so when I am reading or wasting time here I won't miss a signal. MPP had one on my journal thread but there is too many bugs in it and it wont shut up even when there is no signal.
If someone who knows what they are doing maybe have a look at this and figure it out that would be great. Thanks.
Also if it could be made into one that works on all time frames, if I'm not asking for too much, which I know I am but it never hurts to ask.

To whom it may concern,
enclosed is the original indicator that was posted for an ema/sma cross over signal. i don't write code, but did change the colour settings, ema/sma numbers and the close to typical.

not sure if this would have affected the arrows. also because the timeframe can be set in the code it will show the ema/sma of that tf in any chart irrelevant of the tf.

this indicator is time settable so BWR, you will have to make your timeframe needs more clear - when you load the indicator you can change the timeframe and colour to suit your needs.

anyway hope this helps

Alright, so in my limited abilities I have gone after this challenge. The main trick was getting the alert to only go off once per bar. Thus far I have a copy which will work on the 1hr or less time frame. I'm working on one for either 4hr and up, or universal. But before I do that, I think a drink is in order before I slam my head against the wall trying to figure this out.

Some quick notes:

-You can now define the period of the MA. So MA1Per is MA1 period in bars, MA2Per is MA2 period in bars.

- I have broken it down from purely "SMA" and "EMA". MA1Style and MA2Style are defined as follows:
0 = SMA
1 = EMA
2 = Smoothed Moving Average
3 = Linear Weighted Moving Average

-I changed the way you can calculate the MA's as well. MA1Calc and MA2Calc are defined as follows:
0 = Close price
1 = Open price
2 = High price
3 = Low price
4 = Median price (High+Low/2)
5 = Typical price (High+Low+Close)/3
6 = Weighted price (High+Low+Close+Close)/4

- AlertMinute is when the alert will go off each time it hits the value entered per hour.
00 = start of the hour
15 = fifteenth minute of the hour, etc

-Delay is the size of the window, in seconds, you want to give the indicator to send an alert your way. If you set it to "15" it will only try and send an alert in the first fifteen seconds of the minute on which the alarm is set to go off, etc.

I know this isn't exactly foolproof and thus far only works on the 1hr chart (or lesser time frames if you set up multiple charts with multiple alert minutes). However, it's a start, and it's also the start of my evening so I must go now and habitate my bar stool. According to the spellchecker I have in Firefox habitate isn't a word, but who cares, we all know what I mean. Hopefully someone else who isn't a fourth grader in programming abilities will come along and help us out. Otherwise, I'll keep working on it, but don't expect sudden results.

just added the new bar function so your alerts dont go wacky. (multiple alerts ...now its just 1 per bar)
Managing mtf at once on metatrader uses a lot of resources when using
alerts easier if ea.
may want to copy over into bwr1h.mq4 alert.
Just add newbar script at end alert file and then
add if (NewBar()) in front of alert.


if (NewBar())Alert("SMA-EMA CrossOver Going for a SELL Trend Sesion ",SMACurrent," Price ",Close[1]," for ", Symbol(),"-",Period());
PlaySound("alert.wav");
if (Email)
{
if (NewBar())SendMail("SMA-EMA CrossOver", "SMA-EMA CrossOver Going for a SELL Trend Sesion "+DoubleToStr(SMACurrent, digits)+" Price "+DoubleToStr(Close[1], digits)+" for "+Symbol()+"-"+Period());
}
}
}
//----
return(0);
}
//+------------------------------------------------------------------+

bool NewBar()
{
static datetime dt = 0;
if (dt != Time[0])
{
dt = Time[0]; Sleep(100); // wait for tick
return(true);
}
return(false);
}

Updated the code with Weazel's most gracious help. Now we have a fully customizable MA crossover indicator that doesn't go off thirty times a minute.

Quick note: the dashed lines are the current MAs and the solid lines are the previous bar MA's.

Thanks so much for all of your help, Its still going off randomly sometimes but I can deal with it.
