using sounds in MT4

Hi,
I'm new to this Site, and new to trading. I use Metatrader 4 & spread bet with Capital spreads - London.
I also have poor eyesight, and its getting worse - age I'm afraid.
I would like help on the following -
Due to my eyesight I need Wav. alerts on all my indicators. Most already have them, but there is one refinement that would make life so much better for me... and its this.
All my indicators have a program line like this: PlaySound("thunder_1.Wav.") or something similar.
What I would really like to do is add another section/wav. to it, such as - PlaySound("ProfitTaken.Wav."). The "ProfitTaken" would be a spoken message ( I already have the recording)
The idea being that the first one will grab attention, and the second will explain why. Is this possible?
Thanks
Springer

If the second sound has to be played immediately after, you could consider merging both sounds in a single wav file.

If the first one is being used for several purposes, you could just rename the merged wav to be played for that particular indicator.

Then, just open the indicator with the Meta Editor, change the wav name to the new wav, and compile.

I've done some work with text to speech before, and I think there might even be something already done for MetaTrader. If you could do something like...
PHP Code
textToSpeech("Profit taken at " + Bid);
and hear a fairly robotic voice speaking, would that be useful?

If so, once the house is quiet I'll take some time and dig into this a bit to see what I can find.

Springer,

Welcome to FF. This is an exceptional forum with many fine people. A great place to start your journey of becoming a trader.

Your suggestion of an attention getting sound and then more detailed supplied by a second .wav file is a good one. Seems like this should be straight forward like two consecutive PlaySound functions, “ PlaySound(alert1.wav); PlaySound(alert2.wav);” but this does not work. Apparently only the last function will play. Probably the first thing you tried. Concatenation, “PlaySound(alert1 + alert2);” does not work either. There may be a straight forward way to successfully play two PlaySound functions but I do not know how. They just seem to get in the way of each other.

I suggest that you might consider using your text-to-speech engine directly. Initially MT4 had a SpeechText function but it was removed a year ago. Codersguru wrote two modules to restore this capability. The advantage of using a speech function is that you can concatenate values. This allows you to form an audible alert that is as complex and detailed as you desire. Also you do not need to have prerecorded .wav files but can use them if you so desire. I have attached a zip file that contains detailed instructions, the two speech modules and some examples of two trendline alerts by Accrete that I modified to use speech. Hopefully you will find this useful.

I really do appreciate the fast, and informative replies from you guys - many forums appear to promise much, but non have produced such an 'avalanche' of help & assistance. I shall put everything to the sword and get back to you.
Thanks again.
Happy trading
(I am putting something together & will be testing it over the next four weeks. If it performs, I,ll thank you all by posting it)

I ran into some problems by combining the PlaySound function and the speech function. I have now removed PlaySound from my previous modifications. I also added all six major pairs to the indicators. The updated write-up, speech modules, and indicators are attached.

Hi Hapalkos,
Sorry for the delay in getting back to you - small family crisis!
The situation so far. I opened your zip file to my desk top... and there my computing skills end. Any help on what I do next would really be appreciated.
From looking at the MetaTrader files they appear to be just what I need.
Take care.

Well we need to get those files off your desktop and to the appropriate folders described in the write-up. The best way to get acquainted with MetaTrader is to go through the stickies at the top of this Forum. Lots of good information there. Spend some time with the tutorials written by Codersguru in the thread, "MT4 Programming Resources." It is the first post in the "MT Information" sticky. Soon you will be comfortable working with indicators and scripts.

A good way to learn is to take an indicator that you are interested in and modify it slightly (color, line type and thickness or whatever catches your interest). This will get you reading the code and seeing the results of changes you make. Be sure to reference the Dictionary in the MetaQuotes Editor. There is a lot of good documentation within this dictionary.

Hi Hapalkos
I have attached the indicator I'm interested in. The e-mail part I would like to retain. The alert is the one I would like to alter to voice. In the mean time I will follow your advice and keep you posted on my progress.
Thanks for the interest in my problem, I appreciate it.

I have modified the indicator with the speech function. I also did a second indicator with PlaySound. I have not yet recieved an activation signal from the original indicator or my modified version but I have them both on test.

Hopefully it will work as designed and be helpful to you.

Hi, There appears to be a problem with the indicator. I do not think it is anything you have done. I cannot get a signal from the original either.
I have them both on a one hour chart, but nothing happens. Possibly there is an error in the original program...?

If all else fails, is it possible to add an e-mail alert to 'TriggerLines' They do practically the same thing as as the Slope indicator.

Springer,

The email alerts appear to have been added on to the original indicator. Has it worked for you in the past? If not, maybe the logic to trigger the email is not correct.

Springer,

I have added the SendMail command to TriggerLines. I have not tested yet because I do not have MT4 email working on my machine correctly. I have never used the MT4 email function before but started setting it up earlier this evening. Unfortunately, I do not yet have the addressing correct. If you have MT4 email working then maybe you could test it out. If it works then we can proceed with customizing the indicator.

Hapalkos,

No, The e-mail has not worked. It was added to the original, and I found it while browsing another forum.
Do you think you are able to correct it?

Hello Tesla,
Besides MT4, I am also uning the RF2000 platform from realtimeforex. I find it quite helpful with their audio pricing. As the price moves it announces the last 2 digits of the bid and ask prices like - 95_98 ( For 1.2895 / 1.2898 ask/bid )
My question : How can we program that into MT4? If I have the code how to do it, I will do the wav myself.

Thank you and to anyone else who could help.

Highway.
P.S The demo platform from realtimeforex is free if you want to see what I mean.

It should be in the ".../experts" folder, not ".../experts/libraries"

It's hard for someone else to say what an ex4 file does, because it's already compiled. That means we can't open it up and read the source code to see what it's programmed to do. Your best bet is to find some kind of documentation for it.

If I recall, you just use MetaTrader for charting/alerting and do your trading with a SpreadBetting company. If this isn't the case and you use MetaTrader with real money, please please PLEASE test any kind of EA code that you receive from a third person or download from the net. It can be pretty easy for someone to make a simple coding error that causes big problems.
