Do-it-yourself alert builder kit

Hi,

Thanks for your kind words.

Re your EA, all I can suggest is that you post a detailed specification on the Platform Tech forum, and maybe one of the programmers who contribute at FF will look at it for you.

Sorry I can't be of more help.

David

Thanks.

Do you know why the indicator wont load into MetaEditor?

You cannot edit the compiled (executable) copy of the indicator. You need the source code.

thank you.

Hanover, hopefully a simple request from a fellow Kiwi Semi-Retiree(Waitarere Beach, Levin).

I desire a simple audible alert to support the visual window alert in your early TDI Alerts.mq4 indicator.

I have searched everywhere?? and tried many TDI versions but can't find anything suitable available with the audible alert feature.

Please, can you help me here? Will your DIY kit do this job?

Many thanks and kind regards

Larney

I have coded... (Hey, sounds pretty impressive dun' it?) ... a "0-line alert signal" into the standard TVI indicator, thanks to Hanover's instruction sheet here. That I am able to do this is definitely proof that the thread is effective given my understanding of computer code: Success on the 2nd try (attempt to compile)! And thanks for including the extern. variable "AlertCandle", Hanover, it's nice to have instructions that are carefully thought out. This feature should be in every Alert indicator.

Correction from a few Hours Later:

Now, there are a few things still to do to this indicator before posting it in my TVI thread Optimizing the Tick Volume Indicator mostly amounting to changing explanatory strings (assuming I have the proper nomenclature) so a person using the thing knows what his entries in the the indicator's dialoge box are supposed to result in, adjustment-wise. Also, It still says "NonLag MACD cross UP" when the box appears, oops. BUT IT WORKS - and at least it's possible to differentiate it from the other TVI in the setup.

Hey Brucewhain, good effort and thanks for your trouble...

Unfortunately you have the wrong indicator (TVI). I should have included the TDI Alerts.mq4 indicator I wanted the sound alert added to, I'm sorry.

Here it is - could you please extend your much appreciated help to adding an audible .wav alert to the conditions I have set the attached mq4 to go off when the chart display window alert is triggered?

I really thank you for this help.

Cheers
Larney

Greetings Brucewhain - It has just occurred to me that your post wasn't in reply to my request to Hanover for sound alert - whoops!!

Sorry to sidetrack you - your post seemed like an answer to my prayers from programmers heaven - never mind, hopefully Hanover will be able to help.

Cheers
Larney

Well, no. (as you can see from the revision of the above post) And you take your life in your hands if you ask me to do anything that has to do with computer code, 'cause I don't know what the stuff means.

Nonetheless, went looking for the indicator you want modified and couldn't find anything by Hanover. Usually a google search will get access to most of the available versions of indicators. (You might have to sign up for Forex TSD - a site with a lot of indicators - in order to download.)

Did find one indicator called TDI-With Alerts (attached below) which might work for you. It was posted in code form, so had to copy it to my meta-editor, and it compiled ok.

The code has a great deal of explanation in it (or above it) which you might want to read, and you can do that after downloading (or copying: Not sure of the nomenclature here.) the .exe file (attached below) to you MetaTrader platform, by saving it to: "Your Broker's Version of MT4Expertsindicators". That is, click "save as" on internet explorer or other browser, then browse you computer & find the MetaTrader folder. Inside will be the "experts" folder, and inside that, "indicators". Save it in the indicators folder.

Then close down the MetaTrader platform if it happens to be open, in order to get the file in an operational state. (Sure there's some explanation why this is necessary.)

Once you open MetaTrader again you should be able to find the file under "Custom Indicators" in the Navigator, which should be on the left. If it's hidden, go to the "View" menu-item (upper left) click on it, and then click "Navigator" in the resulting dropdown menu. (There is a keyboard shortcut which Hanover usually prescribes for purposes of summoning up the Navagator, and you can find these shortcuts and lots of info on MT4, i.e. MetaTrader, by clicking on the "Help" menu-item.)

In order to read the coder's explanation located in the code, right-click on the indicator (Hanover has a keyboard shortcut that he usually prescribes at this point but it's only one additional click this way.) then, in the resulting menu, click "Modify".

You should then be able to read the coder's explanation of the indicator to see if you want to use it. Just be careful not to modify the file while it's open in meta-editor. (You would have to save it - or compile it, which is somehow different - to save any modifications you might accidentally make, so that's not likely.)

Bruce

P.S. that's ok ginal, hope this helps.

I've got the MQL file for this indicator. I've tried using Hanover's kit to add the email alert but just messed it up? I've read somewhere that its difficult because it draws objects?? Would anyone like to have a go?

I have tried too but I couldnt make it worked!

Ideally is to get an alert when the Supply or Demand zone starts drawing on the chart!!!!

Yes exactly, an alert when price hits support or resistance and a box is drawn. Without this i have no strategy.

Can anyone help with this? maybe Hanover? I know you must be busy but this is way beyond my scope.

Larney,

Not sure why you're not getting the sound coming through.

Provided that the ChartAlerts parameter is set to TRUE, the indy calls MT4's Alert() command, which should cause the standard MT4 Alert window to pop up, complete with the familiar chime sound.

If I understand you correctly, the window pops up, but without the chime?

If so, is it possible that you have sounds switched off as shown in the screenshot below? Or a fault with your computer speakers?

The indy generates the chime when I run it on my computer.

David

Complex indy, it's beyond my scope also. I tend to prefer working with my own code, which means I'd need to recode the indy from scratch...... but I don't know what it does, or how.

Yes, thank you Hanover, I found that the alert .wav was turned off.
The indicator now works just fine and is exactly what I want.

Many thanks

Kind regards

Larney

I thought you may have that problem. The indy basically draws potential supply and demand zones or S+R zones. Support is blue and Resistance is Maroon.

I think the code below draws the boxes:
I thought it would be as simple as adding the email function. Thanks for having a look, appreciate it.

if(BuferDn[i] > 0.0)
{
t1 = iTime(pair,tf,i);
t2 = Time[0];
if(use.narrow.bands) p2 = MathMax(iClose(pair,tf,i),iOpen(pair,tf,i));
else p2 = MathMin(iClose(pair,tf,i),iOpen(pair,tf,i));
p2 = MathMax(p2,MathMax(iLow(pair,tf,i-1),iLow(pair,tf,i+1)));


s = TAG+"UPAR"+tf+i;
ObjectCreate(s,OBJ_ARROW,0,0,0);
ObjectSet(s,OBJPROP_ARROWCODE,SYMBOL_RIGHTPRICE);
ObjectSet(s, OBJPROP_TIME1, t2);
ObjectSet(s, OBJPROP_PRICE1, p2);
ObjectSet(s,OBJPROP_COLOR,TopColor);
ObjectSet(s,OBJPROP_WIDTH,Price_Width);

s = TAG+"UPFILL"+tf+i;
ObjectCreate(s,OBJ_RECTANGLE,0,0,0,0,0);
ObjectSet(s,OBJPROP_TIME1,t1);
ObjectSet(s,OBJPROP_PRICE1,BuferDn[i]);
ObjectSet(s,OBJPROP_TIME2,t2);
ObjectSet(s,OBJPROP_PRICE2,p2);
ObjectSet(s,OBJPROP_COLOR,TopColor);
}

if(BuferUp[i] > 0.0)
{
t1 = iTime(pair,tf,i);
t2 = Time[0];
if(use.narrow.bands) p2 = MathMin(iClose(pair,tf,i),iOpen(pair,tf,i));
else p2 = MathMax(iClose(pair,tf,i),iOpen(pair,tf,i));
if(i>0) p2 = MathMin(p2,MathMin(iHigh(pair,tf,i+1),iHigh(pair,tf,i-1)));
s = TAG+"DNAR"+tf+i;
ObjectCreate(s,OBJ_ARROW,0,0,0);
ObjectSet(s,OBJPROP_ARROWCODE,SYMBOL_RIGHTPRICE);
ObjectSet(s, OBJPROP_TIME1, t2);
ObjectSet(s, OBJPROP_PRICE1, p2);
ObjectSet(s,OBJPROP_COLOR,BotColor);
ObjectSet(s,OBJPROP_WIDTH,Price_Width);

s = TAG+"DNFILL"+tf+i;
ObjectCreate(s,OBJ_RECTANGLE,0,0,0,0,0);
ObjectSet(s,OBJPROP_TIME1,t1);
ObjectSet(s,OBJPROP_PRICE1,p2);
ObjectSet(s,OBJPROP_TIME2,t2);
ObjectSet(s,OBJPROP_PRICE2,BuferUp[i]);
ObjectSet(s,OBJPROP_COLOR,BotColor);
}
}
}

It also gives a platform alert when price enters a demand or supply zone.

Really sorry guys. I gave you the old indicator when i should have given you the most recent one. It has the coding for the sound alert.

Hanover: do you think it will still need to be recoded?

Hi,

Your best bet might be to start a new thread. That would give your request greater visibility; perhaps one of the other programmers will help you. Or you could post in one of the "I code your indicators for free" threads.
