MT4 Windows 8.1: why some indicators don't work anymore?

Hi,

Maybe something you guys also encountered ....
I have on indicator in MT4 ( a sort of special fibo system that I made ).
The indicator works perfectly well on my laptop windows 7 running FXOpen version 4.0 build 840
When I try to use it on my new laptop running Windows 8.1 then MT4 crashes...always !!

Whatever I do , when I call it MT4 crashes... I have try to compil the source code on new machine in case ..same pb.

That's a very strange issue as I don't see why a specific indi working well on windows 7 should not work well on windows 8.1.

Important to mention , in both cases I still use same FXopen version 1.0 build 840 .

Any ideas ?

Thanks

Try to run the program in compatibility mode for "Windows 7" or "XP SP3" and see if it works better

If you post up the code, I'm sure some of us would look through it to see what might be causing the issue. Otherwise we're shooting in the dark

Since you know how to code start doing by removing code parts and start debugging the part that causes the crash.

Start commenting all code lines and then uncomment it part by part to see when W8.1 starts to show problems. That way you will also detect the function or the loop or whatever code snippet causes the problem and this could even help others to deal with same issues.

Happy Trades
Focus only on what truly matters!

Thank you guys for your suggestions.
Sorry , I cannot share that code ( too much hard work there ).
I 'm probabbly going to isolate the pb in cutting my indi code in small blocks...
What make me really crazy is why MT4 code inside an indi makes MT4 crashing in windows 8.1
I really doesn't understand what could happen as I don't think interfer with Operating system.
Unless the graphical stuff ... as my indi draws hundered of lines... maybe the dell laptop with the GEFORCE processor is the killer...
I hate windows 8 ...

Good luck
Out of interest, is max bars on chart set the same on both terminals?
Any DLL calls?

Wait 20 days until Windows 10 is out.

Thank You

I think I find the pb...
my indi when it's relevant gives me a sound alert with a .wav file from sounds files. Of course , my indi cannot find the wav file because there is a new way to manage files in windows 8.1

still learning...

Just a thought does your new laptop run the full window 8.1 or windows 8.1 RT because if it is the RT version that could be the problem with your custom indicators or is your problem specific to one indicator only.
Trade what you see not what you hope

Fairly certain that RT can't install the desktop terminal, which means that there isn't anywhere to even try to add a custom indicator.
Not tried though, so could be wrong

I'm using 8.1 ..my problem is specific to one indicator . Many others indicators ( I made ) work well. maybe I found indirectly a "corner bug" in MT4..

I was wondering if someone knows why the way the files used by MT4 is different depending of windows 7 or 8.1 versions ?
for example, in windows 7, when I look inside FXopen ECN MT4 folder ( in program X86) I can see all the files. Then , If I click on files folder in MT4 I see the sames files , noone is missing....
In windows 8.1 , when I click on files folder in MT4 I can see some files only... the sounds file is missing. The pb is my indi is calling the sounds file.

With the new data structure, the easiest way to get to the correct folders is through the terminal:

Metaquotes completely overhauled the data structure last year which means you have 2 similar, but different, folders.

This folder is found where you installed MetaTrader. It is where you should add the sound files:

This folder is well hidden away. The best way to access it is using File > Open Data Folder. This is where you should add all your custom indicators, scripts, EAs etc:

To avoid these sort of issues, I don't install MetaTrader in Program Files. I install it somewhere else and then I always run the terminal in portable mode. This puts everything back where it used to be like the old days (must be a dinosaur, but I liked it that way!).

However, I must apologise. My previous post shows you accessing the sounds folder through File > Open Data Folder. That only appears if you run in portable mode. Otherwise, sounds is found where you installed MetaTrader.

Perhaps try installing MetaTrader again, but not in Program Files? Did you check max bars on chart between the 2 installations?

Thank you so much for your support and your time..
I think I'm going to make a pause during the Weekend.. as I have just discovered this morning I can also crash MT4 on windows 7 if I apply it on NZDCAD... yep only on that pair ! I never noticed this as I never trade this pair.. it's works well on USDCHF , USD, GBP/USD... etc
hahaha..what a mess. It could be nice to have a sort of MT4 program execution tracer so that we see where the program fails..
