DATFRA - Mt4 EA Builder & Walk Forward Analyser

Darwin,

There are no error messages, etc. it just didn't continue when I loaded it. Double clicked on DATFRA app in the DATFRA folder and then the first time it asked to install GNU which I did, and then the second time it asked if I would like to get the most recent updated DATFRA which I got. Then the third load, it just loaded the GNU and then nothing. No messages, no pop up, no terminal, nothing.... :-(

Thanks in advance.

Did you unpack DATFRA? Some ppl try to start it right out of the rar.
When you did install gnuplot and start DATFRA, sometimes it takes a bit until the program starts, as my hoster screws around from time to time.

How you mean "it just loaded the GNU"?

-Darwin

Yes I unpacked it. Maybe I will try again with a fresh download.

When I start DATFRA it runs GNU. And that's it. DATFRA didn't show up.

You mean gnuplot, i guess. So, there is that black cmd.exe box popping up with gnuplot in it and thats all?
Did you install the gnuplot i linked to from the manual?

-Darwin

Yes, because I am not a very technical guy, I followed word for word.


Latest Edit: Darwin, I got it to work now. Thanks. I just dumped the old download and downloaded a fresh DATFRA and went through the process all over again. Thanks.

Good to hear it is now running And thanks for the feedback!

-Darwin

Great and one-of-a-kind piece of software!
These things are what makes FF a great place with nice people who believe that sharing makes you get a lot back!

I hope i can give my humble hand to spot out bugs or "possible" improvements.
Thank you !

Thank you for the nice feedback

And here, finally, a new update!

22.9.2014 - Full Builder released!

The flexible builder for professional EA development is now part of DATFRA (not only the simple one).

However, I currently lack the time to write a proper tutorial for this, so that might take some time.. Until then, have fun with experimenting!

22.9.2014 - WFA: PSA Filters applyable

You can now apply PSA filters to your WFA, in order to check if the true characteristics of a trading system is also existing in a WFA, which is a highly reduced subset of a PSA after all

22.9.2014 - PSA: Filters now save-able

You can finally save and load filters that you create using PSA

22.9.2014 - Builder: Minimum Fitness Now changeable

You can now give the strategy-builder minimum fitness values, and it will ignore every system that fails to break that thresholds!

22.9.2014 - WFA display: closeable during loading

Something that bothered me for some time: When you open a WFA result now, and decide to close it before it is totally loaded, loading is now canceled

22.9.2014 - Papertrader: Autoscroll

The papertrader now has an autoscroll option, which can display a new bar every X seconds without user actions!

22.9.2014 - Parameterspace: Better parsing & bool values

DATFRA can now also work with bool variables in an EA, and it wont parse out-commented parameters anymore!

22.9.2014 - Built Systems: Finally readable variables

Something I wanted to do for a long time: When the builder now creates systems, the names of the variables used in the created code, are finally readable. So when you make changes, you know what you do

22.9.2014 - Built Systems: better preview!

In order to sort out bad built systems, DATFRA will now display every tested market in the "preview images"!

22.9.2014 - Updated Building Templates

The EA templates, that DATFRA uses for strategy building and that can be used as EA-dev-quickstart have been updated

-Darwin

Hi Darwin-FX, firstly thanks for sharing this product for free, very kind of you. I am about to install and try it. However, when I scanned the DATFRA_FEE.exe file (like I always do all exe files before I install on my PC), the anti-virus program I used picked up the following virus - HW64.Paked.13F8. Any comments?

I guess "Paked" means that it detects the encryption of the exe using "software-passport armadillo", which is basically used for the licence protection

But be asured that there is no virus in there, and if that would have been my intention, your anti-virus program would not have detected anything

-Darwin

Okay, thanks for the assurance.

Also, writing such a huuuge framework would be a bit of an overkill to spread a virus haha

Anyway, just wanted to say thanks for the feedback!

-Darwin

You are welcome

I’m having problems with installing and running DAFTRA. When I click to run it, the message comes back…” Cannot find gunplot.exe! Please download and install gnuplot from the just opened website.If you already did so, and it does not work, you might create ‘gnuplot_path.txt’ within the bin directory, with the path to gnuplot.exe in it.”
Can anyone please help? Just how might this be done. I am not a programmer etc. Thanks.I have tried the email, does not seem to work.

I did not get any email.

Did you install gnuplot as intended? If so, create a file "gnuplot_path.txt" in DATFRA\bin and put the path to the gnuplot.exe in there.

-Darwin

Darwin: Thanksa.
I did as instructed. But can you pls explain step by step on where how I can do that?/. Thanks

1. Search for gnuplot.exe

2. Copy its file location

3. Make gnuplot_path.txt to tell DATFRA where to find it

4. Some over-reachting malware-protection software prevent DATFRA from launching gnuplot.exe, for whatever reason. If it still does not work, try this on an other PC or try to disable your antivir/firewall/whatever in order to test if that is the problem





-Darwin

Darwin:
Thanks alot. Your instruction is clear. I will follow and feed back.

No problem, this is a common error anyway, so I now have something to point people to

-Darwin

Thanks. I have done that and have also installed and re-installed and now am onto the stage of 'Meta Trader'-> rebuild cluster. When I follow the instruction I got an error message as below. Please advice.
