Hello Helee, thank you very much for the bug report.

Do you have skype? It would make fixing that bug a lot easier
And can you, after this crash happened, open "debug_log_utils.txt" (in the DATFRA-M main directory) and paste me the last 10 lines?

Thanks in advance,
-Darwin

Don't know if my email arrived. But no matter. I now have your excellent software running on Linux using Wine.

Couple of points to note:

  1. had to change the path in price history storage to read "C:\DATFRA-M\bin\..\ROOT_DIRECTORY\intern\metatrader-cluster\MT_0\history\AlpariUK-Spread-Betting\" before history was recognised
  2. DATFRA is recognising the forex history, but not the indices history; the S&P500 is called US500.Z1.hst (Z5, Z15,Z30...).

Thanks.

Hello Darwin, also, the "auto-execute" function in the paper-trading section has some issues, once played works, but if put in pause and the re-played it won't work anymore and needs to reboot datfra-m. Hope it's helpful thank you regards
Did check and it seems to work for me. Can you elaborate on what you did to "break" it?
I started the "automated scrolling", then stoped it, then started it again, and it still works. After stopping again I tried the manual "show next bar", and it also works.

Thanks already for the help!

Hey, yes it arrived, thanks
Yes, only forex is supported at the moment, and I will look into the history problem!

Thanks for the feedback,

UPDATE

* Fixed a bug causing the paper trader to do nothing
* Fixed a bug causing some systems only to trade one direction
* Improved builder default settings
* Fixed a bug that did prevent the history from beeing recognized.

PS: To update, download the new .exe DATFRA-M will guide you to, and then replace the old .exe with the new one, thats it!

Hello Thx, thanks for the nice feedback Good to hear you like it!


BUG-REPORT, ATTENTION
Sometimes the history is not correctly moved. If you do not see any history recognized, go to DATFRA-M\Root_directory\intern\metatrader_cluster\mt_0\history and move the contents of the folder that has the history data (mostly the largest one) to defaut

I will fix this bug on sunday or monday, but until then i dont have time for that :\

There will be a new update today or tomorrow, with new builder-functions (bollinger band), an updated EA template (should improve generated systems as it prevents them from taking "mini trades" that only go for 1 candle or so), an option to add custom indicators for papertrading, a fix for windowsXP and some minor changes.

However, due to a few changes, I had to reset the cloud, so new users will not get any systems out of the cloud for now. But dont worry, soon it will be filled again

And then, perhaps next week, I will release DATFRA-M (beyond this small soft launch)

Stay tuned,
-Darwin

UPDATE

 

  1. 05.11.2014 ;; I did reset the cloud (sorry guys, but soon it will be full again!) and improved the builder-EA-template
  2. 05.11.2014 ;; Added Bollinger Bands to the builder
  3. 05.11.2014 ;; Added an option to add custom indicators to the papertrader
  4. 05.11.2014 ;; Might have fixed a bug regarding windows XP (need feedback, I dont have XP here..)

-Darwin

PS: The alpha (that is associated with thevery small soft launch in this thread) might soon be over, so I can finally go more public with DATFRA-M

Just wanted to let you guys know that I am currently reworking the builder (the new systems will be more.. "sound"), fixed a few bugs (for example the papertrader always started from 2005..), and I have added a first version of the AI advisor!

The AI advisor can analyse your trades in the papertrader and make suggestions like "If you would only have traded long when price was above movingAverage(50), you would have increased your profit factor to 2.4" an stuff alike

Stay tuned, I plan to release it on monday.

Hi,
I wanted to say BIG thanks for this awesome tool!
Last week I was doing walk forward analysis manually with Mt4 for my system, it took about 3 days for one full test on one pair... it was so big frustration to do that, it felt like huge time wasting Not talking about how unhappy I felt after I got unreliable negative results... So happy that I found this thread! Your WFA tool will save me tons of precious time.

At the time trying to understand PSA and how to use it properly. It seems very powerful tool, still need to digest info and try this analysis on my systems. Hope we can talk more about what to look for in PSA results for reliable robust systems and how it can help to develop them.

Thank you again Darwin-FX, and have a nice day

Thank you for the feedback If you have questions regarding PSA, you might just ask me.

DATFRA-M MAJOR UPDATE

1. Heavily improved the builder. The generated systems are now a lot more profitable and sound
2. Added AI-Advisor. It is able to monitor your papertrading sessions and suggest improvements to your trading style! (Do a new papertrade session with at least 20 trades, save it and then open the result. You will then see a new tab "AI advisor". Have fun!)

I also fixed the bug that caused the papertrader to always start from 2005-2013 instead of the correct date.

I did clean the cloud due to the builder update, so at this point in time, only a few eurusd systems are in it. But it will be full again soon

Awesome Darwin! Sounds like a great update. I have been running the builder pretty much non-stop since it was released and i cant wait to try this new, improved version!

The main difference (additional to many small changes and improvements) is that the new builder opens up more then one trade per system. This brings the benefit to evaluate a trading system in a better way, because if the "first trade" of a system was good by chance, but the overall rule was not good, the old builder would have seen a system "good" while the new version is not fooled by chance or "startup point dependency"

Additionally, the new version, due to opening more then 1 trade, makes a lot more profit and smoothes out winnings
