Topic: EA Studio - News and updates

Hello Traders,

I'm starting this topic to post the current updates to EA Studio.

Re: EA Studio - News and updates

New Version of EA Studio is uploaded. It shows the trading times correctly by considering the users time zone.
Now you have the same deals time in the MT testing journal and in the EA Studio journal no matter of your local time zone.

Re: EA Studio - News and updates

EA Studio has Italian translation.
The app was translated by Diego Zancoli and Claudio Zanoni.

Re: EA Studio - News and updates

Great updates. I just subscribed to this, so I don't miss anymore announcements.

Re: EA Studio - News and updates

Added possibility to draw indicators as dots and as dashed lines in the main indicator chart.

Added "Donchian Channel" indicator. Please test it carefully.

Thanks

Re: EA Studio - News and updates

Hello Traders,

EA Studio has Spanish translation!

The translation is contributed by Juan David Corrales - professor at the Universidad Militar Nueva Granada in Colombia.

Re: EA Studio - News and updates

Balance Line Stability metric is added. It can work as a Sorting parameter in the Collection and as an Acceptance Criteria.

Re: EA Studio - News and updates

Hello Traders,

You can set now the shown "Backtest Output" metrics for the Editor, the Generator, the Collection...

You can find the new options in the left bottom part of the Settings page.

Re: EA Studio - News and updates

Hello Traders,

New version of EA Studio is uploaded.

The changes are mostly internal. I rewrote the way EA Studio shows the stats parameters and also added two new metrics:

Backtest Quality - it shows the backtest precision in % of bars. 100 is the best value. Lower values are only possible when you use both SL and TP. You can find out more info in that post: Backtest Quality

Stagnation in days - it shows ... the stagnation in days of course.

Both parameters are available as Acceptance Criteria.

Re: EA Studio - News and updates

Really, really great updates, by using stagnation in days, I don't need to update the stagnation value everytime the bar number is increasing.

And I just realized how convenient the backtest metric output is, I don't need to click each strategy to see other stats.

Thanks again Popov.

What seems too high and risky to the majority generally goes higher and what seems low and cheap generally goes lower

Re: EA Studio - News and updates

Added:
- Average position length in bars
- Bars in trade
- Bars in trade %

The new params are available also as Acceptance Criteria. These conditions may help to prevent strategies that trades on "random" events or that explore long trends.

Here is a screenshot of possible Acceptance Criteria usage:

The new params set to be shown in the Backtest output.

Please post ideas, feedback and bug reports.

Re: EA Studio - News and updates

Hi,
i have an idea for now we can set up to 5 values shown on right at eastudio. Why not use also a small button or something mouseover. When i go with mouse on Details Buttons for example than show all other informations also as a tooltip.

Re: EA Studio - News and updates

Ι think a good idea is to have different Acceptance Criteria for generator settings and Optimization settings when they used.
The speed can be better etc.

ps  I cannot see the new params set to be shown in the Backtest output.
      I still see Max Drawdown
                      Return / Drawdown
                      Count of trades

Re: EA Studio - News and updates

Please read above.

You can set your favorite params in the Settings page.

You are right. I also think for something like that, but I want to keep the UI as smooth and simple as possible.

EA Studio is created with plain JavaScript and Bootstrap v3 and it is relatively easy to be modified. Any design ideas and improvements are welcome smile !

Re: EA Studio - News and updates

New Version of EA Studio is uploaded.

You must reload EA Studio because the page files are relocated on the server and the navigation bar must be updated.

Noticeable changes:

- The first button in the nav bar is named 'Home" now. It was previously "EA Studio". This change allows us to make screenshots and videos that will not contradict with the partners brands.
- The language menu is moved to the home page. This frees space on the navigation bar. It is useful for languages with longer words like Bulgarian and Russian.
- The Data Import and Data Horizon pages have own button on the nav bar. It makes it possible to reach the Data Import page with one click now.

I hope you will find the new design more concise. It also gives us opportunity to further improve the Data import workflow and the user experience.

Re: EA Studio - News and updates

Added a new metric - "R - squared". It shows how linear is the balance line. It has values between 0 and 100, where the higher, the better

You can use it for a search target in the Generator, the Reactor and the Optimizer.
It is also available as an Acceptance Criteria and the Collection sorting and filtering.

If you want, you can make it visible on the Backtest output from Tools - Settings.

Here is a possible usage as filtering. The shown strategies are produced by the Reactor with turned Optimization on and set to optimize for best R- squared.

Re: EA Studio - News and updates

New version uploaded.

- Periods of Stochastic and Stochastic Signal indicators can be up to 200.
- Temporary enabled data import up to 500 000 bars.  (you have to increase the limit in the Data Horizon first). We will see how it works and will decide how to make it permanently. Most probably the setting will be up to 100 000 bars for trial users and up to 500 000 bars fro licensed users.
- I started  a complete rework of the backend of the user interface. There are no visible changes, but it must make the parameters of update up to 200 times faster and smoother. Now about 25% of the screens are updated. The complete work will take a month.

Please report all issues.

Re: EA Studio - News and updates

Amazing Mr. Popov, EA Studio is quickly gaining super-power this year with these changes and at this rate, wow :-) Thanks again for the good work and I am very happy that I can now load more data too! 500.000 bars allows me to load all my 32 years of M30 data (~400.000 bars), nice. I´d still say it would be great if you´d make all the parameters configurable and remove the bars limitation for the real "freaks" here, because I´d really also like to try to build on 32 years of M15 data, but those are 800.000 bars :-) It wouldn´t be a problem with Firefox as it has no memory limit per tab like Chrome has (4GB). But as far as I remember, you´ve anyway planned to make all the settings changeable in the backend in the longer run.

Thank you again!!

Re: EA Studio - News and updates

I'm amazed to see how quick you deal with bug fixes and all of the updates.

EA Studio is a masterpiece.

Well done Popov!

Re: EA Studio - News and updates

Some fixes made to ensure correct work in Internet Explorer 9+. We highly recommend to use some modern browser in that order:

1. Google Chrome,
2. Mozilla Firefox,
3. Microsoft Edge

Anyway, if you are forced to use IE (for example on a VPN or on a business machine, where you cannot install software) EA Studio must work.

Re: EA Studio - News and updates

1. Fixed a bug with Trading Session - EA Studio backtest allows closing out of the allowed hours. (Thanks to Geektrader and Roughey)

2. Language phrase updated. (the new phrases needs translation)
