Re: EA Studio - News and updates

> but I still got strategies with indicator periods below the "min indicator period"

Actually, the purpose of this option is to reduce the minimal period.
The Generator / Optimizer had min and max periods fixed to 5 and 50 correspondingly.

Now we can reduce the MA periods below 5 (2 for example) and above 50.
However, this option doesn't affect all of the indicators. It is because some of them have hard-coded min = 1 or 2.

Edit:

Probably, it is better to remove the option and to hard-code the lowest possible limit for each indicator. It will also solve the problem reported by the Statistician here: https://forexsb.com/forum/post/74604/#p74604

- Fixed Journal Export to a CSV format.
The issue was reported by LisaForex here: https://forexsb.com/forum/topic/9427/jo … xport-bug/

- Removed the "Min indicator period" option from the Settings page and the indicators calculation code.
The minimal period the Generator can use is the minimal value for the corresponding indicator.
This update fixes misbehaviour reported by Yoncuro here https://forexsb.com/forum/post/74609/#p74609 and by The Statistition here https://forexsb.com/forum/topic/9425/bu … -generate/

Issues fixed:
- fixed an internal bug in the Editor when we manually set some indicators.
- now, the "Start" buttons of Generator, Reactor, Validator, and the "Recalculate" button of Portfolio are disabled during data loading. This is necessary to prevent issues if we start the corresponding tool while acquiring new data.

Re: EA Studio - News and updates

Uploaded Data Export scripts v6.0

You can download the new scripts from the "Data" -> "Data Import" tab of EA Studio.

New features:

- The new scripts automatically determine the exported file encoding. The possible variants are ASCII and UTF8. The ASCII variant is preferred because the file is twice smaller and easier to import in Express Generator.
If the broker's name, the terminal's name, the symbol, or the symbol description contains non-Latin characters, the script exports the file as UTF8.

- The Data Export.mq5 script includes dynamic spread information in the file. EA Studio and Express Generator will ignore it for now. However, I plan to make the backtester work with the real spread. It is better to have our files with the real spread ready for that smile.

Looking forward to that!

Quick question: do you know a way to automate or script exporting data from every symbol in the market watch without having to do each one manually? It's a bit tedious if you want to compare several symbols across several brokers. I've found ways to do it with expert advisors, using default templates, etc. but it doesn't seem to work with scripts.

    - better error messages if there is something wrong with the data file.

- The "Candle Color" and the "Pin Bar" indicators are available as exit indicators. This issue was reported by Yonkuro.

Re: EA Studio - News and updates

Uploaded Data Export scripts v6.1

The scripts set the exported files encoding better (at least from what I can assume by reading the MQL docs).

Hypothetically, you need to update the Data Export files only if you have problems importing the data files in Express Generator, which will happen if your broker's name is written with non-English characters.

The newest Express Generator v2.45 takes advantage of the fixed encoding.

Re: EA Studio - News and updates

Uploaded Expert Advisor Studio v23.9.5.

This release comes with an updated Validator:
- it validates the strategies parameters when importing files. This fix prevents EA Studio from crashing when loading old collection files (I mean older than 5 years).
- it shows the loaded filenames. This feature helps us to find which collections are validating when we have several running EA Studio copies.

Please report all issues.

> Popov did you get my DM about Daylight Savings Time?
EA Studio uses data from the broker as it is. It is the same as you have when you start trading.
I only hope they will remove DST sooner.

Re: EA Studio - News and updates

Uploaded Expert Advisor Studio v23.10.10.

New features: added support to Real Spread

  - EA Studio can backtest strategies with a real spread. With the latest Data Export scripts, you can have data with a real spread from your MT5.

  - The integrated "Premium Data" feed contains real spread information. The symbols also have realistic Swaps and a preset commission of 3 USD per lot per side.

- The integrated "MetaTrader-Demo" data feed takes data from an MT5 live account of BlackBull Markets. It also contains real spread, swaps and commissions.

- You can see the spread by moving the cursor over the Indicator chart.

- The preset fixed spread serves as a minimal spread. It means, that if the real spread is higher than the fixed one, the real spread is used. The fixed spread is used if the real spread is lower than the fixed one or if there is no spread information.

- MT4 doesn't export spread information. A fixed spread is used When exporting data from an MT4 terminal.

Please report any issues!

Re: EA Studio - News and updates

Uploaded Expert Advisor Studio v23.10.12.

This release comes with minor fixes, which improve the backtest correctness.

Changes:
- Trailing SL for short positions is correctly calculated by considering the rail spread.
- The Level of the "Moving Average of Oscillator" indicator can be negative. It corresponds to the Generator settings, which allow a negative Level to be generated for this indicator.
- Updated Premium Data settings. It uses a $6 commission per lot, per close now. It was $3 per lot, per side before. Now, it will show the same result in Express Generator.

Re: EA Studio - News and updates

Uploaded Expert Advisor Studio v23.10.17.

This release comes with a "Use dynamic spread (if available)" option under the Tools -> Settings page.

https://image-holder.forexsb.com/store/use-dynamic-spread-option-thumb.png

The "Use dynamic spread (if available)" is enabled by default.
It sets EA Studio to use spread information from the data file.

Dynamic spread information is available in the Premium Data in EA Studio and when you export data from MetaTrader 5.
