Hello Petko and trading friends,
After some time of working around with EA Studio, I’m impressive with its capacity of creating nearly infinite numbers of Expert Advisors. However, the key point is we need to have a good combination of common acceptance criteria so that it can generate enough good Expert Advisors in not too long time. That’s the point where Petko’s experience comes into play to help us. I suppose many of you are having the same questions below and I hope Petko will help us with it.
1a) What are your frequently used Common Acceptance Criteria and their frequently used values?
(I know we may have many combinations of common acceptance criteria such as minimum count of trades, minimum profit factor and it depends on the taste of each trader. The more acceptance criteria, the longer it may take to find a strategy. However, I believe after a long time of using EA Studio you find a good balance point, where we can set common acceptance criteria to generate good strategy but don’t cost much time for weeks or months to generate.
1b) In a course, you have set the following Common Acceptance Criteria: 1. Minimum system quality number: 0,98; 2. Minimum r-squared: 60; 3. Minimum profit factor: 1.2; 4. Minimum count of trades: 350. Are these criteria often used by you and in accordance to your experience of trial and error, are these criteria good enough for EA Studio to generate decent strategies?
1c) Do you use any other combination of Common Acceptance Criteria in addition to the above frequently used ones (mentioned in 1a, 1b)? If yes, may you please share your experience with us?
2. Usually how many Calculated Strategies (I mean the total number Reactor has generated, not the strategies put into Collection) have you had each time?
(Initially, I wanted to ask how long do you run Reactor each time, however, I think this question is useless since it depends on the power of each one’s computer. If your computer is so strong, you only need one night to generate totally 3 million strategies and that big number of strategies could provide decent final good strategy to put into Collections. So I’d better ask how many Calculated Strategies you have for each run so that I can calculate the needed time to run).
I have some more questions, but I think it will make my post too long. Furthermore, I want to have more posts so that Petko will give me discount for his course as promised. So let me post another question on another post.
Thank you Petko and trading friends in advance for answering me.
Cheers,
Viet Cuong

Hi Petko,
Is it possible to set the EA for EA Studio to close all trade on Friday? I tried the below setting, it seems not the way I want it to be.

Hello, and welcome to the Forum!
Glad to hear you have many questions. This means that you are getting into the details.
1. It is important to find the balance of acceptance criteria for your Historical data. The number of bar matters here. If you have a small number of bars and you set strict acceptance criteria, you will not see any strategies in the collection.
Yes, these are criteria where I follow and do some changes if it is needed.
There is a Topic in the Forum about the Acceptance criteria, and many traders shared their way.
Simply, start with any acceptance criteria that you find logical, and you will see if you need to stricter or not.
It is better to have more strategies in the collection from where you can filter again.
2. When I generate strategies, I want to have at least 10 strategies that passed all the criteria and robustness tools.
Depends on the asset and what the plan is for the trading, sometimes I go for above 30 or 40. Just leave it longer or loosen the criteria.

Hello Simon,
Yes, you need to check the Friday Close, but you need to change the hour.
What time does your broker close on Friday? If they close exactly at 24:00 you need to change it to 00:00 – 23:45.
Because the EA will execute the close after the new bar is opened, and if the market is closed, it will not be able to close the trade.
So just do it 15 min before the close.
-
Thanks petko,
I needed that too.
Most times charts do not continue exactly where it ended on Friday, which could negatively affect previously opened trade by the time markets opens on Monday.
-
Hello Augustine,
This is because there is Sunday trading which most of the brokers with MetaTrader don’t show. It is available with some of the paid platforms.
This is why there is a gap between Friday and Monday.
However, that is not really an issue because we use the Historical data where Sunday trading is not included.
So the EAs are expected to handle it. Don’t spend a lot of time on that.
Regards.

Hi Petko,
I have some EAs which are performing exceptionally well. Problem is, I can’t remember exactly which settings I used when creating them.
Is there a way to know, through EA Studio (or any other way) the settings which were used to create them? Perhaps upload them to EA Studio to reverse engineer them? Apologies if this is a silly question.
Thanks,
Ilan

Hey Ilan,
Glad to hear that you succeeded to create EAs with good results.
I don’t think you can understand the settings you used.
What I do is to keep a spreadsheet with all the settings I use for the different set of EAs.
For example, I have a column for the EURUSD strategies where I used 1.2 PF, R- Squared 80 Sl range 10-50 TP Range 50-90 etc.
And then I organize the EAs in folders according to the settings I used. So far I think this is the easiest way to organize your work.
Another thing which requires a bit more work is to organize your EAs using the Magic Numbers. For example, you can use the first 2 symbols for the currency pair. 01 – EURUSD 02 – GBPUSD. After that, you can have the Time Frame 05 – M5, 15-M15. Then you can have the acceptance criteria which you selected to use.
Hope these tips might give you a better idea of how to organize your work.

Hi Petko,
In the Tools menu of EA Studio, where one can change the Trading session times – which time zone is this in – GMT, my local PC time, etc?
Thanks, as always.

Hi Petko,
In the symbol settings in the tools menu of EA Studio, where you can add the commission amount, would that be commission for a full 1 lot (assuming the lot size settings is 100,000)? So if I am creating strategies for an entry of 0.01 lots, an the broker charges $7 for 1 lot, 0.7 for 0.1 lot and 0.07 for 0.01 lot, does the system automatically adjust the commission, or do I put in commission for the 0.01 lots?
Thank you,
Ilan

Hello Ilan,
no, you need to synchronize it with your broker’s time.
Some brokers synchronize the time with your local but some don’t.
To make it sure, you can look at the market watch, and see what is the hour with the broker.
-
Hey Ilan,
You place it for 1 lot, and the system will calculate how much it is for any different quantity.
Cheers,

Thanks Petko

Perfect, thanks as always

I use EA Studio to generate EA’s for Crypto.
However I’m not sure how to get all the symbol settings correct.
For example, say I am using a crypto that has a price of $.55555.
In custom symbol settings I set the digits to five and that uses the correct prices.
But I’m not sure what number the spread should be set at.
The actual spread I’m trading at is $.00005
When I import the data its setting it at 10 in the symbol settings. Is this correct? I could use an in depth explanation of how it calculates it and what happens when you change digits.
Also how can I properly enter the commission? Is value you enter for entry and close, or just one side of the trade?
Say my commission for entry and close, both sides of the trade combined = .1%. So actual commission per 1 lot with a price of $.55555 is $.0005
How do I enter that into the symbol settings under commission?
Also I usually raise the lots in the symbol settings so it will be trading 100 lots. That makes it easier to see the balance in the charts.
But sometimes if I put in 100 for lots it actually trades 1000. If i set it to 10 lots it trades 100. Why is that?
Also, by changing lots does that affect the way I need to enter commission? Is commission based on just 1 lot or the number I have entered under lots?
Thanks for your help to clarify all this.
-
Hey Jammerly,
Yes, you should make the symbol settings exactly the same way you see it with your broker.
The commission depends on the brokers. Some charge one time, others twice.
Can you upload some screenshots about the lots. Where do you see the change, in MetaTrader or in the EA Studio backtest?
Cheers.

When I download my EA collections they go to my laptop Download file. I there a way to download my EA collections to another file?
-
Hi Alan,
I assume you mean download to another folder?
This is controlled by your browser. Just go into your chrome settings and change the default download folder in there.

Thank you!

I took EA Pro course watched all the video. On EA Studio trading sessions option. Do you enable or disable it? I know swap charges holding pairs overnight. How about no trade on Sunday? I know on my own experienced Sunday spread are very high. Any advice pro and cons? Thanks!
-
Hi, New member purchased the EA professional course. On the trading Sessions option. Check all boxes: do not trade on Sunday, close at the end of the sessions and close at Friday close? or leave it uncheck? Pardon my grammar second language.
-
Patrick,
If you want to trade 24/5 then you do not need to do anything with the Trading Sessions option. If you want to limit trading to certain hour then all you need to do is to adjust the range of trading hours for the days you want to limit trading. If you do not want to trade on Sunday to avoid high swaps then all you need to do is to check the box “Do Not Trade on Sunday”.
Hope this helps!

I answered these questions in your other post.

Hi Patrick,
Yes just set things for how you want to trade, also if you are intending on doing prop challenges then need to meet their requirements, for example some don’t allow open trades over weekends.
Also it’s a good idea as you have said to avoid opening trades during high spread periods.
I would definitely recommend customizing your setting a for how you intend to trade before generating.
-
I have another question about Trading Session.
What time zone are the Trading Sesion filters using?
Like are they using the time zone of your data? Or are they using UTC time?
-
Yes, it is the timezone of your historical data. This is what EA Stduio uses.
-
Let’s say I want to see how my strategies have performed over the last month, but I can’t because there are only about 137 4hr bars in one month. What do I do? I set the minimum number of bars to 100, but when I refresh the page, it returns to 300.
-
EA Studio needs these 300 bars so the indicators used in the EA will have a sufficient lookback period so they will start working correctly over the time frame you are interested in observing. 300 bars where each bar is 4hrs indicates you need at least 3 months of data history. Are you using your broker’s historical data? If so you need to maximize the broker’s history data in MT4. If you don’t know how to do that I will provide a link to a video to show you how this is done. The other option is to use the Premium Data in EA Studio.

Hi, my name is Simon Watti and I would like to first convey my profound gratitude for the great service you are offering people like me. I started forex trading almost three months ago from scratch and was fumbling around in the dark till I watched your introductory guide to Algorithm trading. and I am not turning back. Thank you for the 50 free EAs I got a few days ago, I have put them on my demo account to filter those that are compatible with my broker’s data (Exness). I actually generated and downloaded twenty EA from the EA Studio and also put them on the demo account. My challenge is that I had not learned how to keep them in the collection and just deleted them and yet I may need them again for recalculation seeing that I am not generating any more now (I do not know why because I am using the same settings as guided in the videos and user guide). Kindly let me know how to convert the downloaded EAs to JSON format that is required for the upload to the EA Studio.
Thank you so much once again. Kind regards. -
Simon,
Select Validator and drag and drop EAs into the Strategies box.
Or, Click on the Strategies box, navigate to the EA, click on EA, and click on Open to import EA into the Strategies box.
Uncheck the Acceptance Criteria box.
Uncheck all these boxes.
Click on Start and all the EAs will now be back in the Collection.
-
Hello I was wondering how can i add a Dashboard to the EAs along with the Daily Drawdown protection and Over all account equity drawdown protection? Thank you
-
Hi Balfred,
When you create Expert Advisors with EA Studio the downloaded EAs when installed on MT4 or MT5 will have a Dashboard showing the status of the EA. The EA will also have Daily Drawdown protection, account equity drawdown protection that can be setup in the EAs properties dialog box.
Alan,
