EA Studio Tools and Settings: Experience and Results

[Petko Aleksandrov]

I like to use it too! And if one is developing the EA by coding, will never know this option exists 🙂

I am used to place the max consecutive losses in the acceptance criteria.

I think it is great filter because this way we know how many negative trades to expect during the trading.

also if there are more during the demo trading, than I know it is over optimized Expert Advisor

I’m currently testing from 2005 on the H1 for a few of my pairs (roughly 90k bars). I’ve been looking into using 20% OOS and then keeping the last 6 months of data in my back pocket as a final test after Monte Carlo. Today I just threw some GBPJPY strats on the demo account for testing, will let you know how it goes!

P.S. only 2 made it onto my demo account after 20 hours of scanning. Only the strategies that passed the 20% OOS and the 6 months visual check.

Hi Roman,

It is good that you test with the OOS and 6 months at the end. However, you are using huge period, so you can afford it.

Keep in mind that the more Historical data you have, the profit per day becomes smaller. That is why to look for this “golden middle” that will bring you you robust strategies with a nice profit.

Hey guys,

do you know that now it is available to use up to 500k bars in the Data in EA Studio. That is only for the licensed traders by the way.

Have someone tried that?

[Petko Aleksandrov]

Hello,

this increase of the Historical bars is still in test, and I am not sure if it will last.

Anyway, if you want to test it, you need to change the number from the Data Horizon.

There are many updates now in EA Studio, and more are coming up.

So what I will do is to open a new topic in the forum, where I will post videos with every update. This way everyone will keep it up with the updates, and I will explain them in details, because in the help of EA Studio they are written but not really explained.

Hi all,

I wish to know if someone has a strict system when generating strategies with EA Studio or FSB pro about the acceptance criteria?

What I have learned from Petko is to reduce the acceptance criteria if I can not get any strategies and to increase it if I am generating too many.

The thing is that with every asset it is different. I mean if I found good acceptance criteria for EURUSD, this does not work on GBPJPY for example. So I had to lower the acceptance criteria there.

Any suggestions on that?

[Petko Aleksandrov]

Hi Maria,

better to generate more strategies and than filter them in the Collection.

The generator shows different and unique strategies all the time, so you really can not predict what it will show in 100%.

That is why you better give it a little bit more space, and than you just filter the strategies you want to have using the filters in the collection.

[Petko Aleksandrov]

Hello Maria,

one thing to keep in mind here is that the brokers offer a different number of Historical data bars with different assets.

Have a look at your data, and you will see that for EURUSD you will have more bars that for AUDUSD for example.

This difference could change the performance of the generator when using the same acceptance criteria which is logical.

Now when you get used with the EA Studio and you generate daily strategies you will know what acceptance criteria to place for any asset quickly.

Not a bad idea to make an excel table where you place the currency pairs with the acceptance criteria and the values that worked best the last time.

So when you run a generator for any asset you can have a quick look at it, and see the latest acceptance criteria that you used. It will save you time.

[Petko Aleksandrov]

Hello Jacpin,

I get your point. So you just generate strategies with fewer criteria and than you make it strict with the filter in Collections.

Now, I am concentrated a lot on the new feature R – squared and I think I am trying to make my strategies with too good equity lines which is not exactly what I should be doing 🙂

[Petko Aleksandrov]

Hey Andi,

this is exactly what I am planning to do. I think jacpin said the same. Just generate with not so much strict criteria and then make it strict from the filters in the collection.

Petko is doing the same in his courses, so I do not know why I lost a couple of days to struggle with that.

[Petko Aleksandrov]

Hey Petko,

Your idea is just great. I am getting on work to start building such a table.

You are right that it will save me time just because of generating strategies for the same currency pairs will be easier.

With the time I will just make the acceptance criteria stricter.

[Petko Aleksandrov]

Hello traders,

I think it will be great if in this topic everyone shares what acceptance criteria one uses. This was we will have an idea what to test as acceptance criteria because obviously running a generator without good strategies at the end is what we do not want to have.

So here I will start:

Currently, I use:

Profit Factor 1.2

R – squared – 70

Min count of trades 500

Stagnation in % – 15%

[Petko Aleksandrov]

Here are my Acceptance criteria at the moment for the Forex pairs:

R – squared – 80

Min count of trades 450

Max consecutive losses 10

Backtest quality – 98

[Petko Aleksandrov]

Here is what I use in the acceptance criteria:

Minimum bars in trade – 30%

Min profit factor – 1.2

Min months on profit – 80%

May I ask what is the R – squared? I see that you both use it?
