Hello, I've only been using the commercial algorithm for two months and I was the same as timelleston. I had spent weeks considering how to create a portfolio, learning about EA Studio and creating systems. I did not understand how I had systems in various temporalities and pairs that worked on IS and OOS and the second day of testing them in demo they gave catastrophic results. I have read the topic from top to bottom, in some parts I have read it two or three times. (Also the google translation is not the best) and I just want to say thank you. Thanks to all of you who have contributed your grain of sand but above all thanks to timelleston and sleytus. To sleytus for the knowledge taught but above all for teaching us that more data is not better and to timelleston for his interest, proofs shown and making the thread move forward. You've all done more than that but I'm not going to get romantic.

I have taken your conclusions with which I agree and I think I have found something, and if I am not mistaken something very good and how I have come this far thanks to you I would like to share it, although I have not done more than 20 tests I think there is a clear advantage. Although it is best that you try it since I am not going to show any results, since I have been with the portfolio in demo for a day, but in backtests with similar strategies and "end date" in the past to see results in the future they work a time.

As sleytus says, the strategies (and especially the ones we were testing, I have also tried everything shared in the topic and a hundred more combinations). As he was saying, the strategies are very adjusted to the sample and the market is changing. And these two go hand in hand. I have only made the market less volatile by raising the time frame to 1H. Why? The candles are more summarized and this means that we collect more data in the same number of bars, we minimize the noise that we talk about so much. For example, if we take 500 candles in 15 min and we are in a strong uptrend, it is very likely that the trend will change its volume and the system will start to fail. If we do it in 1h, can the trend catch us and what happened before it and we eliminate x4 noise?

And I have worked with data of 6175 bars, which has been a year in 1h. With less it has not gone well for me and I have been going up until I found that one. It is obvious that it can be better adjusted to this way of operating. I'm going to stop spinning and I'm going to say the settings.

I work with 6175 bars from my broker.
EUR USD in 1H (one year)
short and long
reverse signal
Fixed or trailing stop of 200
No take profit

Better return/drawdown
in the sample
Max indicators 2 and 2

Walk Fordwalk:
Segments: 4 Validated segments: 3
30% oos and 20 steps

Monte Carlo:
Tests: 20 and 50% validated.

Criteria of acceptance:
Minimum net profit: 100
Min. number of operations: 200
Max Drawdown: 12%
Max Stagnant days: 60

Then I leave a day and something else for the reactor to think about and order the collection by SQN. This puts us at the top of the operations with less DD and they rise exponentially, that is, if the sample is one year, in the last six months it has been working better and I remove those that currently (an imaginary 10% OOS) are in DD . Because I only want systems that are currently winning, that my system has worked in the last year but in the last six months better. And I normalize, (this above all touches our stop of 200 in many cases it is very big.)

In the tests I've done, none of them crash like we used to, the systems that don't work stay in range for a bit and then lose and the winners win. From there I made a portfolio of at least 20 experts for my opinion and remove the stagnant or losers and leave winners. Considering that our systems have a great curve for the short amount of time. But in this systems management I am very new, as in all this. I am 26 years old and I have never made money consistently but I think I have improved somewhat the results we had. I would like people to try it and modify this concept to find a more optimal way if possible.

How do you "set Max Open Trades to '0'"?

This doesn't exist for single EA Studio EAs, they don't have this option and that's what he was referring to.

Yes.
You're not trialing? In trial version you should have full functionality also, gives you an idea how it works.

My bad, no exporting function in trial mode.

Yes, the max open position feature is an input for portfolio EAs.

As a long term quantitative trader (doing this since 2008), I follow a rigorous methodology to ensure that my trading strategies are based on robust data analysis. Specifically, I utilize a vast dataset spanning from 1987 to 2017, with a limiting end date as yourself. Subsequently, I retest the resulting strategies on a more recent dataset from 2017 to present. Upon passing stringent stability tests and meeting my performance metrics, I promptly deploy the model into the live trading environment. I have found that this approach is most effective for obtaining consistently favorable outcomes. Conversely, I have found that attempting to use short timeframes such as days, weeks, months, or even ten years of data does not yield any satisfactory results, it´s just almost always randomness with short datasets and you simply can´t tell if there is a real edge with such short horizons. Only by incorporating my comprehensive Forex dataset spanning back to 1987 am I able to achieve the stability and profitability.

Congratulations on your remarkable results! I am curious to know how your portfolio performed during the months of March, April, and May (up until now).

I'm delighted to hear that your method is yielding positive outcomes for you as well. My approach, which I find to be rather stress-free, involves running the generator continuously, reviewing its findings approximately every two weeks, subjecting it to rigorous stress tests, conducting six years of out-of-sample testing, and only implementing it live once it successfully passes all evaluations. It's a straightforward process.

Based on my research, I have observed that the longer the data horizon utilized, the less susceptible the systems are to curve fitting. This is primarily due to the difficulty of fitting such vast datasets through random chance alone, thereby enabling the models to generalize across various market conditions. Consequently, this enhances their chances of survival in the future.

I'm eagerly looking forward to witnessing your progress as well. Wishing you the best of luck!

Good afternoon everyone,
found this interesting topic in testing on just 300 bars.

Before reading it all, I started generated with EA Studio for EURAUD based on the The5ers prop account data.

Had no success after a couple of portfolio, for where I need to close trades manually and got huge drawdown the first day already.

I then saw some posts talking about CADJPY and GBPJPY, @sleytus and @timelleston are still they your best pairs now?

At march 2024, how much bars are you using for generating?

Would love to know your updates and overall result.

My current approach for data used and strategies selection (to put them in the portofio):
500 Bars
No OOS
Small optimization only on SL/TP (+-10)
Not always: Preset indicators: 3 bars rising (BB) + MACD live above signal line (both for trade with the trend)
M15
WinLoss ratio 1.0
Minimum trades 10
SL 10-30 pips
TP 5-30 pips
Drawdown: max 10usd (testing 0.1Lts with 5k)

Do you keep 2 correlated strategies in the portfolio or do you remove them? And how (trend, similar rules, both)?

Please share any feedbacks and updates you feel!
Thanks
