A question about how one would go about "refining" a collection...

Suppose I have a collection of 100 EAs and use Portfolio Expert to download it as a single EA.  I then attach it to a chart in a Demo account.  And suppose that overall the trading goes well, but there is one EA (e.g. 10057) that is clearly a loser.  And I want to remove it from the collection.  Using EA Studio, how do I know which EA to remove from the collection?  I assume it would be the 57th EA -- but it seems like one thing that is missing is a way to better identify specific EAs in the collection that would make it easy to refine it (i.e. add and remove specific EAs).

Please don't take this as a complaint -- it certainly is not intended that way.  Just some feedback to help me (and perhaps others) take full advantage of this wonderful tool.

By itself I'm not sure that re-importing is sufficient.  My MT4 Account History shows me that EA 10057 keeps losing and I would like to remove it from the collection.  So, even if I can re-import back into EA Studio, then how do I know which EA in the collection corresponds to 10057 so I can remove it from the collection?  Would I edit the mq4 source file and delete the 57th strategy from the strategyList[] array and then fix-up the indices?

Hello.

On Demo its work fine.

Is it ok, when i put it next week on Real? Or make you changes on it, that it for real to risk?

Thank you

Okay, thank you for Answer.

Please write, when Live Trading is ok.

Thank you

Hi Popov,

As a follow up test, I took the same bundled Strategy on another account and manually modified the *mql4 file's lot size [static input double Entry_Amount=0.16; // Entry lots]  and manually compiled again and then attached the strategy to the chart screen.

That did not seems to help and the open positions are all still set to Entry Amount = 0.5. I am not sure where is the cause of the Entry lots size error.

Kasid, you are right,

The portfolio expert trades the amount set in the individual strategies.

We have to choose what is better:
- To have an option in the Portfolio Expert and all strategies to trade equal amounts. It will be easy to set.
- To remove that option and to allow each strategy to trade individual amount.

Es ist eine ziemlich geile Sache. Wir müssten dann allerdings in der Lage sein, die schlechten Strategien zu entfernen.

Die Idee ist grandios. 300 Strategien auf einmal testen .... dann eine Handvoll richtige rauspicken..genial

New version of the Portfolio Expert is uploaded.  Now the "Entry Amount" parameter in the expert input sets the trading amount of each containing strategy.

in order to update your expert you have to do the following:
1. Upload your collection
2. Recalculate the collection
3. Export a Portfolio Expert

Hello

When i save The Portfolio Expert with 100 Strategies, can i load this later back in EA-Studio?

Thanks

Is this is the method used to filter the strategies at this point in time?

Can I have more than one portfolio EA on one account? How would the magic numbers differentiate between each other?

Ahh, yes, it is important to save as a collection first. You able to upload the entire collection again in the format of a .json file.

I have asked the same question in regards to uploading a Portfolio EA. I am unsure of how to do this...

I can only see the option to upload the .json file, not the .mql file.

Hopefully we can get some help with this.

If I edit the MQL source code and change the default Magic number to another then this should solve the issue?
