Topic: Is there currently any way to increase the collection capacity > 300?

Hi :-)

I need to de-duplicate a large collection of strategies and hence temporary need to increase the collection limit to 1000. I know that this will be slow, but it does not matter, because I can only really de-duplicate my whole strategy collection if they all go to one big strategy collection, otherwise, if doing it in 300-batches, dupes will remain.

So right now, the max we can select is 300. There also seems to be no way anymore to increase it via the console, which was possible before. How can I increase the collection size to 1000? I really hope there is a way still like it was possible before.

Thank you :-)

There is a dirty way to do it, but it is not tested.

Open EA Studio directly here: https://eas.forexsb.com
Open the browser's console: hit F12 and switch to the "Console" tab
Write the following statement:

eas.settings.collectionCapacity = 1000

Other EA Studio internal variables can be also changed at your own responsibility.

These are the default values:

eas.settings.initialAccount     = 10000
eas.settings.leverage           = 100
eas.settings.minDataBars        = 300
eas.settings.maxDataBars        = 100000
eas.settings.collectionCapacity = 100

yes that is really good to know. so we can local make our changes like we want and need.

Ahhh nice, I hoped it would still be possible via the console. I will try it this evening. Is there a complete list of EA Studio variables that can be changed via the console?

Very smooth equity curves, what kind of acceptance criteria do you use?

Nothing special, basically just optimizing for best R-Squared with some minimum amount of trades and ret/dd. The curves look so smooth because it´s 35 years of historical data.

Re: Is there currently any way to increase the collection capacity > 300?

@Popov: is there a variable that I can change via the console so that the "Validator" and the collection allows strategy entries with a negative balance (< 0)? That would help a lot. Right now it seems that there always is a forced acceptance criterion that any strategy that passes the Validator or is in the Collection needs to have a net profit > 0. In theory, this makes sense, but for special tasks like re-validating old strategies, it´s not good, as they simply get deleted this way.

so that the "Validator" and the collection allows strategy entries with a negative balance

Done!

The Validator pushes all strategies to the Collection now, provided that you don't use Acceptance Criteria or other validation tools. Please be sure the Collection filters are off also.

Great, it works fine - thank you!

Is there a list of all variables that we can alter via the console? I am for example looking to alter the initial randomization range for the lookback periods of indicators. As far as I see, EA Studio randomized the period for indicators up to a max of 100, but I´d like to that it randomizes up to a period of 200.

Thank you.
