Hi,
i use EG for generating strategies and get collections over eg 1000 strategies. Than i upload some collections that i have eg 10000 in the Collection. When i now Recalculate them EAS only show me 300 strategies. Why @Popov didnt you change that we can have more than 300 in settings.
Hello Roughey,
> Why @Popov didn't you change that so we can have more than 300 in settings?
I want EA Studio to be maximally helpful to you. However, I am fighting with the browser and some design limitations.
EA Studio stores the Collection in the browser's Local Storage. Its size is not documented. I have experimented with the number of strategies and discovered that the Browser cuts the data if it exceeds its limitations. This damages the stored collections and settings, and it becomes a big mess.
I suggest you use Express Generator to sort/filter the strategies to a workable size.
For example, I pass my generated collection through data from different brokers, and I finally receive from zero to 20-30 strategies per market. (USDCHF has been especially difficult in recent months !?)
Be sure you have the proper commission set. The Commission has a huge impact when there are many trades.
Hey guys, to avoid the problem Popov mentions, I created a script in Tampermonkey that automatically downloads the collection every 15 minutes and deletes it to start over. This allows me to have many collections divided into different files without overloading the browser. I've attached the script. I hope it helps.
Very hacky!
It Goes to the Collection page, downloads the current Collection and clears the Collection page.

Ok didnt know that it make such problems.
My workflow is right now.
EG is generating strategies and collect them. Save them every 500.
Now i have a folder with 10000 collected strategies also from dates of the past.
But i want to check if they were profitable like a forward test with real data.
But what die EAS do. I see he is calculating but it stops at 300. Now is EA adding better strategies and throw bad out?

EA Studio calculates all the strategies. It sorts them according to the "Sort collection by" metric.
if a new strategy arrives, the collection puts it in the correct place. Than, it calculates the Correlations (if enabled).
After resolving the correlated strategies, the program checks the Collection's length. If the length is higher than the selected ones, the program removes the strategies from the bottom.
The EA Studio Collection works in such a way, that keeps the best ones at the top according to the selected sorting and filtering criteria.
