Thanks for your quick reply...
I don't want to explore trader result, I'l like to know wich strategy is best performing within the Portfolio...
By using the magic number in MT4, I can find easly the best strategy, but I don't have any reference to the strategy ID as used in EA Studio.
Here's the details of I'dd like to do :
1. Generate a portfolio of strategies
2. Run the Portfolio EA in MT4
3. Find the best performing strategy in MT4 (by using magic number)
4. Back to EA Studio, and get details about this strategy (and create a EA)
Thanks again for your help
