Hi Zoran,
First of all not all the EAs’ in a portfolio will always row in the same direction as they all have different strategies. Some will move in an upward direction, some may move sideways, and some may drawdown all at the same time. Theoretically, this is why you put all the EAs’ in a portfolio so the EAs’ will compensate for each other keeping the overall portfolio profitable. When putting EAs’ in a portfolio you should look at the profit and loss of the portfolio and not the individual EAs’ making up the portfolio.
Secondly, you cannot count on the first EA added to the portfolio as being serial number 000, nor can you count on the second EA added to the portfolio as being serial number 001, etc.
Alan,
