Hi Superalf,
That pair did not trade last week. However, it will continue to trade in the future. I trade 10 different EAs in my Infinity Forex Fund challenge and in some weeks certain EAs do not trade for a week or two and then they start trading again. So, this is normal. Further, you may pick some robots that traded last week but one or two of them may not trade next week. This is why it is a good idea to diversify.
Alan,
