Hey Pete,
this is what everyone is looking for – fully automated trading. Now many decide to interfere the EAs after they see some negative results when there are hot economic news.
I receive this question so many times: Should we pause the EAs on the news? And to be honest with you, so far I can not provide 100% answer to that.
On one side is the fact that we can limit a bit the risk(but in the same time we can miss profits)
On the other side is exactly what you say, we generate the EAs over all the data, so they should work during the news.
I keep on looking the right answer, but probably it won’t come.
