It's difficult to keep up with the updates since they come out at random times. As a result I've only tested your EAs 3 separate times and while the combined result was positive I definitely wouldn't ever trust using this on a live account for two reasons: First of all, it's too difficult to get enough testing in with the way updates are posted. Second of all, each news release requires a completely different EA. Is there no way to release a somewhat gereric EA with variables to change? I can't imagine there are too many differences between each EA and it seems ridiculous to have to download and install a new one for every news release. There has to be a more efficient way...
If, for some reason, that's not possible and you're not interested in handing out the source, could you at the very least post updates ~24 hours in advance? I don't think I could ever trust using it live knowing it's a completely different EA each time (for various reasons)...but at least I could test them all and give you some more conclusive feedback.
Well, how are you trading with black box? Don`t you have any fear? Hope on demos.
Here is good EA for trading news with open code and variables to change.
