Can you trust the opinion of an IB?

I have a chance to trade with an impressive EA, it’s not bought but has been making nice performance privately with an STP Broker.

The IB or developer whatever you want to call it has provided reports, statements and investor login details.

Question is can I trust the IB fully? I mean I know I can stop trading if I want to, but what if my investment is lost in a few trades?

Whats the opinion?

One thing you must understand about EAs is that they do not always work on the long term. You must judge based on how long the EA has been consistently making profits and ask the developer how long it will continue. There is no perfect EA, which is why you must find out how much can be lost should the Market moves against it. Whether you can fully Trust the IB or EA is your decision to make.
