Broker's account managers do not help clients to trade without his/her knowledge, but if clients are willing to accept their guidance or recommendations (signals, or signal providers) then they should be well aware of the risk. Since your account manager offered to guide you along the way, perhaps it is out of his/her good intentions to help you get familiar in this forex industry so you will be loyal to them as their client and not leave them. You can try and see if you're comfortable with his/her guidance and if it goes well with your trading strategy.
