I think it's fair to say that most forex traders have at least one or two issues with their chosen forex broker. In fact most people will probably have a love-hate relationship with their broker. However it's still a good idea to stay in their good books because otherwise you risk losing your trading account completely.
So what kind of things are most likely to upset your forex broker?
Well the obvious answer is to mention the fact that they hate traders who consistently win money from them. This is a natural assumption to make, but it's not always as clear-cut as that because if you do happen to develop into a highly profitable trader, the broker you use to trade with can simply hedge your trades elsewhere, and maybe even profit from them as well.
As long as you are trading independently, you probably won't face any problems if you do start to make some decent profits. What they do not like, however, is for you to use a forex robot on their trading platform. This is especially true if hundreds of other traders are also using the same robot.
Of course if it's losing money then they may not have a problem with it. However if it's a top quality expert advisor that's actually generating consistent profits for it's users, then you may find that it's only a matter of time before your broker bans this robot completely. They may even ban you as well in extreme cases, which is not something that the sellers of these robots will warn you about before you start using their robots.
