Being Kicked Out Without Any Warning

Several months ago, Oanda suddenly kicked me out of my position without any warning. I was in a good profitable place, it was well above my stop loss. I thought there must be some mistake so I talked to their customer support and I didn't get a clear explanation about why such a thing happened. That is not the only time I had a problem with this broker. Recently, I also find out that Oanda suddenly wiped out my account due to an inactivity fee. It wasn't even that long since I'm not really active, but that is just because I was holding positions, they can well see that I still have an open position. There is no reason to kick me out.
