Hello, i am a long time equity trader, short time fx trader 
I would really appreciate answers to my noobish questions, thanx in advance.. Anyways:
Just opened an account with IB and I have some really important questions....
As a test, I went long on jpdy/ usd 25,000...
I sold at a few pips loss, and I was suprised to see i had -249 YEN in my account... I phoned IB but I am still unsure of why the hell this happened. Now i have to sell it and pay extra commission. The interest from this amount is basically nothing so I will clearly not sell it. Its just a damn annoyance.
Do all FX pairs work like this? What if I had a gain of 500,000 yen? Would it be put into my account in yen?
What If I went long on EUR/USD and profited 200 EUR, would I get a holding of 200 EURo's in my account? If Why don't they just convert it back to US?
Can someone clear this up for me?
Also I dont understand how interest works... Sometimes I get interest charged against me, but sometimes we get interest in our favour? How does this work?
thanks
