I longed roughtly 1M usd with half AUD, half EUR. IB charges couple hundred per week. how does this calculated? Meanwhile, I noticed my Account summary tab from TWS is not so accurate and realtime. Net liquidation value changed to some old value hours ago, and changed back after a while. The avg Cost for some position is apparently wrong. Say I short AUD/USD at x. it showed x(roughtly) for avg Cost initially. Then, after half hour it changed to x+6pips. It's very worrisome to me.
He means Interactive Brokers when he says IB. You're just looking for an excuse to plug your services... go spam somewhere else.
