Hi all, After a small adventure on the forex markets and a break afterwards I'd like to get back in the trading game, so I started paper trading using the IB demo account in TWS. I know there is quite a difference between live and demo trading, but I am a bit worried that the IB demo feed is too far off for my needs. Especially Level II or DOM. For example, when I look at the Bid Ask spreak for the most active US stocks I see a couple stock with more than 1% spread on a ~$20 dollar value and ~5M volume. A strategy trading this spread like DayTrader10 suggested in http://www.elitetrader.com/vb/showthread.php?s=&threadid=244373 has high rate of success in this scenario, raking a few dollars every turn, see attachment. Is this a true market condition or is this caused by the simulation inefficiency of IB demo sytem? Are there better paper trading solutions around?
