Been trading QID daily for the past 2 months. Green every day so far... the closest I have ever come to free money. Learn to recognise the extremes (then the stall) and buy. Holding anywhere from 15 minutes to 2 or 3 hours. Look for MACD crossovers, enter and place a 10-15 cent stop. The market always gives something back.... almost every day... and QID is a great way to play these pullbacks/pauses.
It beats the hell out of BRCM, AAPL, SNDK, NVDA, etc.
