RE: why the move?Are you a day trader or long term? K traded 15% between the high and lows in 5 hours, whereas IMG only traded 7%. Its good money when you catch it and it was the trade to be in today in gold. IMG was a smaller move, but ended positive. Depends how you trade and we all look at the markets differently, so it depends how you define "moving so much" compared to the % spread.
Good luck!
