Quote from RCG Trader:
I put these in my stock database I keep. It looks like a good way to do commodities for people like me who are scared to death of that limit up/limit down thing. I heard horror stories about that years ago about people being caught on the wrong side of a strong up draft and essentially being destroyed.
As far as limit moves go, "usually" they are in the direction of the trend. Probably 90%. Faders, please for the love of your family, don't trade commodities. Stick with stocks or indices. Commodities are all about trends. And there is no such thing as over bought or over sold.
