For those of you who trade only commodity stocks: Is there an advantage to trading only certain sectors such as gold stocks, versus trading off a stock screener? Are there any purely technical analysis traders who trade commodity stocks? Commodity stocks price action seems mostly a result of supply/demand/speculation/etc. Seems very hard to daytrade a stock like ATI, the 5 min bars are like $.50 ? What kinda R/R are you expecting? I suppose other stox like RIO have less 5min volatility...
