Traders should now look for long-biased trades in SLCA as long as it's trending above $21.24 with strong upside volume flows. I would consider any upside volume day that registers near or above its three-month average action of 744,284 shares as bullish. If SLCA can maintain that trend, then this stock will set up to re-test or possibly take out its next major overhead resistance levels at $25 to $26.
