If you're bullish on SSH, then I would look for long-biased as long as it's trending above its 50-day $6.35, and then once it breaks out above some near-term overhead resistance levels at $7.50 to $7.65 a share with high volume. Look for a sustained move or close above those levels with volume that hits near or above its three-month average action of 66,342 shares. If that breakout triggers soon, then SSH will set up to re-test or possibly take out its next major overhead resistance levels at $8.50 to $9.80 a share.
