DELAFIELD, Wis. (Stockpickr) -- Professional traders running mutual funds and hedge funds don't just look at a stock's price moves; they also track big changes in volume activity. Often when above-average volume moves into an equity, it precedes a large spike in volatility.

Major moves in volume can signal unusual activity, such as insider buying or selling -- or buying or selling by "superinvestors."

Unusual volume can also be a major signal that hedge funds and momentum traders are piling into a stock ahead of a catalyst. These types of traders like to get in well before a large spike, so it's always a smart move to monitor unusual volume. That said, remember to combine trend and price action with unusual volume. Put them all together to help you decipher the next big trend for any stock.

This move is quickly pushing shares of DAN within range of triggering a major breakout trade. That trade will hit if DAN manages to take out some near-term overhead resistance levels at $20.35 to $20.50 and then once it clears its gap-down day high from last October at $21 with high volume.

Traders should now look for long-biased trades in DAN as long as it's trending above Tuesday's low of $19.15 or above some more near-term support at $18.78 and then once it sustains a move or close above those breakout levels with volume that's near or above 2.78 million shares. If that breakout triggers soon, then DAN will set up to re-fill some of its previous gap-down-day zone that started near $23.
