What it is
The weekly chart smooths out the noise of single days. Say the weekly close is above the 10-week EMA, and the 10-week is above the 30-week. The stock is then in an uptrend on a timescale big institutions care about. A daily setup that agrees with its weekly chart has bigger money on its side. One that disagrees is trading against that money.
How Breakaway uses it
W.EMA fires when the weekly close sits above the 10-week EMA and the 10-week is above the 30-week. Once lit, it stays lit until the weekly close is more than 1.5 percent under the 10-week, or the 10-week falls more than 0.75 percent under the 30-week. It is a trend check worth one point in the check count, where the Quality Score starts. It is also why a stock that looks strong on a daily chart can still score lower than one whose weekly picture agrees.
How to read it
A stock with MA FAN lit but W.EMA dark is usually early in a turn. The daily averages have stacked and the weekly ones have not caught up yet. That can be an early turn that holds, or one that fails. When both are lit, the trend is confirmed on two timescales. Pullbacks are then more likely to find buyers.
