Flags can be an effective chart shape when they appear. Observe how the recent retracement of INF is sort of shaping into a flag off a flagpole. This is normally a bullish pattern. I find often the retracement from the top runs down close to the midpoint of the run up, in forming the flag. Sometimes also, this low point may often rest on a previous top, adding strength to support at such retracement levels within the flag. A technical shape to watch.

Observe also how volume is heaviest at the peak, often a new announcement on the day into which the stock HAS ALREADY RUN UP. Hence on the announcement, the stock is due for a retracement. There is something however that in this instance I don't like about the pattern here. I don't like the heavy selling over the past two weeks. (Volume bars on the downside are highlighted in red.) Have a look at the other flags illustrated here, and you will see what I mean.
