Breakout Out of Massive Flag Looming?, page-44

This page describes descending triangles as bearish, and i think the description fits, if it does break downwards it could get nasty, and expect high volume.
If you take the triangle height to the peak at $3.40, or more consistent pattern from $3.27, and looking at previous leveles, the SP could fall to its previous low of $2.60 or perhaps the $2.75-$2.80 range.

Trend: In order to qualify as a continuation pattern, an established trend should exist. However, because the descending triangle is definitely a bearish pattern, the length and duration of the current trend is not as important. The robustness of the formation is paramount.

Lower Horizontal Line: At least 2 reaction lows are required to form the lower horizontal line. The lows do not have to be exact, but should be within reasonable proximity of each other. There should be some distance separating the lows and a reaction high between them.

Upper Descending Trend Line: At least two reaction highs are required to form the upper descending trend line. These reaction highs should be successively lower and there should be some distance between the highs. If a more recent reaction high is equal to or greater than the previous reaction high, then the descending triangle is not valid.

Duration: The length of the pattern can range from a few weeks to many months, with the average pattern lasting from 1-3 months.

Volume: As the pattern develops, volume usually contracts. When the downside break occurs, there would ideally be an expansion of volume for confirmation. While volume confirmation is preferred, it is not always necessary.

Return to Breakout: A basic tenet of technical analysis is that broken support turns into resistance and vice versa. When the horizontal support line of the descending triangle is broken, it turns into resistance. Sometimes there will be a return to this newfound resistance level before the down move begins in earnest.

Target: Once the breakout has occurred, the price projection is found by measuring the widest distance of the pattern and subtracting it from the resistance breakout.
