Strengths and Weaknesses
As outlined earlier, the continuation of an uptrend takes a specific form. This form, in this case the ascending triangle, helps us define the trading environment. On one hand, a break of the upper trend line signals the continuation of the bullish trend.
On the other, a move below the supporting line breaks the series of the higher highs and invalidates the entire pattern. In this case, the followup is usually a strong move lower as the buyers missed their chance to continue the uptrend.
Thus, this is the main strength of the ascending triangle - it helps the uptrend to extend. Due to the existence of two trend lines, we are in a better position to determine the take profit and stop loss, if the pattern is activated.
The biggest limitation of the bullish triangle, as it’s the case with other types of triangle, is a false breakout. The price action may move above the resistance line, just to return below, and hit a stop loss. In order to minimize the chance of a failed breakout, it’s always advised to consult other technical indicators and confirm the breakout e.g. volume, RSI etc.
Moreover, consolidation of power takes place as the two lines converge. The narrower the wedge gets, the stronger the breakout usually is. Hence, this amount of power and strength can’t always be controlled, and therefore, it may end up in the price exploding in the opposite direction, although the chances of a continuation of the existing trend are always higher.
