As you can see in the graph this is a Falling Wedge and this is normally bullish. The expected gain is based on moving the support trend line right next to the start of the Falling Wedge. The white paths are my prediction on how it may play out.
Let's start off at a positive note, the bullish symmetrical triangle (yellow). For teaching and learning purposes, a symmetrical triangle that start with a high is normally bullish and same goes for a bearish symmetrical triangle but starts on a low(blue).
As you can see it can go either way based on the plotted chart so what we need to look for is a high volume...
