You really want @haejin's answer here... but anywa, I'll give it a try:
looks like a upward trinagle to me. That means the minimum target is the green vertical, which is equal to the "short leg" of the triangle, moved to the tip. Like following the arrow in my graphic. Then I think triangles happen in abcde waves... which, by the way, don't really need to hit the sides.

Now, if it breaks downwards through the hypotenuse, it probably goes back to where it started, but any break must be decisive... otherwise it may be a bullish/bearish wick.

Take it with a grain of salt: I'm still learning. Just check my blog to see two misserable fails!

Also, english is not my native language, so triangle parts translation may be wierd.
