RectangleADBE appears to have been in a symmetrical triangle, then broke up from the triangle briefly, came back in and then broke down from the triangle.
ADBE looks to be bouncing around between the trendlines of a rectangle or a horizontal trading channel.
You can find mid rectangle by subtracting the lower boundary from the upper boundary. This can make a good stop whichever way this breaks.
Rectangles are a neutral pattern like a symmetrical triangle until a break occurs one way or the other.
