To have a valid I look for a 0.618 of the XA leg which is the point B.
Then I need at least a 0.618 from the AB leg but not beyond point A. This gives me the point C.
At last I look for entry at the 1.272 of the AB leg.
I enter with 2 positions. Stops need to be above the X point. My target 1 is at the 0.382 from A
to D. Target 2 is at the from A to D.
