Autodesk, 4th Wave finished?

Autodesk seems to have completed a Expanded Flat correction, Question is, is the C Wave finished or does it still has some downside to run? Well, if it can managed to hold the previous lows then more likely we will see price coming down to the 161.8% Fib Expansion, that would gives a perfect spot to buy it. Losing that level might tell us that the correction might not be over yet and we are looking at a different pattern.
