$NVDA and Elliott Wave.My reasoning;
Wave 2 of the Wave was a Zigzag from the weekly time frame, and as per the rules, Zigzags must be followed by Flats in any correction-- meaning our Wave 4 must be a Flat. Indeed, Wave 4 is a Flat, seen clearly in the daily time frame and it begins after Wave 3(in Black), with a three wave move that is not deep enough to be a correction. This is normal for Wave A in any Flat and is labelled in Dark Blue. After Wave A was completed, we would expect a Wave B and as per the rules, Wave B must go beyond Wave 3's ending. This can be clearly seen in both the daily and weekly time frames. Back to the daily time frame and we can take a closer look at Wave B that is still unfolding. Elliott rules dictate that B must be a three Wave move with two impulses and one corrective wave. The first impulse was formed and the second(corrective) was a Flat which is a corrective structure. Now all that is left is the third wave which will be the second impulse that will complete the Wave B(Dark Blue). Upon completion of this Wave B we could expect a Wave 4 to the downside.
All these Waves have been measured by the Fibonacci Retracement tool.
