At a first glance, Nividia's chart doesn't look very good.
However, having the middle-term trend in mind, one could argue that the strong price slip could have found an end.
The middle-term average oscillation corridor normally provides a huge level of confidence, and most of the time the price will not tend to leave this area of security.
However, during the last trading days, there was a strong downside breakout, leading to a strong sell-off being supported by rising volumes.
Normally, this is a clear sign for a downtrend. However, the price reached a support zone where enough buyers felt that the current price is low enough for going in cheap.
This opinion is supported by a historical component (support line which was already tested in the past) and the fact that the SMA 200 catched up with the price development. As you can see, the SMA 200 was used as a support line two trading days ago.
Chances are high that the SMA 200 will continue to provide a decent level of support and buys will probably place long orders around that zone.
I went long a bit too early, but still believe that buys will not let the course drop below the SMA 200 (+ 1%). This would mean that there is a good chance for a long setup here, and one could go long with a very small position and extend it as soon as the price continued to stay above the SMA 200 for another 2-3 days.
Please know that I am a bloody amateur in trading, which means you shouln't take my opinion into account when making trading decisions.
Good luck!
