The analysis discusses NVDA, focusing on weekly and daily charts. It highlights 179.30 as a critical weekly channel top. A close above this level is needed to maintain the buy signal, targeting 219.64 within 2-3 months. A settlement below 169.88 would indicate a sell signal targeting 149.41. Intraday, 172.96 is a horizontal channel bottom. Closing above 176.49 could lead to testing 178.95-179.30. The QQQ needs to close above its 2.5-year channel top.
