The analysis focuses on NVDA's weekly and daily bar charts. A weekly close above 179.82 suggests a buy signal, targeting 219.64 within 2-3 months. A close below 178.04 would limit buying pressure, potentially inviting a long liquidation to 149.64. Intraday, resistance is at 178.22 and a rising channel top at 187.24. Breaching 183.30 can enable a push to 186.39-187.24. For the downside, 175.55 may contain selling, but a close below this opens up the 170.93 level. A drop below 170.93 enhances a bearish case towards 161.02 in the upcoming weeks, which increases the likelihood of reaching the 149.64 level.
