In the daily Japanese candlestick chart of NVDA, below, we can see a hammer bottom reversal seven sessions ago. A bullish close happened the next day giving us confirmation of the bottom. NVDA made a successful test of the rising 200-day moving average line and is currently challenging the declining 50-day moving average line.
Trading volume has been strong in March as prices rallied but still less than the pace seen in February. The daily On-Balance-Volume (OBV) line has been firming since the middle of the month telling us that buyers are being more aggressive.
The Moving Average Convergence Divergence (MACD) oscillator has crossed to the upside for a cover shorts buy signal and is only its way towards the zero line.
