Have no idea how to calculate the % on options- sorry- I'm no math genius. NVDA I studied the chart the night before and did some charting on candles and AMD. I wrote down the resistance each step as it came. This morning I watched both stocks and waited to see which one was the strongest and enter. Stock was so strong after it hit my target, I let my winner run. I got out when it touched 317. I got in I believe around 309-310ish.
