The beauty of studying price action is that a trader can apply their skills to ANY instrument, timeframe, and market. Just as the 50% retracement works in cryptocurrency it of course works in stocks. This happens to be a trade that I was able to catch. It took more than a day to trigger when LLY pulled back to the 50% retracement for a 4th time. A very clear level for an entry and set point of risk makes for a great trade off the level!
