So the price crashed into the uptrend line on my chart and a doji formed at the end of an uptrend. When a doji forms like that during an uptrend it can signal a reversal. Keep your eye on candles like that. Also notice that if you would have sold at the doji and watched it drop it bounced right off the 50 MA. That tells you a lot. Understanding support and resistance is a huge part of being a successful trader
