Hello nc trader, I love that you watch stocks that are in a strong trend, afterall, on these kind of stocks you make money. I wouln't buy GTAT tho, I think caution is advised. Going on to a weekly chart you can see that we are facing the previous 2 all time highs. Looking on the daily, since this move started on 06 february, there are 3 gaps. Many many years ago, a japanese rice trader, forgot his name, made a set of 5 rules for candlesticks and gaps, also known as Sakata's 5 methods. One of them was called San ku, meaning 3 gaps up. Whenever in an upmove we have 3 proper gaps up, we shouldn't buy, either wait or look for a sell. Last gap up could be an exhaustion gap. Tell me if I'm unclear and I will draw a chart for you. Keep up the good work!
