Bought AH after a long steady climb, then a sharp dip. When it started curling up I bought for another spike and it started spiking and I went to sell and couldn't. I thought I had bought 200 shares but it was only 100. That was right at the top of the spike too. By the time I figured it out the price was falling and I had to bail. 15 min later it spiked to new highs like I expected. Very frustrated to get it right (+9%) but still take a loss (-4%).
