Charles. I've done this a few times. A bounce won't take out your position. As you stock price increases so does your $ 10 & 15 floor. The higher the stock the higher your stop.
I did this when I thought the market was going to tank during election time. Turns out many sells triggered. Most recovered but not before I was able to repurchase at a lower price. This is a good option if you think your position may take a hit. Protection if you will. 1 word of caution. Your loss price may be lower if the stock dumps during after hour trading. That's all I know. Thanks Hedymoney
