Aaaaach! You have to slam it with a market order when it's overbought. Don't worry about exact price. This isn't NFLX. There I can understand using only limit orders, set higher, but in this case, ESI was way overbought on low volume, so you just hit it. It was $17.32 this morning before short squeeze pushed it up as market reversed. At these market levels, I am only comfortable shorting the pops. You can still short it for a nice gain by Friday or earlier. If market pulls back tomorrow (likely), it drops like a rock.
