Callaway Golf Co. (ELY), a low-risk long trade

Here is a possible buy for a trade, Callaway Golf Co. (ELY). It finished off a TD Sequential and has broken its downtrend in the Combo A/D line. The longer term chart is choppy but the trend is still up.
The chart below shows something I've been experimenting with lately. It uses bands based upon the average high and average lows with one standard deviation of the price added to it. Some backtesting has shown that, after corrections, stocks that close above the upper band will keep moving up. I have been getting some nice results with just an 8% trailing stop. More work to do on this.
