This might work. I learned this from a Forex class, and the teacher showed us this technique. Its relatively simple.
Attached is the Keltner Channels indicator. Basically, when the currency crosses the top channel, you buy, and sell when it crosses the top channel on the downside. You sell when it crosses the lower channel to the downside, and buy back when it crosses the bottom channel to the upside.

If someone can program this, I would be happy to back test and forward test.

thanks,
