有人使用CCI系统吗？ (Any one using CCI System?)

I know you may have seen the Commodity Channel Index trading system, and it looks rather simple, but looking back at the past few weeks the profits made from its buy and sell signals on the M60 and M15 are excilent. As of today, Im testing the automatic trading system on VT trader with it. Im using it on on the M15 chart with Cable, so far so good, if its profitable at the end of the week, I may take it live on the mini next week. Your thoughts, questions, concernes?
