This is an indicator that I first became aware of in '99 thru the Pristine swing trade orientation for traders (seems like a lifetime away) that they used on a 5 day short term calculation. Combined with a positive/negative futures move, short term pullback/retracement against a rising/falling trend, hopefully to a moving average or an important level of S/R, and a number piercing +100 or -100 for a short / long this was purported to be a leading indicator and a low risk play. I still maintain the CCI on my daily chart and pay attention to it, however I consider it somewhat in the same realm as the rest of the indicators(Stoc,Macd,etc), which is simply a mathematical consideration to take into account. with the main focus on playing the market for whatever it gives you.
