CCI (commodity channel index) is identifying cyclical trends in different instruments (not only commodities) and can be used to identify overbought and oversold levels. This indicator was published by Donald Lambert in an article published in October 1980 and became very popular among traders. This indicator measures an instrument's variation from the statistical mean. The CCI is calculated as the difference between the typical price of an instrument and its simple moving average, divided by the mean absolute deviation of the typical price. CCI readings below -100 are considered to be oversold, and reading that exceed +100 would be deemed overbought. >Using CCI will assist you in trading the US Dollar Index pair.
