/**
 * The CCI, or Commodity Channel Index, was developed by Donald Lambert,
 * a technical analyst who originally published the indicator in Commodities
 * magazine (now Futures) in 1980. Despite its name, the CCI can be used
 * in any market and is not just for commodities. The CCI was originally
 * developed to spot long-term trend changes but has been adapted by traders
 * for use on all markets or timeframes. Trading with multiple timeframes
 * provides more buy or sell signals for active traders. Traders often use the
 * CCI on the longer-term chart to establish the dominant trend and on the
 * shorter-term chart to isolate pullbacks and generate trade signals.
