This thread is a response to a request I received for some information and EFS formulas on the CCI and the Ergodic. Please feel free to share any additional information you may have about these studies and their usage.
CCI
The following description is taken from Technical Analysis from A to Z by Steven B. Achelis.
The Commodity Channel Index ("CCI") measures the variation of a security's price from its statistical mean. High values show that prices are unusually high compared to average prices whereas low values indicate that prices are unusually low. Contrary to its name, the CCI can be used effectively on any type of security, not just commodities.
The CCI was developed by Donald Lambert.
For more information and an explanation of how to calculate the CCI, click here.
Included here also is a study called, Woodie_CCI.efs, which uses a combination of several CCI studies. The chart image below shows an example of our built-in CCI study (builtinCCI.efs) as well as the Woodie CCI. The Woodie CCI is two CCI studies overlayed on each other. The main line in blue is a 14 period CCI based off of the High, Low and Close / 3. The secondary line in red, commonly referred to as a Turbo CCI, is a 6 period CCI also based off of the High, Low and Close / 3. Also, added to this study are 3 lines added at 200, 0, and -200 for reference.
Ergodic TSI
Ergodic_TSI.efs
Developed by William Blau. A little more information on the Ergodic TSI can be found in the following thread.
