# COTCommercialIndex

### COTCommercialIndex <a href="#cotcommercialindex" id="cotcommercialindex"></a>

**The installation of the Technical Analysis Package is required in order to access this indicator.**

#### Description <a href="#description_21" id="description_21"></a>

The CommercialIndex is a very telling COT indicator. It puts two of the most important COT-parameters in relation to each other – the net position of the commercials to the open interest. These values are normalized and subsequently outputted. A high value of the CommercialIndex shows strong buying behavior of the commercials, whereas a low value shows strong sell pressure from the commercials. The parameters are similarly structured as with the COTReport.

The following parameters are available for the COTCommercialIndex:

* **CotType**: see [*COTReportLegacy*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#COTReportLegacy) – CotType
* **ReportType:** see [*COTReportLegacy*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#COTReportLegacy) – ReportType
* **StochasticPeriod:** see [*COTReportLegacy*](https://agenatrader.github.io/AgenaIndicator-documentation/indicators_oscillators/#COTReportLegacy) – ComparativePeriod
* **OpenInterestType:** Here you can choose between \[Native/Stochastic], which determines whether absolute values or the stochastic values of the positions of the commercials should be used for the calculation. The default setting is “Native”; do not change this if you wish to keep the informative value of the indicator.
