COT Stochastic Oscillator

Overview

The COT Stochastic Oscillator is a concept suggested by Murry A Ruggiero in his 1997 book Cybernetic Trading Strategies. The source data for the tool is the COT (Commitment Of Traders) Report released by the Commodity Futures Trading Commission (CFTC). That report lists the number of outstanding futures contracts (Open Interest) of a number of US Futures/Commodities and breaks that report into three categories:
  • Commercials: The main producers and consumers of commodities. eg Wheat farmers are producers and Bread makers are consumers.
  • Large Speculators (non commercial).
  • Small Speculators.
Large and Small Speculators have the same mandate, they buy and sell long and short contracts seeking to profit from changes in the value of the commodity. The difference between large and small is simply the number of open contracts they hold. Both Commercials and Large Speculators have an obligation to report their positions to the CFTC. The numbers ascribed to the Small Speculators is the residual after the other groups have reported.

In the report, each line is the net number of Long Contracts - Short Contracts. So if a group was bullish, we would see a net long (or positive) value.

Ruggiero suggested that the actual level of the components of a COT report were less important than whether the levels were near recent highs or lows. To create an indicator around this, Ruggiero suggested a Stochastic calculation with is simply a ratio of the current value within the range of values from the lowest to the highest in the lookback period. The lookback period is defined by the Base Stochastic and represents the number of weeks the stochastic calculation is performed over.

This tool provides the results of the stochastic calculations for each of the groups in the COT Report.



To add the tool to your chart, select the tool from the Data tool group, and left-click on the chart to add the tool. Optuma will then draw the tool in a window below the chart using the default settings.

Scripting Function: COTO()

Actions & Properties


Actions


Copy Data to Clipboard: Will copy the tool's values to the clipboard which can then be inserted into a spreadsheet, for example, allowing for further analysis.

Download History: Allows all historical data to be downloaded for the tool (requires an Optuma data subscription).

Add to Toolbar: Adds the selected tool to your custom toolbar.

Apply Settings to All: When multiple COT Oscillator tools have been applied to a chart, page or workbook, this action can be used to apply the settings of the one selected to other instances of the tool. This is a great time saver if an adjustment is made to the tool - such as line colour - as this allows all the other COT Oscillator tools in the chart, page or entire workbook to be updated instantly.

Copy Tool: Allows you to copy the selected tool, which can then be pasted onto a different chart window.

Move to Back: If the tool is displaying in front of other tools or indicators clicking this action will move the tool view to the background.

Move to Front: If the tool is displaying behind other tools or indicators on the chart, clicking this action will bring the tool to the forefront.

Restore Default Settings: Click this action if you have adjusted the default settings of the tool, and wish to return to the standard properties originally installed with Optuma.

Save Settings as Default: If you have adjusted any of the tool’s properties (colour, for example) you can save the adjustments as your new default setting. Each time you apply a new COT Oscillator to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
