Available COT symbols

The legacy report is broken down in three categories: Commercial traders, Non-commercials traders and Nonreportable positions (small traders). We prefer the traditional report whose interpretation guidelines are widely available and which also has the benefit of having more historical data.

Currently, provider includes Futures only COT data in "legacy" format for the following market groups:

How data is stored

Each symbol has a description of the contract/instrument. Here is the COT data file key:

  • Date = Date
  • Open = Large Speculator Long
  • High = Large Speculator Short
  • Low = Commercial Hedger Long
  • Close = Commercial Hedger Short
  • Volume = Small Trader Long
  • SmallTraderShort named series = Small Trader Short


SetBarColors(Color.Gray, Color.Gray);

Bars commitment = GetExternalSymbol("Commitment Of Traders", "AD", true );

DataSeries largeFundsLong = commitment.Open; DataSeries largeFundsShort = commitment.High; DataSeries commercialLong = commitment.Low; DataSeries commercialShort = commitment.Close; DataSeries nonReportableLong = commitment.Volume; DataSeries nonReportableShort = commitment.FindNamedSeries("SmallTraderShort");

ChartPane cPane = CreatePane(50, false, true); PlotSeries(cPane, nonReportableShort, Color.Blue, LineStyle.Dashed, 1);

Alternative provider

There's an alternative provider for COT data: Quandl. Unlike this "legacy data" provider, it includes Open Interest and supports the CoT data in "new format".
