From Custom EasyLanguage development to unique TradeStation indicators and utilities
Commitments of Traders reports can be useful to all traders, giving insights into what other traders are doing in the market. But to download and format the COT data every week is very time consuming. The JAM COT Downloader automates this weekly process and makes it as simple as applying an indicator to a chart.
NEWS: On 17 July 2009 TradeStation released their own COT data that comes with the 8.x platform. My first reaction was to retire the JAM COT Downloader . However, there is a problem with the TradeStation COT data, so for traders wishing to use COT data I will continue to sell and support the JAM COT Downloader . TradeStation have dated their COT data by its compilation date, not by its release date. Therefore, any backtesting done with the TradeStation data will be invalid. For those traders interested in the accuracy of their backtests the JAM COT Downloader remains the best solution.
The benefits of using the JAM COT Downloader include:
The JAM COT Downloader is simply a TradeStation Indicator that is applied to a chart once per week. It has the following inputs.
Date Mapping Technology
The COT report data provided by the CFTC is dated as of its compilation date (known as the 'as of' date). But it is not then released until several days later (known as the 'release date'). If you backtest using the 'as of' date you are backtesting with future data, invalidating your backtest results. It is therefore important to make sure you only backtest with the release date. The 'release date' is a variable number of days after the 'as of' date and, unfortunately, the CFTC have not kept records of the actual release dates.
To resolve this issue we have incorporated Date Mapping Technology into the JAM COT Downloader . This changes the date from the 'as of' date to a 'release date'. The Date Mapping Technology incorporates knowledge of the number of business days after the 'as of' date that the report is supposed to be released (this has varied over the years) plus a knowledge of past federal holidays (taken from the JAM Economic Calendar ). Whilst the release dates cannot be guaranteed to be correct, they will be much more accurate than with any other method.
The charts below show the COT data plotted in TS 3rd-Party format. Each component (Open Interest, Large Long etc) has its own datastream (which are hidden). An indicator combines these datastreams into one display. The chart on the left is for the 'Futures Only' report for the Australian Dollar. The chart on the right is for the 'Supplemental' report for Soybean Oil.
These charts show the COT data plotted with ADE. The chart on the left is for CBOT Wheat from the 'Futures Only' report. It shows each component ( Open Interest, Large Long etc) plotted separately. The chart on the right is for NYMEX Gold from the 'Futures Only' report. The indicator is Larry Williams' COT Index.
