TradeStation’s COT (Commitment of Traders) Indicator:
TradeStation COT Indicator
TradeStation now includes the historic COT (Commitment of Traders) report in the form of an indicator.
If you can plot it then you can use it in a Strategy. The following code listing takes the Indicator code and with very few modifications turns it into a trading system.
{
Net positions of various groups of traders from the CFTC's weekly Commitments of
Traders report. "Net" positions are calculated by taking the number of contracts
that a group of traders is long and subtracting the number of contracts that that
group of traders is short.
The user input "FuturesOnly_Or_FuturesAndOptions_1_or_2" determines whether the
CFTC's "Futures Only" report is used, or the "Futures and Options" report is
used to determine the positions of the various groups of traders. By default, the
"Futures Only" report is used.
Plot1: Commercial traders' net position
Plot2: Non-commercial traders' net position
Plot3: Speculators' net positions, for speculators not of reportable size
Plot4: Zero line
If an error occurs retrieving one of the values used by this study, or if the value
is not applicable or non-meaningful, a blank cell will be displayed in RadarScreen or
in the OptionStation assets pane. In a chart, no value will be plotted until a value
is obtained without generating an error when retrieved.

COT Indicator Converted To Strategy
Line numbers 90 and 91 informs TS to take a long position if the Net Commercial Interests are positive and a short position if the Commercials are negative. I kept the original comments in place in case you wanted to see how the indicator and its associated function calls work. The linchpin of this code lies in the function call FundValue. This function call pulls fundamental data from the data servers and provides it in an easy to use format. Once you have the data you can play all sorts of games with it. This is just a simple system to see if the commercial traders really do know which direction the market is heading.
if you test this strategy on the ES you will notice a downward sloping 45 degree equity curve. This leads me to believe the commercials are trying their best to use the ES futures to hedge other market positions. If you go with the non Commercials you will see a totally different picture. To do this just substitute the following two lines:
If CommNet < 0 then sellShort tomorrow at open; If CommNet > 0 then buy tomorrow at open;
With:
If NonCommNet < 0 then sellShort tomorrow at open; If NonCommNet > 0 then buy tomorrow at open;
I said a totally different picture not a great one. Check out if the speculators know better.
Hi-Res Edition Just Added to Easing Into EasyLanguage Series
Hello to All! I just published the first book in this series. It is the Foundation Edition and is designed for the new user of EasyLanguage or for those you would like to have a refresher course. There are 13 tutorials ranging from creating Strategies to PaintBars. Learn how to create your own functions or apply stops and profit objectives. Ever wanted to know how to find an inside day that is also a Narrow Range 7 (NR7?) Now you can, and the best part is you get over 4 HOURS OF VIDEO INSTRUCTION – one for each tutorial. All source code is available too, and if you have TradeStation, so are the workspaces. Plus you can always email George for any questions. george.p.pruitt@gmail.com.
This book is for those that have read the Foundation Edition or have some experience working with EasyLanguage and the various functions that help make a trading decision. This book’s audience will be those programmers that want to take an idea, that requires an observation of intraday market movements to make a trading decision, and program it accurately. If you have programmed daily bar systems, and you want to drill down and add some components that require additional market information (like what came first – the high or the low), then you have come to the right place. If you want to buy and sell short in the same day and use trade management principles such as profit targets and stop losses then The Hi-Res Edition is the book you need. There are two paradigms that EasyLanguage covers: daily and intraday bar programming. It’s the same language, but the move from daily to intraday programming can be quite difficult. Learn all the essentials and shortcuts with this edition. 5 HOURS OF VIDEO INSTRUCTION in this Hi-Res edition – one for each tutorial. All source code is available too, and if you have TradeStation, so are the workspaces. Plus you can always email George for any questions. george.p.pruitt@gmail.com.
