Larry Williams COT proxy

Hi all,

I did some digging and found some code online regarding Larry Williams indicators. I am most interested in the COT proxy. But I am not sure how to convert this code to thinkscript.

Larry Commerical Proxy Index
Larry Williams said he even dont need COT report to buil COT index. Here his formula:

MovingAvg(Open-Close, bars used in average)/MovingAvg(Range,bars used in average)*50 +50

Here is my code with auto level for the limits of the COT Index since it varies on every stock. Hope you like it. ;-)

Awesome. Very much wanted and needed. Thank you!

Any chance that code could be modified for intraday periods?
Here is my code modified for use intraday. However please note that as per L. Williams the COT Proxy Index was designed for Weekly use only and tested by him. Intraday may give you allots of false signals.

Happy Trading ;-)

Thanks a bunch. Is it possible to add futures to this code ?
 
I would like to look at NQ and ES futures could these be added ?
Just for your records, Larry Williams was using the 13 weeks or 65 Daily for /SI (Silver or /Gold) and 90 days for Currencies. Actual the drop-down list is a reference to how many bars ago should count from history for the calculation.

What Larry Williams found to work best was for:
Stocks: 13 weeks or 65 days
Currencies: 26 weeks or 130 days
Metal: 26 weeks or 130 days
Meats: 13 weeks or 65 days
Softs_Sugar_coffee: 13 weeks or 65 days
Cotton: 26 weeks or 130 days
Grains: 26 weeks or 130 days
DollarIndex: 13 weeks or 65 days
Bonds: 52 weeks or 260 days
Energies: 13 weeks or 65 days

So actually instead you can select from commodity properties manual selection and add your preferable "weekly bars ago" on the settings. So as you may see is fully customizable

Hope the above assists you.
