New COT chart file format!
We have switched our file format from adobe PDF files to PNG (Portable Network Graphics). The main reason for this switch is faster chart generation. We where using Microsoft Excel to generate the charts. Now we have switched to a server side script (PHP) and a database to generate these charts. The old process took approximately 2 hours with a lot of human interaction now the whole process takes less than 40 minutes and is almost fully automated. With the new charts we can display up to 68 weeks of cot data on a 1024x768 graph, the old format only allowed 40 weeks. In the current charts we display 52-53 weeks. Also the previous option to download the Microsoft Excel data file that generate the charts will not be available, instead we are providing the data for COT in a CSV (Comma Delimited File) format and weekly price data in a CSV format as well.
