Hi
Did you buy a commercial license? They should have given you a year of Premier support with the license. Then you can ask question and get help on your projects from technical support. They are very helpful. You could also post on the Wolfram Blog and see if you get anything. I don't believe its possible to get the code of the indicators inside the TradingChart function. If you hear anything back on that please let me know I would be interested in playing with that functionality as well. You could make your own function that and graph it with the ListLinePlot function.
