American Bulls obtain there data from here http://www.endofday.com/. Now that would very likely be raw data, American Bulls providing the added value with their analysis algorithm. But the 'End of Day Data Corporation' does offer other services like free charting software, so maybe they provide some sort of algorithm as well, and can provide the outcome in a format you can work with. Having said that, it all comes down to the reliability of the provider and trustworthiness of the algorithm.
Well, that's my last 2 cents on the subject today. Need to do some work as well ;-)
