All traditional indicators are available with FDC. They are provided as MACROS - any series of FDC commands can be saved as a macro and then used as though it was a single FDC command.

The above screen shows the macro that defines rsi, the relative strength index. #L refers to the moving average used in the definition, and #R refers to the target data. Thus you use it as (for example) 10 rsi IBM. Any dataset or average length can be used. As a bonus, you can see and modify the definitions at any time. Because they use basic FDC commands they can automatically be made adaptive.
