Create new dataset from logical event?

Hi all,
  I'm completely new to RapidMiner and working through the demo videos and online tutorials, but at the same time trying to piece together how I'd use RapidMiner to look for certain things in a time series. I've got a lot to learn.

  I have a goal with this code:

1) Read some SPY data
2) Take a 5 period moving average of the close (MA_Fast)
3) Take a 4 period moving average of MA_Fast (MA_Slow)
4) Each time MA_Fast crosses above or below MA_Slow build a new new data set of the SPY data on the next cycle which includes all the data columns in the original set (Date, Time, Open, High

  I'm attaching a little bit of code which _might_ do something like steps 1-3, but I'm clueless as to how I do step 4. Can someone give me a hint? The multipliers are, in my mind, are creating results outputs that would go to some other piece of logic I don't know how to do now, not the actual output of the design.

  I'm also not sure I've defined labels in the original SPY data correctly. Columns are correctly names, but really both Date and Time seem like the label to me and so far it seems RM wants to only accept a single label. I'm probably doing somethign wrong there also.

Thanks,
Mark
