That's right. EMA is an easy one. Other indicators are
generally possible but may require a bit more effort; for example
you might have to track the High and Low values in your synthetic
"13 minute bar" to calculate something like ADX or Stochastic.
It would be nice if there was a simple way to use existing
indicator code in this new way, e.g. the way you can use existing
indicators to refer to other data streams by saying "adx(20) of
data2" or whatever. But you can't. If you need it, you have to
rewrite it.
