JBT forces you to have both price and depth indicators.  While I was making
my multi-instrument modifications, I designed it so that you add indicators
separately for each instrument.  It then became quite apparent to me that
you could make strategies so that you manually add in feeds, and indicators
that depend on these feeds. (You could also make derivative feeds, such as a
5 deep balance and a 7 deep balance, and 15 minute bars).

Anyways, this model would let you choose the 3 depths you want.

The problem is that every addition like this will impact the optimization.
JBT is pretty lean and mean as it stands (for a java program), and it won't
take much to significantly lengthen the backtesting/optimization time.
