[amibroker] Extracting values from stand alone indicators

[gmorlosky]

I would like to use a composite indicator that can extract from any 
stand alone indicator, any specified formula values the composite 
indicator needs, that the stand alone indicator may generate.

These are the goals:
1) Have the composite indicator pull it's needed values, to combine, 
from the formula values generated by the stand alone indicators.
2) Have each stand alone indicator and the composite indicator plotted 
in separate panes.

Thanks
