Hello,
I need to retrieve the first bar´s date 
(neither the first signal´s nor the first trade´s) and store it as a static 
variable for computation of a custom metric (bo.addcustommetric) in a later 
step.
I figured it´s the following, but 
supposedly, on can´t use datenum() in CBT? I only found properties for 
retrieving bar´s date within signal or trade lists!
Thanks 
Markus
