EL: Returning Last Signal Name...

["Brian" <blink64@xxxxxxxx>]

Is there a command in EL that will return the signal of the current open
position?  Is there one that can reference names of past signals such as
PositionEntrySignal(1) where 1 refers to the the next to last entry signal
name. (By entry signal name, I'm referring to the "S1" in this statement
Sell ("S1") On Close.)  I'm trying to detect, within the system code, what
signal was last executed without adding my own flags.

Thanks,
Brian.
