Using constants improves code understanding.
The UNDEFINED can be assigned to plotting series, so that the particular series value does not plot.
Contrast this code:
IF instrument.position = 1 THEN
' Do some Long stuff here.
ENDIF
with this code:
IF instrument.position = LONG THEN
' Do some Long stuff here.
ENDIF
In the following code, is it obvious what day we are referring to:
IF DayOfWeek( instrument.date ) = 1 THEN
' Do our weekly tasks here.
ENDIF
How about in this code:
IF DayOfWeek( instrument.date ) = MONDAY THEN
' Do our weekly tasks here.
ENDIF
