UNDEFINED

 

n/a

 

Using constants makes your code easier to understand.

 

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
