RaiseNegativeDataSeries

TRUE/FALSE value.

Using constants help to make 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
