Hi KB --
The statement has two parts.
The part to the right of the "=" is a statement that must be evaluated down to a single value.
To use a specific:
C != Ref(C,-1)
the "!=" is a comparison operator.
The whole thing is True if the two parts on either side of the comparison are not equal -- != is a not equal operator.
So, if today's close is 20.00 and yesterday's close was 20.50, the statement "C is not equal to Ref(C,-1)" is True, so the right hand side is True.
The "=" is the assignment statement.
Assign the variable on the left the value computed on the right hand side.
So,
Test = C != Ref(C,-1);
assigns True to Test.
It is possible that the variables are all "the same", provided that the variable on the left can take on the value that results on the right. This can happen here:
OK = OK != Ref(OK,-1);
OK is a logical variable. Say it was True yesterday and False today.
The right hand side is True, because False != True evaluates to True
So assign True to OK, replacing the previous value of False that it had before this statement.
Hope this helps,
Howard
