Your formula here gives a Math Error:
"Division by zero: 4"
Tho multiplied by 100, the 1st part of your formula sometimes
gives strong >-200 negative values (eg well below 0), the
above error is not related to these negative values(see also below).
The 2nd part, however, here gives at least 4 times
(actualy sometimes 8+ times) a value of 0.
(This is testing BAAN Comp.'s history in €uro's).
You will have to solve this error first before continuing, for as
unpredictable results, eg actual calculation bugs (f.i. "straight lines")
are bound to follow.
(Tho contra your calculations and thinking, these lines
are still program's 'proper' calculations (just turning buggy
from the above error)).

=========================================
Math Errors (MSK6.5 Help - p. 282)
If you attempt to plot (or execute) a formula that contains math errors,
the following dialog will appear prior to plotting the indicator.
***The dialog shows the number of occurrences for each error.***
Division by zero.
A formula is dividing a value by zero.
For example, the formula "(ref(close,-1)-open)/(high-low)"
will produce a division by zero error if the high and low are equal.
