chellester,
Its Metastock math!
Okay try this. Put Sum(Cum(1),2); into your indicators and plot it on
a chart. On bar 2 you will get a value of 3. The value for bar 3 is 5
and bar 4 is 7. In other words it increases by a value of 2 with each
new bar. Doesn't make sense does it?
We know that Cum(1) is just a 1 bar count.
If we look at the explanation for summation we get:
SYNTAX sum( DATA ARRAY, PERIODS )
FUNCTION Calculates a cumulative sum of the DATA ARRAY for the
specified number of lookback PERIODs (including today).
If I had to guess I would say that it is the "including today" that is
the culprit.
Maybe Roy will have a better answer.
