Hi Robert,
I think a lot of your questions can be answered by the 'Cum(1)'
function, which simply counts from 1 onwards. So if your formula
should only kick in if you have 300 data points, something like
Cum(1) >= 300
will only return true if that condition is met. You can parameterise
it easily, say
Cum(1) >= par1
To count the number of bars a given formula is available, say a moving
average, you can use something like
Cum(Mov(C,200,S)>0)
which will count the number of days this formula was above 0. So if
you work with things that can also take on negative values, you have
to adjust accordingly, but the idea is the same. This only starts
counting once the formula 'works', ie after the first 200 days are
available.
Hope this helps. If all else fails, use exponential averages, which
theoretically start working from day 1 (although I have a feeling MS
may treat it differently).
