Post From: user2user question regarding excel formula - not a technical SC issue.

Hello traders,

many times I write alert formulas in a worksheet, assume in cell O3.
For example, if price above moving average E3>AA3 then draw an arrow at the price and automatically trigger an alert:
=IF(E3>AA3,E3,FALSE)
(I know I can write it without IF, but this is just a simplified example, in reality it is more complex).

now I want to show only one (first) arrow per 20 (next) bars (sometimes i need to show only one arrow/signal per day), what I do is:
=IF(and(E3>AA3,sum(O4:O24)=0),E3,FALSE)

the problem is, I noticed that this "sum(O4:O24)" is very CPU demanding operation, especially when I do calculations for 30k or more bars and/or in SUM use more than 100 bars...

my question: are there any cheaper ways how to show only one signal per X bars?

Thanks
