Anyone familiar with programming langauges, C, Java etc. will know about for(), while() loops.
Is there a way to do this in SF?

I can do it manually by copy-pasting in the code for each iteration but it would be easier to just have this once in the program and run it each time in the loop.
The filter should return all results for each iteration of the loop.

If I had more time, which I do, I would rather look at more charts than to decipher codes, but technically you could use the count() function to achieve the loop, no? Or something along that line.

for ( int x = 0; x < 10; x++ ) // The loop goes while x < 10, and x increases by one every loop

count(x + 1,10)
x below 10

Yes, SF does allow you to emulate loop logic by using the count and sum keywords.

For example, lets say you want to detect if a stock had 15 down days (red) out of the last 20. The script would be:

set{ is_red_day, count( open is above close, 1 ) }
set{ num_red_days, sum( is_red_day, 20 ) }
show stocks were num_red_days is above 14.99
