Hi,
To count the number of occurences of someevent
during n last bars use Sum() function:
signal = close > Ref( close, -1 );
howmanytimes50 = sum( signal, 50 );
To count total number of bars (since the first bar
loaded) use Cum() function:
howmanytimestotal = cum( signal );

Tj,In a ranking system that I am building, I have a
need to count the number of times something happens within the past "X"
number of days. For example, suppose I want to count the numberof
times in the most recent 50 days that the close was higher than the
previous days'. The only way I can accomplish this in the current
AFL is via multiple iif() statements, one for each day. Not
difficult if only a couple of days of testing is needed, but cumbersome
for a year of data!Any suggestions? Possible example:A count
function, ie, count(condition, # of days back from end of data)or
count(condition, starting # back, ending # back) with ending # back
defaulting to end of current data unless specified elsewise.Thanks,
