Average: barssince, cum(1), sum ??Hi Corey,The
formula works, but not to the value I'm trying to average. Maybe I didn't
explain my self correctly.If I looking back on a time period of 250
days. I want to know how many actual bars were above .15, ie. was it 30 or
60 or etc..., that were above the 250 day period.I then want to take
value of the # of bars up (lets say is was 30 bars)and divide this by the #
of bars (30).My son has been trying to help me out with this, and the
following is what he got so far, but be aware, this script does not run
because it has syntax errors. Damn those syntax's!PPO =
(EMA(C,20)-EMA(C,50)) / EMA(C,50);y = 0 ;x = 0;ppav = 0;ppa =
0;while (y != 250 ) // keep going until you have 250
bars{ if (Ref(ppo,-y) > 0) { // checks that the bar
-y(past bar) is above 0 x++;
y++; //adds 1 to the number of bars to go back}}t =
x;while (x != 0) { // keep going through all the barsppa = ppa
+ Ref(ppo,-x); //adds all the past ppo's above 0 together x = x - 1;
// counts down untill there are no bars
left}Donna--- In amibroker@xxxxxxxxxxxxxxx, "CS"

new to AB and am having trouble determining the code concepts of the AFL
language. What I'm trying to code is a simple math function, but no
matter how many different variables I use, I can't get it J. I have tried
using functions of barssince, cum(1), sum, = =, y !=, ++y, but I can't put
any of it together to obtain my value.> >

days, that PPO was above .15 then divide the sum value by the total #
of count days (bars),over my time frame -- x =250 days, that PPO was above
.15. Hence my average.> > >
