Problem with KAMA difference indicator

[nescio]

Dear support and forum members,

I was searching for an answer to my problem, but couldn't find one on the forum or internet. Hoping it will not sound to ridiculous to you, here is what I am trying to solve:

I would like to construct an indicator that plots the difference between KAMA[0] and KAMA[n], n days ago; for simplicity I assume n=3. First I coded in OnBarUpdate():

Plot0.Set(KAMA(Close,2,10,30)[0]);

to just display the KAMA[0] value in a seperate plot which worked out perfectly on a newly opened chart. I then close the chart changed the code to:

Plot0.Set(KAMA(Close,2,10,30)[0]-KAMA(Close,2,10,30)[3]);

Saved, recompiled, opened a new chart, but nothing showed up in the seperate plot anymore, just the scale from 0 to 1. When I opened the data window no values were displayed for Plot1.

Can somebody help me out with this?

Thank you in advance, kindest regards,

nescio

Thanks for your really quick answer. I helped, but now my indicator looks weired as you can see in the screenshot. Any idea?

I changed the code to:

            if (CurrentBar < 3) 
            {
                return;
            }
            if (Close[0] > Close[1]) 
            {
                Plot0.Set(KAMA(Close,2,10,30)[0]-KAMA(Close,2,10,30)[3]);
            }

Found the problem myself. Used the wrong if clause from copy and pasting from the code you provided. Thank you for your quick support!
