Highest when lookback too big

[germanmb75]

Hi, simple question, when lookback is too big in highest(), plots won't draw, how can I check if lookback is out of bound?

Example:

def lookback=10000;
plot h=if isNaN(Highest(close,lookback)) then 5 else 10;

If I set lookback to 1 plot is ok.
Thanks in advance

Have you looked at the built in function barnumber()?

barnumber only gives bars loaded, lookback in highest uses hidata far beyond that.

I played around a bit and it looks like highest() won't allow a lookback higher than 2,001. Try setting your lookback to 2001 and then 2002 and see if you get the same result.

it depends on the symbol you are using.
