Re: How to calculate from 1st bar of the day?

["Joe" <jgb@xxxxxxxxxxxxxxx>]

I guess I miss stated what I was hoping to do. I'm using 2000i and want to
plot a linear line based upon the open of the open of the first bar of a
day. I can do it based on the open of the day before, or the day before
that, just not on the day that is trading.

Any ideas appreciated...

So you want a function to return a constant value throughout an
intraday chart, changing only at the open of each day.  It's not
trivial.

{Function: myfunction}
Inputs: price(NumericSeries), b(NumericSimple);
Vars: x(0), y(0), result(0);
if time = FirstBarStartTime then begin
   {calculate your function based on the open}
   {make sure you do it so that your variables change ONLY within
   this section.  Do not call any other series function, only simple
   functions.  If you use canned functions like RSI or CCI or
   XAverage, then you must replicate that code here, and save your
   own values of previous prices for use next time this part of
   the code is executed}
   result = {whatever}
end;
myfunction = result;
