How do I get the value of a bar at a specific time

[TraderFoo]

I want to make a strategies that are based off the certain times of the trading day.

How can I get the opening value of the 6:30am bar?

Please use GetBar().

thanks. i see how that works now, but i'm trying to put it all together.

in this code sample, i'd like to get the difference between the 7:30 opening bar, and the 7:36 opening bar.

the problem is that my openPrice and the thirtySixPrice is the same.

for testing, i ran a backtest on a 1 minute frequency for the previous week.

if (ToTime(Time[0]) >= 73600 && ToTime(Time[0]) < 73700) // ToTime(7, 30, 00))
{
   int barsAgoOpen = GetBar(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 7, 30, 0));
   int barsAgoThirtySix = GetBar(new DateTime(DateTime.Now.Year, DateTime.Now.Month, DateTime.Now.Day, 7, 36, 0));
                
   double thirtySixPrice = Open[barsAgoThirtySix];
   double openPrice = Open[barsAgoOpen];
                
  Print(Time[0].DayOfWeek+" "+openPrice+" "+thirtySixPrice);

}

my output:

Monday 921.5 921.5
Tuesday 921 921
Wednesday 901.5 901.5
Thursday 914.5 914.5
Friday 920.25 920.25

Please also print what your two int variables returning as found barnumber ago, maybe your 1 min time window for the check is too limiting on a 1 min chart.

you're right. my barsAgoOpen is always 0. when i increase the time window, it just prints the exact same data for the number of minutes of that window.

are there any ninjascript examples to reference? i've imported a couple from the resource link, but none do what i'm trying to accomplish.

i.e. calculate the difference between minute bars 7:30 and 7:36 and then execute a trade based on that. (obviously the logic wouldn't be that simple, but that would get me to the next step)

Unfortunately I'm not aware any sample more specific than this one - http://www.ninjatrader-support2.com/...ead.php?t=8600
