How to Draw immediately on first tick of day

[dadarara]

my chart is 5min time frame
How do I draw a simple line immediately when the trading session starts on the first tick of day, when I know what is the OPEN of that day ?
I know I can run on every tick. but I dont want to overload the operation. I only need that one single tick of start of day . thats it .

Hello dadarara,

Thanks for your post.

You could create an indicator that uses Calculate.OnEachTick, create a condition in your script that checks if Bars.IsFirstBarOfSession and checks if IsFirstTickOfBar, and call your Draw method such as Draw.HorizontalLine() within that condition.

See the help guide documentation below for more information.

Note that the CurrentDayOHL indicator that comes default with NinjaTrader could also be used to get the Open of the current day.

as I asked in my original question : is there any way to do this WITHOUT running the indicator on each TICK ?

Hello dadarara,

You would need OnEachTick calculation to be able to detect when the first tick happens, when using OnBarClose you work with bar close events only.
