Time[0].Milisecond problem

[Kovalev]

Hello, please help to solve a problem. I'm trying to calculate the time of formation of each new bar in milliseconds.

Prescribed the following

T = Time[0].Millisecond;
Plot0.Set(T);

But the value is still 0

If we change to Time[0].Second, then everything is fine although above 59 is not considered. But I need to count in milliseconds and no limit. Please help me to solve this problem.

What you have written shows an instant in time, and a component of that instance.

You have to use the correct syntax, and the correct calculation. That only way to tell how much time has elapsed in anything is to subtract the start time from the end time, so specifying a single Time is a non-starter.

Most likely what you seek is: (Time[0] - Time[1]).TotalMilliseconds as your value.

Hello Kovalev,

Thanks for your post.

Time[0] will represent the timestamp of the bar and would not necessarily represent the time of the tick. We would only see a millisecond value for bars that have millisecond granularity in the bar timestamps.

NinjaTrader 7 does not offer millisecond granularity for time and tick based bar timestamps, but NinjaTrader 8 does have this granularity for tick based bar timestamps.

Although cumbersome, you could accomplish this in NinjaTrader 7 by using timers to measure the time between each tick (or as long as needed) and accumulate the total time in milliseconds. An example on using timers can be found below.

Guys, there was another related question
for example, I have two values A and B

if (Open[0] < Close [0] && Open[1] > Close [1]) A;
if (Open[0] > Close [0] && Open[1] < Close [1]) B;

I need to calculate how many seconds have passed between these two conditions, that is, for example,
T = (B - A).TotalSeconds;

but how do I map variables A and B to DateTime?

Hello Kovalev,

You could make your own DateTime variables and assign these variables a value based on your conditions. Time[0] will still represent the timestamp of the developing bar and not the actual tick, so you may wish to monitor DateTime.Now with CalculateOnBarClose=false to get the current time for the iterating tick. Keep in mind, when you subtract two DateTime objects, you get a TimeSpan.

Here is an example that shows two DateTime variables being assigned DateTime.Now, having 30 seconds added to the first DateTime variable, and then the difference between the two DateTime objects printed in the output window.

private DateTime A, B;
protected override void OnBarUpdate()
{
	A = B = DateTime.Now;
	A = A.AddSeconds(30);
	Print((A - B).TotalSeconds);
}

I've included a link to a reference sample for manipulating DateTime objects. Since DateTime objects are a general C# concept, there are lots of external resources that could be referenced for further demonstrations.
