Routine timing

[dieci]

Hi, I'm coding an ATS in C# (VS2019) using NTClient.dll
I'm checking the routine execution time, I use a timer, interval 20ms
I've noticed that about every 16 cycles there's one much slower, see the attacched image
What could be the cause?

Hello dieci,

You are asking about the amount of time before a method returns a value?

I can test this using a timer and calling data, I appreciate your patience.

Hi Chelsea, no, I'm referring to the amount ot time to run my routine

Here another example timer interval 10ms, almost all the point are below 10ms but some of them no...I'd like to know why and how to avoid them

Hello dieci,

If the timer is not being used to time how long it takes to receive a return value from an API method call, what are you timing exactly?

Hi Chelsea, I'll try to explain better
The timer is to run my routine every 20ms, so every 20ms I call the NTClient.dll to get the last value, make my checks and run my code
Usually this takes about 5ms to get run but some times it takes much more, as you can see from the pictures
This is a snippet...maybe it's more clear

st = new System.Diagnostics.Stopwatch();

private void TmData_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
if (NTClient == null)
return;

st.Start();
.
...here is my routine in which I call NTClient to get info or to make an entry and do my checks...
.

st.Stop();

//write a log file with a different name every hours
sw.WriteLine(DateTime.Now.ToString("HHmmss") + "\t" + st.ElapsedTicks.ToString());
}

So usually from the beginning to the end it takes about 5ms, sometimes it take much more, but as you can see from the picture it seems that those hight times have a certain logic, they repeats
with a quite regular interval
I'd like to know how to avoid that, what could I check
Hope to have been clear

Hello dieci,

It still looks like you are timing how long it takes to return a value from an API call to NinjaTrader.

Or are you timing your own custom logic?

[dieci]

Hi, I'm timing my own custom logic
I'd like to know how long it takes to run my entire code, not just an API call
I'm trying with a program that just executes a for cycle without any API call and also there there are some times it takes much more, maybe is a C# or Windows issue...

Hello dieci,

As this is an inquiry about your own custom logic in an external application and not about the NinjaTrader API this would fall outside of what our support is able to assist with.
