Please explain Rising () on 3 minute chart

[Wizard111]

I am trying to determine when the SMA is rising. I am using the following code :

if (Rising(SMA(50)))
{

Most of the time it is correct however every once in awhile for one bar it gives an incorrect signal.
I am using a 3 minute chart. When I use Visual Studio I notice that the code is being run at three time per bar. The first time the SMA 50 value match what is on the chart. The second time the SMA 50 value is changed. Both have the time stamp of 1330. Could you please explain why this is happening?

Also here is my Initialize function where I set CalculateOnBarClose:

protected override void Initialize()
{
// Add a 15 minute Bars object to the strategy
Add(PeriodType.Minute, 15);

//Add(Stochastics(3, 5, 2));

CalculateOnBarClose = true;


//EntryHandling = EntryHadling.UniqueEntries;
}

Values the first time:
Rising(smav50) false
Mom_Value 54.2986425339362
Past_Mom_K 40.196078431372108
ToTime(Time[0]) 133000

Values the second time:
Rising(smav50) true
Mom_Value 29.411764705882362
Past_Mom_K 54.2986425339362
ToTime(Time[0]) 133000

Values the third time:
Rising(smav50) false bool
Mom_Value 65.384615384614932 double
Past_Mom_K 29.411764705882362 double
ToTime(Time[0]) 133300 int

Value the fourth time but notice the time changed:

Rising(smav50) false bool
Mom_Value 65.384615384614932 double
Past_Mom_K 65.384615384614932 double
ToTime(Time[0]) 133600 int

Could you please explain why this is happening? Is it running 3 times because this is a 3 minute chart? At least at the 1330 bar the 1st and 3rd values matches the SMA 50 on the chart with is down. The 2nd time does not match the SMA 50 on the chart.
I do not want to assume I can disregard the 2nd time value.

I have also attached the chart. Notice the green arrow.

Thanks advance you for any help

Hello Wizard111,

Welcome to the forums and thank you for your inquiry.

Without the full code I am only left to speculate at the output received.

With the information given, I see that you have a multi-series NinjaScript. If you are not using BarsInProgress checks in your code, along with minding the BarsArray used for input to your strategy's indicators, or using Times, Closes, etc. you can see some possibly unintended results.

For example, on the close of the 15 minute bar, you will have an OnBarUpdate() iteration for that data series, and if your primary data series closes at the time, you will get another iteration for that data series.

I would advise to use prints for Times[][] and CurrentBars[] while debugging, and I would advise to make sure you are using the right BarsArray for your strategy indicators as well as appropriate logic to limit your strategy to iterate on certain BarsInProgress'.

All of these items can be referenced in the Multi Series NinjaScript documentation which is an important read for building any Multi Series NinjaScript. This information as publicly available, and I will provide a link below.

I have commented out the add statement and this resolved my issue. I will do more research on the Multi Series NinjaScripts.

Thanks again
