return more than one answer Print()

[frankduc]

Hello,



index0 return more than one answer for ex (bar 1700, 1750, 1758) . unfortunately if i

sumOfVolumes10 of all the index0 it only returns the last answer index in index0 (1758). Is there a way i can make it return the volume of each value in index0?

Thank you

Hello frankduc,

Use an array or list.

Below are publicly available links to educational sites on c#.

I tried that but you cant use a for loop in a list?

for (int barIndex = index; barIndex <= ChartBars.ToIndex; barIndex++)
{
sumOfVolumes10 += Bars.GetVolume(barIndex);


if(cma < Bars.GetHigh(barIndex) && cma > Bars.GetLow(barIndex))
{
index0 = barIndex;

List<int> Minlist = new List<int>() {index0};

for(int y = 0; y < Minlist.Count; y++)
{
Minlist0 = Minlist[y];




Print(Minlist0);


}

}
}

Hello frankduc,

Yes, you can loop over a list with a for loop.

In the educational site DoNetPerls on list scroll to the heading For-Loop.

But its not applying the for loop to every value it just cumulate the volume from index to the last value in Minlist.


for (int barIndex = index; barIndex <= ChartBars.ToIndex; barIndex++)
{



if(cma < Bars.GetHigh(barIndex) && cma > Bars.GetLow(barIndex))
{
index0 = barIndex;

List<int> Minlist = new List<int>() {index0};

for(int y = 0; y < Minlist.Count; y++)
{
Minlist0 = Minlist[y];

for (int AIndex = index; AIndex <= Minlist0; AIndex++)

{
sumOfVolumes10 += Bars.GetVolume(AIndex);

Print(sumOfVolumes10);
}



}

}
}

Hello frankduc,

List<int> Minlist = new List<int>() {index0};

This is creating a new list and only adding 1 element which is the barIndex value.

Can you clarify your meaning when you mention: "But its not applying the for loop to every value it just cumulate the volume from index to the last value in Minlist."?

I am not seeing that any volume is being added to the Minlist list, only the barIndex value.

When you say it is not apply the loop to every value, are you using prints and seeing that there isn't the same number of prints as the Minlist.Count value?

What is the Minlist.Count?
How many prints are you seeing from the loop?

You need to reset sumofvalues10?

[frankduc]

List<int> Minlist = new List<int>() {index0}; returns more than one value. It list all the value that are equal to if(cma < Bars.GetHigh(barIndex) && cma > Bars.GetLow(barIndex))

That part index0 = barIndex; give me all the values that are equal to cma. cma is an average it return for exemple 2850. The if part return all the values in barIndex position on the chart = to 2850.

List<int> Minlist = new List<int>() {index0}; is just relisting all the values. ( bar 1020, 1025, 1030 , etc)

index is a position in bar number in the chart (lowest value in number of bars) for exemple bar 800.

I want the volume between index (800) and each value returned by if(cma < Bars.GetHigh(barIndex) && cma > Bars.GetLow(barIndex))

volume from 800 -----> 1020
800 -----> 1025
800 -----> 1030

I dont know how to do that or if its possible. What's bugging me is that i cant apply a for loop to get the volume for each values, its always returning the last value 1030.

for (int barIndex = index; barIndex <= ChartBars.ToIndex; barIndex++)
{

if(cma < Bars.GetHigh(barIndex) && cma > Bars.GetLow(barIndex))
{
index0 = barIndex;

}
}


for (int barIndex = index; barIndex <= index0; barIndex++)
{

sumOfVolumes10 += Bars.GetVolume(barIndex);
Print(sumOfVolumes10);
}

This only return the volume for 800 to 1030. but not the other 2 values.

Thank you

Hello frankduc,

A loop will simply transverse over your specified indexes. They will not return anything. You are assigning the same variable in your loop, so you are always updating it. This will always give you the last result.

If you are trying to collect a few indexes instead of updating a single variable in your loop. I recommend using a list. This is a general C# concept and documentation for using Lists can be found on Microsoft's publicly available documentation. You may also find educational C# resources external to NinjaTrader that describe using Lists.

Lists - https://docs.microsoft.com/en-us/dot...tframework-4.8

This is how you would get each object in a c# list of objects with a for loop

List<object> list = new List<object>();
for (int i = 0; i < list.Count; i++)
{
SomeMethodThatDoesSomethingWithAnObject(list[i]);
}
