array of most recent bars for all instruments?

[MM345]

I have a function in one of my scripts that takes for arguments the most recent close for all bars on the chart. So, if for instance I have 3 instruments, the function call would look like:

MyFunction(Closes[0][0], Closes[1][0], Closes[2][0])

However, sometimes there will be more bars on a chart, sometimes less. Therefore I can't hard code the function arguments as above. Instead I'd like to pass a 1-dimensional array into the function, with each element representing the current close for each instrument.

MyFunction(my_array_of_current_bar_closes)

Is there an easy way to represent this array, or would I have to create it. Something like Closes[:][0]?

Hello,

Thank you for the question.

In this case, you could pass the whole Closes collection to the method and allow the method to separate the data as needed. You could also pass any type of object you want such as an array. I composed a small sample of both ways below.

protected override void OnBarUpdate()
{
        MyFunction(Closes);
	double[] myArr = new [] {Closes[0][0], Closes[1][0], Closes[2][0]};
	MyFunction(myArr);
}

void MyFunction(PriceSeries[] closes)
{
    if (closes.Length == 3)
    {
        Print(string.Format("Found 2 series: {0} - {1} - {2}", closes[0],closes[1]));
    } else if (closes.Length == 4) 
    {
		Print(string.Format("Found 3 series: {0} - {1} - {2}", closes[0],closes[1], closes[2]));
    }
}

void MyFunction(double[] closes)
{
   foreach(double close in closes)
   {
		Print(close);   
   }
}

I look forward to being of further assistance.
